Cal. 3035 was an automatic movement with date produced by Rolex from 1977 through 1988. Developed alongside the Oysterquartz 5035, Cal. 3035 represented a new standard for movement design and production in the 1970s. Cal. 3035 was phased out in 1988, replaced by the updated Cal. 3135.
Cal. 3035 was used in many famous Rolex models in the 1980s, notably the Submariner.

Compared to the predecessor Cal. 1575, Cal. 3035 was much-improved. The balance speed was increased from 19,800 to 28,800 A/h and it gained a quickset date feature, though it only advances the date wheel. The hacking balance wheel features a free-sprung Breguet overcoil hairspring and Microstella regulation.
It is a 28,800 A/h 12.5 ligne movement with bi-directional automatic winding and chronometer certification. The movement is 28.5 mm in diameter and 6.3 mm thick, with 27 jewels. It has a power reserve of 48 hours.
The movement can be manually wound with the crown in position 1. Rotate the crown clockwise to wind the mainspring.
The date wheel is advanced with the crown in second position (one notch out). Turn the crown counter-clockwise to advance the date wheel by one day.
The time is set with the crown in third position (pulled all the way out). Rotate the crown counter-clockwise to advance the minute and hour hands and clockwise to turn them backward.
