Perlage - a traditional watch part decorating technique - consists of small, overlapping circles, achieved with a rotating, grinding tip.
Yesterday, Josh designed and made a jig, and then had a first attempt at perlage on our own main plate. I say not a bad job - actually, much better than one found on mass-produced Swiss plates. There is something special going on here: a CNC machined part receiving the final touches by hand, in the old, traditional manner. Stay tuned for more!
