Sea‑Dweller
Oyster, 43 mm, Oystersteel and yellow gold
Citizen of the deep
The Oyster Perpetual Sea‑Dweller in Oystersteel and yellow gold with a Cerachrom bezel insert in black ceramic and an Oyster bracelet.
Ceramic Bezel and Luminescent Display
Legendary divers’ watch
The 60-minute graduated, unidirectional rotatable bezel of the Sea‑Dweller enables divers to precisely and safely monitor their dive and decompression times.
It is equipped with a patented black Cerachrom bezel insert manufactured by Rolex in a virtually scratchproof ceramic whose colour is unaffected by ultraviolet rays. The graduation is coated via PVD (Physical Vapour Deposition) with a thin layer of gold. The sleek black dial features large Chromalight hour markers and hands, filled with luminescent material that emits a long-lasting blue glow for excellent legibility in dark conditions.
Black dial
Inspired by the original
The black dial of the Sea-Dweller has the large hands and indices reserved for Rolex professional models. The dial bears the name Sea-Dweller inscribed in a yellow hue, echoing the colour of the yellow gold.
When the Sea-Dweller was updated in 2017, this lettering was in red, in reference to the original model. The innovative Chromalight display on the dial pushes back the boundaries of visibility in dark environments. Its distinctive blue glow lasts up to eight hours with a uniform luminosity, practically twice as long as that of standard luminescent materials.
Yellow Rolesor
A meeting of two metals
Gold is coveted for its lustre and nobility. Steel reinforces strength and reliability. Together, they harmoniously combine the best of their properties.
A true Rolex signature, Rolesor has featured on Rolex models since the early 1930s, and was trademarked as a name in 1933. It is one of the prominent pillars of the Oyster collection.
The Oyster bracelet
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 comfortably over a diving suit.
