The Oyster Perpetual Submariner Date in 18 ct yellow gold with a Cerachrom bezel insert in blue ceramic and a royal blue dial with large luminescent hour markers.
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.
Manufactured by Rolex from a hard, corrosion-resistant ceramic, the Cerachrom bezel insert is virtually scratchproof. A luminescent capsule on the zero marker ensures legibility, no matter how dark the environment. The bezel’s knurled edge is carefully designed to offer excellent grip under water, even with gloves.
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.
By operating its own exclusive foundry, Rolex has the unrivalled ability to cast the highest quality 18 ct gold alloys. According to the proportion of silver, copper, platinum or palladium added, different types of 18 ct gold are obtained: yellow, pink or white.
They are made with only the purest metals and meticulously inspected in an in-house laboratory with state-of-the-art equipment, before the gold is formed and shaped with the same painstaking attention to quality. Rolex’s commitment to excellence begins at the source.
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.
