The Oyster Perpetual Submariner Date in Oystersteel with a Cerachrom bezel insert in green ceramic and a black dial with large luminescent hour markers.

It features a unidirectional rotatable bezel and solid-link Oyster bracelet. The latest generation Submariner and Submariner Date remain faithful to the original model launched in 1953. In watchmaking, the Submariner represented a historic turning point; it set the standard for divers’ watches.

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.

ALCHEMY OF FORM AND FUNCTION

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 and comfortably over a diving suit.

SUPERLATIVE PERFORMANCE

The caliber 3235 is a new-generation movement entirely developed and manufactured by Rolex. This self-winding mechanical movement is at the forefront of the art of watchmaking. A consummate demonstration of Rolex technology, with 14 patents, it offers fundamental gains in terms of precision, power reserve, resistance to shocks and magnetic fields, convenience, and reliability. It incorporates the new Chronergy escapement patented by Rolex, which combines high energy efficiency with great dependability. Made of nickel-phosphorus, it is also insensitive to magnetic interference.
