Cal. 3035 ran from 1977 to 1988 in the 16800, 168000, 16808, and 16803. It was the first quickset Submariner caliber, with 27 jewels, a 28,800 vph frequency, 48 hours of reserve, hacking, and chronometer certification. Compared with the Cal. 1570 generation, it increased frequency from 19,800 vph and added a crown position that advances the date wheel directly. Its free-sprung Nivarox Breguet overcoil is regulated by four Microstella screws and protected by KIF Elastor.

The 1977–1988 dates above apply to the listed Submariner references, not to the caliber’s full use across Rolex models.

Two construction details separate it from Cal. 3135. Its balance sits on a cantilevered cock, and its hairspring is glued to the stud. Cal. 3135 uses a bridge anchored at both ends and a laser-welded hairspring stud.
