Mechanism: The 3135 is a continuation of the 3035 series. Rolex launched it in 1977 and was profoundly different from its predecessors. As the company’s first high-beat movement, it increased the balance speed from 19,800 BPH to 28,800 BPH. This higher frequency has since become the standard across all of Rolex’s range. It also allowed the caliber to provide more accurate timekeeping and better withstand outside influences, such as shock. Like most Rolex mechanisms ending with a "5", this unit has a date function. This Rolex date-equipped mechanisms has a 'Quickset' feature as well.

The Submariner uses this exact Rolex caliber. This makes it quite large when compared with other Rolex movements. The larger size of the movement means that it is more robust and has the ability to incorporate more parts and components. This allows the watch that utilizes it to perform more reliably and durably. It also offers a frequency of 28.800 vph.
