The Rolex Submariner’s robust and functional design swiftly became iconic. With their subtly redesigned Oyster case, distinctive dial with large luminescent hour markers, graduated rotatable Cerachrom bezel and solid link Oyster bracelet, the latest generation Submariner and Submariner Date are firmly in line with the original model launched in 1953.
The Oyster Perpetual Submariner is the quintessential divers’ watch, the benchmark in its genre. This iconic timepiece has evolved with a series of patented Rolex technical innovations, guaranteeing its reliability and precision down to depths of 300 metres (1,000 feet). At home in the oceans, where it remains an indispensable instrument for every diver, the Submariner has also conquered terra firma as the watch of action with a rugged elegance of its own.
The Submariner’s unidirectional bezel is central to its functionality, and an iconic element of its design. The 60-minute markings allow divers to monitor their time underwater for safety, and the knurled edge of the bezel permits a good grip even when wet. The bezel is fitted with a Cerachrom insert in ceramic that is extremely tough, virtually scratchproof and resistant to corrosion. The numerals and graduations are engraved into the ceramic and coated with gold or platinum through a PVD (physical vapour disposition) technique that is unique to Rolex. The colour of the blue, black and green Cerachrom inserts are unaffected by ultra-violet lights.
The Submariner is easy to read in all conditions, even the murky depths of the ocean. Its bold hour markers and hefty hands are clearly defined on the dial and come alive in low light or darkness as part of the Chromalight display. This Rolex luminescent material emits a long-lasting blue glow – double that of standard luminescence – when the lights go down. The zero marker on the bezel is also visible in the dark as it is fitted with a capsule filled with the same luminescent material.
When it launched in 1953, the Rolex Submariner was the first watch to remain watertight at 100m but this achievement has been tripled since then. Its classic Oyster case has been upgraded with Rolex’s Triplock triple waterproofing system that allows it to reach depths of 300m. This winding crown is protected by a crown guard and screws down securely against the case in the same way as a watertight submarine hatch. The fluted caseback is hermetically sealed using a tool that only Rolex watchmakers have access to, thus protecting it against unauthorised tampering that could jeopardise the seal.
