Today's video is slightly different than the
others: I am pulling apart and servicing my own watch. It is a 1974
Daytona Ref. 6263, which was sitting unused for a decade in a storage
box. The mechanism is a Valjoux 72 which Rolex modified in the 1960s and
renamed Rolex 727. What makes this movement special: Valjoux designed
it back in 1939! If you are a Daytona collector, then you know that back
in the 70s no one really wanted a manual chronograph. The truth is that
Daytonas were so unpopular that Rolex could not give them away! Zenith,
Omega and Breitling already had their own auto chronographs. A few
years later, in the 1980s, Rolex started fitting Zenith movements in
Daytona models. Nowadays, prices of vintage Daytonas are going through
My watch has been serviced four times in the past: March 1985, January
1990, May 1997, November 2007, and this was its fifth time.
I hope you'll enjoy it - and no, your comments won't break my heart.
