Designed to be both robust and comfortable, the Oyster bracelet is equipped with an
Oysterlock safety clasp, which prevents accidental opening, and a 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. Their architecture, manufacturing and innovative features make them singularly precise and reliable. Both movements’ power reserve extends to approximately 70 hours.
