The Oyster bracelet marries engineering and aesthetics, designed to be both robust and comfortable. On the Submariner and Submariner Date, it is equipped with an Oysterlock safety clasp, which prevents accidental opening, and a Rolex Glidelock extension system, allowing fine adjustments of the bracelet – without using any tools – so that it can be worn comfortably over a diving suit.
No other part of a Rolex is subject to such regular manipulation as the clasp. For the wearer, it provides crucial assurance that their timepiece will remain safely attached.
The Oysterlock clasp reconciles the demands made on the Professional watches, with a sublime blend of robust yet sophisticated engineering, simple handling, smooth lines and, above all, security.
This inventive toothed mechanism, located under the clasp cover, enables fine adjustment of the bracelet length, without tools. The Rolex Glidelock on the Oyster bracelet has 10 notches of approximately 2 mm each, allowing the bracelet length to be adjusted easily up to some 20 mm. The watch can therefore be worn over a diving suit up to 3 mm thick.
