Reliability, robustness and functionality
The Submariner and Submariner Date’s Oyster case is guaranteed waterproof to a depth of 300 metres (1,000 feet). The Triplock winding crown – fitted with a triple waterproofness system – screws down securely against the case, providing increased water resistance.
Designed to be both robust and comfortable, the Oyster bracelet is equipped with an Oysterlock safety clasp, which prevents accidental opening, and the Rolex Glidelock extension system, allowing fine adjustment of the bracelet length without using any tools.
The Submariner and Submariner Date are equipped with calibre 3230 and calibre 3235 respectively, self-winding mechanical movements entirely developed and manufactured by Rolex. They offer outstanding performance, particularly in terms of precision, power reserve, convenience and reliability. Both movements’ power reserve extends to approximately 70 hours.
