9002

About the Rolex 9002

The 9001 was the most complex movement Rolex had built: an annual calendar, the Saros system, that distinguishes 30-day and 31-day months and needs correcting only in February, a second time zone on a rotating 24-hour disc, and the Ring Command bezel, which selects which function the crown sets. The 9002 keeps all of it and brings the base to the current specification: the Chronergy escapement, whose design the 3135-to-3235 piece explains, the Paraflex shock absorbers and a rotor on an optimised ball bearing. The reserve is 72 hours at 28,800 vph with 40 jewels, at 33 mm across, and every one is a Superlative Chronometer.

Every reference here is a Sky-Dweller of the 336xxx generation, in steel with yellow or white gold, solid gold and Everose, on Oyster, Jubilee and Oysterflex bracelets, 39 in all.

The glossary defines the annual calendar the Saros system computes.
