Ceramic Bezel and Luminescent Display

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

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

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.

Model availability

All Rolex watches are assembled by hand with the utmost care to ensure exceptional quality. Such high standards naturally restrict Rolex production capacity and, at times, the demand for Rolex watches outpaces this capacity. Therefore, the availability of certain models may be limited. New Rolex watches are exclu-sively sold by Official Rolex Jewelers, who receive regular deliveries and independently manage the allocation and sales of watches to customers. La Campanina Capri is proud to be part of the worldwide network of Official Rolex Jewelers and can provide information on the availability of Rolex watches.

Rolex created the Oyster Perpetual Sea-Dweller in 1967 to meet the challenge of prolonged underwater missions. Subsequently improved in close partnership with Comex (Compagnie Maritime d'Expertises) professionals, it is now water-proof to 1,220 metres (4,000 feet). The Sea-Dweller is specifically designed for saturation diving. Thanks to its helium escape valve, it can withstand decompression on ascent and master the return to the surface – the final phase of deep-sea exploration.
