What others call fine-gloss finish we call roughing
Yesterday we undertook a practical exercise; the roughing of a piece of 316L steel. Roughing simply means removing the top layer of material rapidly in order to prepare a surface for machining. In other words, think of it as levelling your block before starting the build of a house.
The tool of choice was a 4mm end mill. The machining was done in the Kern Pyramid Nano and it was Andrew and Josh's first job in the workshop.
After the milling operation the surface finish was so smooth and even that it left them speechless. Actually it's so good that the process can be applied straight away to watch bridges and finish.
We can only imagine what kind of surface we will achieve with a diamond or ceramic tool.
Certainly the credit goes to the hydro-static guides of the Pyramid Nano.

Well done Maxx Tooling
We
are impressed! On Friday we placed an order for a pneumatic-held vice
and
it arrived on Monday. That would be an impressive delivery time even for Sydney
metro - let alone for a part which flew in from Michigan US.
MAXX
specialises in custom engineered and machined parts and tool holders.
If
you visit their website you won’t find much about the company (it’s almost an
underground operation!). However, they are very serious about quality and precision.
So
what is the benefit of a MAXX solution? We can now machine a part in our 5 axes
Kern mill and then transfer the same part holder to our Makino EDM to continue
with further operations. One part, one holder, two completely different
machines and machining processes - no loss in accuracy.
And
yes, the EDM clamp held in the MAXX vice was made in Brookvale, in our
workshop.
Good job apprentices!

Heat treatment of watchmaking micro-components
Regardless
what kind of metal machining shop you intend to setup and what is your intended
product (a car engine or a watch!) your ultimate goal is to enable yourself to
do certain tasks and processes. Starting with relatively simple ones: To draw
and measure. The ability to hold and grab firmly and accurately is the next
goal. Then to cut, drill and tap, weld and solder. From then on, you are moving
into more serious operations which require sophisticated machinery: turning,
milling, grinding. Obviously your product has to look appealing so you should
invest in deburring and polishing equipment as well. Another sometimes
overlooked aspect of metalworking: The ability to soften or harden metal. And
this is precisely where we are right now.
A
number of steel watch parts (stem,
levers, screws, arbours) undergo both pre-machining
and post-machining heat treatments. A typical furnace has to provide
not only a relatively high temperature (up to 1100 C) but the temperature
has to be constant within a very tight range over a very vast spectrum
from 100 C to 1100 C. In addition, the parts compartment must remain
oxygen-free during the entire process. A quality furnace would also incorporate
an oil quenching tank and shielding with inert gas. Yes, while the basics of
metal heat treatment are rather simple and well-known, watchmaking furnaces are
fairly complex performance-wise.
Taking
into account our low volume and part size we have opted for the smallest
furnace by Borel. (Don't be fooled with its size - it weighs almost
200kg!) Borel is a Swiss manufacturer which supplies equipment to all the top
Swiss watch brands. The company was founded in 1918 by Dr. Charles Borel. As of
last year, Borel is a division of SOLO Group, located in Porrentruy, Jura.
If
you are a watchmaker or machinist specialised in micro components which require
heat treatment then we would be happy to assist - especially if you
have issues with scaling and oxidation.

An addiction to tools is no different to any other - you just need one more
Last
year we put out a questionnaire trying to figure out why you follow
us? The majority of our subscribers are here for the obvious: A love
of watches. However, there is a growing group of subscribers who are
fascinated with machining, precision and fine tools. And for them, from
time to time, we include a photo or two to illustrate our journey into
the world of 'making'. Disclaimer: since I am not the one who operates
the machines, I don't take credit for anything you'll see
here – all the credit goes to the kids.
Yesterday’s challenge: To make a tool 'fixture'. Fixtures are
work-holding devices designed to hold, locate and support raw material
or parts during manufacturing operations. There is another special
property of the fixture: it provides a means to reference and alignment
for the cutting tool.
In other words: The quality of your part is directly related to the quality of your fixture. Or, as machinists say: if you want to make a precision part, you need a super precision fixture. Which logically brings us to a challenge: If your part is a fixture, then how do you make a fixture to hold your first fixture?
To cut a long story short, two pieces of steel were individually and separately cut, then a number of holes were drilled and taped. Locating and guiding pins were inserted. Then the moment of truth: The pieces were joined together. "Where is the gap?" asked Josh. No-one replied; it was well past 10pm and he was in the workshop by himself. "I am going to engrave Andrew and Josh on this one" was the first thing he told me after arriving home close to midnight. "In that order?" I’ve asked.

he didn't hear me. His thoughts were 17,000 kilometres away. "You know,
we need to call MAXX in Michigan. They make a super precision vice, and
we need one for Kern." "Didn't we just
order one from Lang?” I asked. "Yes, but we need one more!"
And that summed it up. Addiction to tools is no different to any other: you just need - one more.

We told him he couldn't leave until he cut the perfect cube
A couple of days ago we locked Andrew up in the workshop. We told him he couldn’t leave until he cut the perfect cube. Material: stainless steel 316L grade, the same stuff the Swiss watch cases are made of. Luckily, Andrew didn’t bother asking us to clarify what perfection meant to us. To ask a watchmaker’s apprentice to cut the perfect cube on a Makino U32J is like giving the keys of your brand new Ferrari to a teenager and asking him to find out how fast it can go.
Oh, yes, the first few attempts were rather disappointing but he just kept pushing that pedal harder. On the second day he finally got his parameters right ("I was so excited I almost hugged Josh!") .
So what is perfection? The short answer is: We really don’t know. Once again, we have reached sub-micron levels where actual dimensions of a metal cube are no longer stable; where metal expands and shrinks purely due to the change in room temperature; where the measuring machine itself influences the piece measured; and where human error in acquisition of parameters is greater than the machine’s ability to measure the part.
Once again on a 10mm-side cube, to his shock and horror, Andrew has reached sub-micron precision. In Brookvale!
So what’s next? We are now ready to go to the next level: integration of CAD and CAM software so we can finally start prototyping the most intriguing, irregular shapes. Like, for example, levers and springs pictured below. By the way, these springs come from a junk box of American pocket watches from around 1890-1920. They do look scary - like an arsenal of inquisition/torturing tools! For us, they are highly motivational - if Americans could make such delicate high precision watch parts back then using 19th century machinery, surely we should be able to at least do the same today.

Who do you respect?
***Three reasons why you should invest in an Australian watch TODAY
1. We Respect You
We
respect your expectations. There is nothing more annoying and useless
than a broken watch! When you invest in a watch designed and assembled
in Australia, you are investing in a robust, reliable and repairable
watch. Rebelde is not 'just as good as any other Swiss-made watch'.
It is a timepiece designed and
hand-assembled by a third generation Master watchmaker. There is no such
thing as a broken rebelde: every single one of the 600 watches
assembled in the past 4 years is keeping time and performing as
promised.
2. We Respect You
We
know you don't see a watch merely as a sum of finely-machined micro
components. Your watch is an expression of who you are and what you
stand for. And if there ever were a brand with a story to be told - a
watch you can wear with pride - then it is your Australian rebelde. We
don’t have customers - we only have comrades and
ambassadors.
3. We Respect You
Wearing
a mechanical watch is an act of rebellion and sophistication! In a
fast-paced world where lives are governed by heartless and soulless
gadgets, mass-produced by robots, your decision to remain stubbornly
old-fashioned and to govern your life by a slow-ticking, mechanical
watch means just one thing: RESPECT! Your investment in an Australian
watch is a smart investment in the future of Australia. Thanks to
project 'rebelde' we now have 3 watchmaker apprentices and one student
of mechanical engineering who are committed to spend the rest of
their lives designing and making watches in Australia. And if we can add
just one more supporter every week, then by this time next year we
could invite one more Australian apprentice to join our team. We grow
when you respect us back.

Just another painful blister
After 10 days of
assembly the Kern Pyramid Nano was finally alive! On Wednesday night all
systems were as per specs, fluids were running cheerfully, and the spindle and
5 axis motion left us speechless. It was the time for final laser
calibration; the moment of truth. With the coolness of a pilot of a fighter
jet, Michael 'the German dude' set his Renishaw apparatus and commenced the
four hour adjustments procedure.
Now if you are not an
engineer then the next sentence and picture below will make absolutely no sense
to you, and that is perfectly fine - so no hard feelings. The total
error over the 400mm table was well under 1 micron and not more than 0.1
micron per 100mm of table travel. "So the machine is well within what
could be described as a miracle of mechanical engineering?"
we've asked. "Actually I am not sure" said cool Michael.
"What we see is not the 'machine error' itself but the error in nano-range
is most likely just the effects of environmental temperature and vibration of
the building." And finally, it all sunk in. This is precisely
why Kern calls Nano - nano. Too tired to celebrate, we quietly went
home, each of us dreaming our own nano dreams...
Around
lunch time on Thursday, I got a phone call from Josh: "Bad news,
dad. The x-axis has just disappeared of the screen. It looks like we
have a problem with the linear decoder. We are now disassembling the
entire block, Michael has cancelled his return flight and is extending
his stay for at least another week. Yes, we need a new encoder, new
cabling and Kern is sending a spare CPU unit from Germany, just in case
we need it too." The four hour sub micron calibration vanished with the X-axis without a single part being machined.
The
other day, Elon Musk's Space-X launched Zuma, the top secret US
spy satellite. But moments after the launch, like our x-axis, the
multi-million dollar satellite disappeared - literally vanished off the
radar. Yes, engineering on any scale can be heartbreaking and
engineering is not for the fainthearted.
In
January 2012, Pat Farmer accomplished one of the greatest feats in
human history. He arrived at the South Pole after the longest and
arguably most dangerous run ever. Pat ran for 21,000 kilometres - never
complaining about being tired nor disappointed, or his painfully
bloody blisters, cramps and injuries. He just ran - and that
determination - that physical and
mental triumph - put him in the company of the world's greatest
adventurers and achievers.
And
this is precisely what our "Made in Australia" project is all
about: endurance, not giving up, being tough as nails, and being
prepared to pay the price. And we'll enjoy every bit of that journey,
even when it hurts.

Workshop training exercises well past midnight
When
asked by aspiring engineers and entrepreneurs for a 'fast track tip'
Elon Musk said: instead of 40 hours per week, do 80 hours. All things
being equal you will achieve your yearly goal by June. To get there even
sooner, do 100 hours.
It’s
funny how time flies when you learn new stuff. Last night we stayed in
the workshop well past midnight. The first training exercise: a 5 x 5 mm
block with 1 mm gap. We got within 2 microns on the first go. The
second exercise: toothed cylinder, 8 mm in diameter, watch gear profile.
Then another cut: its reverse 'image'. Material
316L.
Made in Australia? You bet.
What we have learned:
If you can imagine it, you can draw it. If you can draw it, you can make it.

From the world's smallest watch brand: Makino up and running!
Yes,
we are happy. The 50 micron wire cutter has been successfully
installed. Exclusively for our rebelde comrades: here is the picture
of a first test cut. For comparison, the top surface is a standard
milling finish , the cube itself is cut by EDM. The finish can be best
described like one on the edge of a razor blade. Scary!
The
cutting time for this tiny cube: two hours. Machining cost: Just
over $120. It goes without saying that only the space, medical and watch
industries can afford such costs. Exciting times ahead!

Another week @ rebelde workshop
This
week Michael (the German technician who came to install our Kern mill),
Josh and Andrew went through hell. After four 12-hour-shift days,
the installation hit a wall with great force: the laser adjustment tool
required for 'final alignment' is still on its way to Sydney. Obviously,
this delay will cost us time and money but we are still conservatively
optimistic that by the end of next week Kern will be up and running. The
preliminary test runs are all good: the hydraulics, cooling system and
electrical/electronic commands and the main
spindle 3-hour tests are all OK.
The
complexity of the system is mind-blowing and we have learnt that no
part of the machinery can be regarded as 'auxiliary'. Each component
and each parameter is absolutely critical. For example: the oil in the
hydraulic system which is responsible for the movement of the main table
has to be chilled to an exact temperature of 21.0 C. For that to
happen, the Kern is fitted with not one but two “refrigerators”: one
which produces a cooling liquid chilled at 11.3C and the other which
'outputs' 17C. The final temperature is then finely tuned within the
3-tonne iron cast base which itself acts as a large capacitor.
Such
a fine tuning can be only achieved when one cooler is located as close
to the machine as possible, while the other is located as far away as
you can place it. The Australian summer is not helping either, with
temperatures soaring to 40C inside the factory unit. The amount of heat
generated is close to unbearable and in addition, we are drawing so
much current. Right now, the entire system is pushed to the absolute
limit which means just one thing: Further reconfiguration, more
insulation, better pipelines and a further upgrade to the electrical
wiring.
One
thing that needs to be recognised, and given credit for, is
that these guys below are just Aussie kids setting up one of the world's
most precise machines. These are the future makers of your watch so
don't forget these faces.

Josh Reporting: One crazy hashtag
"Just finished 8 days of training in
Germany, at the precision machine tool builder, Kern Microtechnik! The
red machine behind me in the photo below is the most accurate machine
tool in the world, holding a scattered position tolerance of 0.3
microns, which is a 3000th of a human hair! In fact, the research and
development team at Kern have actually drilled HOLES through human hair
with Pyramide Nano - the very same mill to be used in Brookvale

Invisible Forces In Horology
This is a cool little video showing magnetised watch pallets. Magnetism in horology is extremely annoying. The magnetism is causing erratic performance which is hard to pinpoint. Luckily, it's easy to rectify by running the pallets through a demagnetiser. The escape wheel pallets and hairspring are are three crucial components in watch escapement and all three being made out of steel are highly susceptible to magnetism.

The first month of my life
Today marks one month that I have been privileged to be a part of the Rebelde project. I have to say it has been one of the most exciting months of my life. Seeing mechanical oscillators pulled apart as if in surgery, pulling them apart myself, drawing up the 6497 movement, learning the ebbs and flows of peak hour Spit and Harbour Bridge traffic, and seeing the expensive tools and machinery that have been acquired so far. Speaking of expensive tools, I have now been gifted my first set of tweezers on the condition that I complete my apprenticeship. These may actually be more expensive per gram than the Kern. I did not dare do the math to find out as Nick may have kept them for himself. Let's hope he isn't a subscriber. It has been a dream to learn from such experienced craftspeople. I am slowly realising that I will never again "work" a day in my life.
It might seem easy work-wise but it’s not a walk in the park. There is so much to learn in both workshops (watch assembly in the CBD and drawing up and building in Brookvale) and now from March I will be learning from another Master watchmaker at Tafe.
Here’s a tip. If you are ever after professional watchmaking tweezers the Dumont Number 3 Carbon is the way to go.

Not as popular as a cat video on Youtube but who cares?
I am sure many of you remember that 6 months ago we had a major capital raising for the purpose of the acquisition of a Strausak gear hobbing machine. Strausak is the Mercedes of watch gear hobbing and I made a special trip to Geneva to meet the company director. After day one of negotiations it was clear that we were not heading in the right direction and, by the third day, the price of the machine, the cost of tooling, all added accessories, shipping and training ballooned to over $250k. This was a major disappointment and significantly more than we were prepared to invest in a gear hobber.
Geneva is really a village and a "cashed-up Aussie" sticks out like a sore thumb. It wasn't long before I was introduced to another gear hobber machine. This one was made by Affolter. There was only one small problem: I was well aware of both Affolter and this particular machine which I saw the year before. To put it simply, Affolter is a Porsche, not Mercedes C class. But due to some circumstances, the machine was a demonstrator, available for immediate delivery, with only a few hours of run time. A 911 with 100kms on the clock!
To cut a long story short, our Carrera twin turbo Affolter AF90 arrived last week and was powered up for the first time yesterday. A gear hobbing machine makes watch wheels and it is a crucial piece of equipment which will allow us to make gears in-house, in our Sydney our workshop. Clearly we are excited: the 8 axis CNC hobber is truly a piece of art in itself. But, equally important, the Affolter people are excited as well. For them, selling a machine to us meant 'ticking off' the second last continent and cementing their position as a true world-wide leader in precision gear cutting. After Australia, the only continent with no watch gear cutting machine of this precision is Africa! (This really speaks volumes about us as 'tech giants'!) We are looking forward to training in Switzerland at their factory mid next year!
The time frame: The next step for us is to design a few prototype wheels. Based on our drawings, a Swiss tool manufacturer will make custom hobbers (gear cutters). Also a third party precision manufacturer in Switzerland will make tools and holders/collets to hold each gear while cutting. This preparation work should not take more than 6 months. In June next year Josh will travel to Malleray, a tiny village in Swiss Jura (population 1,900!) to the Affolter Headquarters. With a bit of luck, we should learn how it's done, and be all set to manufacture our first prototype gears by Christmas next year.
For those of you who may wonder: What is the manufacturing cost of a watch wheel made in Australia? Unfortunately, the math is not straight forward. But if we take the cost of the machine itself out of the equation, then the tooling cost per wheel and number of wheels made 'in one go' is really what determines the cost. Our problem is that we will never make more than 200-300 identical wheels, which is just unimaginable in the gear industry! A CNC hobber like the AF90 is designed to output tens of thousands of precision, top quality wheels at a time. But we are not in mass production. Nevertheless, at 200 pieces per batch, our cost per wheel should be around $60 a piece, which is about the same you would pay wholesale for a top Swiss-brand wheel.
Here is a 14 second video of our AF90:
And here is an Affolter video of the machine in action, hobbing a watch winding pinion, diameter 3,66mm and half millimetre thick, with module of 0.19. Production time: 55 seconds:
Note the video view count: 243 views - and we've watched it probably 50 times ourselves! Yes, we are dealing here in something incredibly unimportant, not just to the general public but even to engineers (a good cat video on YouTube can generate millions of views; a half-naked squeaking singer a billon!) But sophistication is not about numbers...
Once again, from our small team: we appreciate your continuous support.

We love our collets
A
collet is a special type of chuck designed to hold either material
machined or a tool machining it. And to do so in a very special way: by
providing a firm and rigid, yet very precise grip. Collets are mighty
things and there is only one rule about them; you can never have enough
of them! Indeed, each and every machine in our workshop has its set of
collets; and some - like in the case of our Citizen lathe - come for
both material and tool holding, in a variety of styles, shapes and
sizes. All custom made too.
The
latest addition to our workshop is our lovely 30 pcs tool-holding set
from Schaublin made for Kern. These lovely collets are designed for
fast, automatic clamping on a spindle. And since the spindle speed goes
up to 50,000 RPM, you can imagine how extremely well-balanced they have
to be to retain positional error under one micron at that speed!
At
last count, we had over 150 different collets in stock. By the time we
make our first in-house watch mechanism, we are going to have close to
1,000. The good news is that a precision collet can last forever,
assuming proper care is taken. Josh is our
collet guy and he is allowed to buy them without even asking me for
approval. Actually if he doesn't buy any more before Christmas I would
be seriously upset.
Machining
is cool! Did i mention that we are looking for a watchmaker’s
apprentice? No? Well, we have to talk about that soon.

You know you've made it when...
... your product becomes a synonym for an entire industry. Which is precisely in the case of Renishaw - or renishaw.
The
Renishaw company was founded by two Englishmen: Sir David McMurtry
and John Deer in 1973. McMurtry had needed to measure fuel pipes on a
prototypejet engine. At the time, measuring machine sensors featured a
rigid 'tip' which required manual positioning and which
yielded poor repeatability when measuring delicate components. To meet
this need, McMurtry invented a spring-loaded touch-trigger probe device
tip, which he then patented. The new instrument tip was an elegant
solution and was quickly adopted by leading manufacturers who needed
measurements of ultra precision.
Our
Kern mill arrived equipped with a renishaw probe. What a
beautiful instrument! A glass enclosure reviling an electronics 'brain';
micro ruby ball on the tip of the styli; rigid - yet at the same time, a
fragile, delicate instrument. The renishaw is mounted on the tool
holder and can be 'grabbed and attached' on the main milling spindle
automatically. Of course, for those of you who are into fine machining
or coordinate
measurement systems, this precision instrument is something you commonly
see in action, on perhaps a daily basis. But for us, who have just
started our journey into watchmaking, this renishaw is a very exciting
newcomer to our workshop.
Made in the UK. Cool!
And
here is one more bit. Unlike the watch industry where every brand is
working hard to 'stamp' its name on every single component claiming that
the dial, hands, cases and all movement components are made 'in house'
(when they are clearly not) it is really refreshing to see that true
engineering companies which specialise in
high-end manufacturing are actually proud to disclose their association
with other industry leaders. And when you think of it - why would Kern
even want to make their own renishaw when Renishaw has already invented a
damn good one? Why would a world leader in the milling industry want to
make collets for its machine when Schaublin, the leader in collets, has
already reached the levels of precision required? And the list goes on -
Erowa, Siemens, Zeiss, Boch... all supplying parts and technology to
each other, for a common benefit.
While
100% 'made in-house' may be great marketing news, such a
watch mechanism is doomed to be a very average performer. Like it or
not, sooner or later, 'in house' will become a synonym for a product
which will lack the future; a product developed to please the brand
itself rather than a consumer, at the cost of innovation and technical
advancement. Open for cooperation, open for learning and sharing, an
open mind.
Quite frankly, I am so glad we are not in the watch industry anymore.

It's all about information
The year is 1850. Suppose you are a reputable country watchmaker. In your shop window you have a large dial clock and all day long your customers and passers-by would stop in front of your shop to set their pocket watches against your master clock. The question is: How would YOU know what is the correct time? Obviously this information would have to come from somewhere! The solution was simple. Every week or two you would take your best pocket watch, buy a newspaper, hop on the train, travel to London - and there you would set your pocket watch against the clock on display at the most reputable London clockmaker, who himself would have got 'his time' from Greenwich. And there, at the observatory, clocks were set and regulated by astronomers, mathematicians and scientists who were really the 'true time keepers' because they knew how to calibrate their clocks against the movement of the stars. Indeed, for a country watchmaker weekly trips to London were often the highlights of the week.
Of course, with the invention of radio, everyone with a wireless could have direct access to accurate time. Bip, bip, bip - the time is 8 o’clock.
Nowadays, we no longer need radio signals nor any effort on our behalf in order to 'know' the time. Thanks to GPS and the internet, our mobile phones and commuters are 'synchronised' countless times per day - and the time itself comes directly from the network of atomic clocks located all over the planet. In just 100 or so years we have come a long way!
However, when it comes to the 'dissemination' of some other types of information we are still facing some serious issues with accuracy.
For example, suppose that you live in Germany and you've engineered and built two superbly precise machines. One stays in Germany, while the other is disassembled and shipped to Australia. The question is once that Australian machine is reassembled how are you going to calibrate it so it will machine metal as accurately as it did before, as the one on the different side of planet?
As clever as it is, the machine itself cannot calibrate itself. As accurate as your watch may be, it will not tell you the time, unless you FIRST tell your watch what the time is! In both cases, the information has to come from an external, super accurate source.
I will not bore you with the details - but in the case of our five axes nano precision Kern mill, this outside information comes in the form of a small metal object which 'contains' crucial information. This object is machined in Germany to extremely tight tolerances, measured in a number of points, then shipped to us to be used as calibration 'etalon'. Without it, our machine could not be set.
While the geometry of 'etalon' is simple, thanks to the extreme precision with which it was machined and measured, it contains a number of crucial information. It will help us to establish the centre point of the table, work holding position, the eccentricity of the spindle, the relationship between the three main axes - and much more.
Due to the fact that it had to be mounted on the tool holder, it was manufactured not by Kern, but by Erowa, a German 'tool holding' specialist. However, after Erowa measured its dimensions, Kern re-measured it and re-certified it again, with even more accuracy. Each dimension was measured a number of times to 1/10 of 1 micron. Yes, we are talking nano!
The photos below are attached for your enjoyment. If you wonder what the cost is of this tiny piece of metal, then let me just answer this question in an indirect way: the etalon is kept in a safe and I am the only person allowed to handle it.
As you would imagine, we are now very anxious to get our mill assembled, calibrated and running. However, we still don't know when the German engineers will be able to travel to Sydney to assemble it. Christmas/New year and endless European holidays are not working for us. Patience, patience!

The art of self-promotion
It is not just bad taste, poor manners, lack of empathy - or simply just being a jerk. Self-promotion is a crime.
And
especially so in Japanese culture! I am not kidding: a poor Japanese
craftsman would rather commit a harakiri than post a message on Facebook
about the knife he hand-polished for 3 months to perfection. He would
rather take 40 lashes with the cane for failing, than one compliment for
achieving perfection. Strange.
It
is
funny, but while the Anglo-Saxon culture has almost nothing in common
with the oriental one, self-promotion is a sin even in our little
colony.
Crocodile-wrestling-tough-as-nail
sun burnt Aussies crawl under the rock at the very thought of even
being in the same room as a self-promoter. Nearly a hundred years of
exposure to Greek-ism, Balkan-ism and Latino-sim (the cradle cultures of
macho-self-promotion) made our good Aussies even more resistant and
more sceptical to any form of advertising with even the slightest hint
of 'yeah, sure, we can do this'.
"Wait
until they discover
your talent" say Mosman mums to their daughters as they jump out of
mega-monster 4WD’s, being dropped in front of $40K per year schools.
"Wait until they discover your talent" say dads dropping off boys at
multi-billion dollar ovals. And make no mistake, like mums and dads,
these very kids are already driving their own E-class Mercedes and
wearing gold watches – and they play great cricket. But to tell anyone
how good they are would be totally inappropriate. "Wait until they
discover your talent" is what every 12 year old surfer hears every time
he eats his vegemite. Be modest, be humble, be invisible; let others see
what you are really worth and give you the credit you deserve.
But
life is no
longer as it once was. "Others" are no longer a passive audience quietly
waiting for the next Sir Bradman. "Others" are us: posting selfies on
FB, Instagramming, chatting, and simply being alive; connecting, talking
and sharing.
You
see, I don't mind modesty. Actually, I much prefer to wait 'to be
discovered' than to self-promote myself. But on the other hand, I am not
a big fan of posthumous awards either.
Right
now, as I type this, we have a great need for a 10 tonne forklift to
move some equipment; we need an energetic and reliable office assistant;
a smart
and hard-working apprentice keen to learn about watches; a photographer
who won't charge an arm and a leg; a reliable local server to host our
new website; a 2KV petrol generator (not too loud!), an oven for steel
hardening, a polishing machine - which comes with expert advice and the
right polishing compounds. And we are not any different to other small
Australian businesses. Yet somehow, those who are experts in their
fields are often hard to find - because they have always been told the
same old thing; "wait until they discover you".
This
week a rebelde-owner brought in his 3 year old watch for a minor
adjustment. However, he wore that watch daily so it was heavily
scratched. So we decided to surprise him:
We pulled the watch completely apart, serviced it, polished the case,
fitted a new winding crown and seals - and even fitted a brand new
leather strap. Total charge: zero. Why? Because we simply want to show
him what we can do, and how proud we are of our workmanship. And how
much we appreciate the fact that out of hundreds of brands he put his
trust in rebelde.
And here we go - I just committed the worst crime ever: I self-promoted.
Guillotiner, make it quick.
