Unidirectional Rotatable Bezel An underwater tool
The Submariner's rotatable bezel is a key functionality of the watch. Its 60-minute graduations allow a diver to accurately and safely monitor diving time and decompression stops.

Black dial
For legibility underwater
The dial’s luminescent Chromalight display is an innovation that improved visibility in dark environments, an essential feature for divers. Hour markers in simple shapes – triangles, circles, rectangles – and broad hour and minute hands enable instant and reliable reading to prevent any risk of confusion underwater.

The Oyster bracelet
Alchemy of form andfunction
The Oyster bracelet is a perfect alchemy of form and function, aesthetics and technology, designed to be both robust and comfortable. It is equipped with an Oysterlock clasp, which prevents accidental opening, and an ingenious Glidelock, allowing fine adjustments of the bracelet without using any tools - and allowing it to be worn comfortably over a diving suit.
