Legible and functional
In the underwater depths, being able to read the time with absolute certainty is a matter of survival. Great
attention was paid to the legibility of the Rolex Deepsea: this professional divers’ watch features a dial
with a pared-back design and incorporates the Chromalight display. The simple forms of the hour markers –
triangles, circles and rectangles – and the hands, which are clearly differentiated in size and shape, are
filled or coated with a luminescent material emitting a long-lasting blue glow. On the bezel, the triangular
‘zero’ marker of the graduation is visible in the dark thanks to an embedded capsule containing the same
luminescent material.
High-technology ceramic
Rolex played a pioneering role in the development of special ceramics for creating monobloc bezels and bezel
inserts. Rolex has developed exclusive expertise and innovative manufacturing methods that grant it complete
independence in the production of these ceramic components.
On the new version of the Rolex Deepsea, the unidirectional rotatable bezel is fitted with a 60-minute
graduated Cerachrom insert in blue ceramic that allows divers to monitor their time underwater. The
high-performance compression ring of the Ringlock system is also made of blue ceramic – a first for this
component. The moulded, recessed graduations and numerals of the Cerachrom insert, as well as the engraved
inscriptions on the ring, are coated with yellow gold via PVD (Physical Vapour Deposition).
Oyster case and Ringlock system
A paragon of robustness and reliability, the 44 mm Oyster case of the Rolex Deepsea is guaranteed waterproof
to a depth of 3,900 metres (12,800 feet).
The Rolex Deepsea benefits from the Ringlock system, a patented case architecture developed by Rolex. This
system comprises three superposed elements: a thick, slightly domed sapphire crystal with an anti-reflective
coating, a high-performance compression ring, which withstands the water pressure, and a case back in RLX
titanium.
