L aunched in 1953, the Submariner was the first divers’ wrist- watch waterproof to a depth of 100 metres (330 feet). The Submariner Date, with its date function in addition to the time, was introduced in 1969. The waterproofness of both models was later increased to 300 metres (1,000 feet). Thanks to their renowned robustness, they have moved beyond the marine depths, becoming watches of choice for a wide range of sports and other activities. A true divers’ watch by design As an underwater survival tool, the Submariner’s design has been entirely dictated by the practical needs of divers. The model has evolved technically and been endowed with features to improve overall functionality. Featuring a 41 mm Oyster case, distinctive dial with large luminescent hour markers and hands, unidirectional rotatable bezel and Oyster bracelet, the Submariner and Submariner Date are among the most recognizable watches ever designed. Contributing to the strong visual identity, a graduated Cerachrom bezel insert made from high-tech ceramic is key to their functionality. Its 60-minute graduation allows a diver to monitor diving time accurately. Reliability, robustness and functionality The Submariner and Submariner Date’s Oyster case is guaranteed waterproof to a depth of 300 metres (1,000 feet). The Triplock winding crown – fitted with a triple waterproofness system – screws down securely against the case, providing increased water resistance. Designed to be both robust and comfortable, the Oyster bracelet is equipped with an Oysterlock safety clasp,

Watches in the Submariner range are symbols of reliability and among the most recognizable timepieces ever designed.

Chronometer status is symbolized by a green seal and is coupled with an international five-year guarantee. A key to the deep The Submariner was created specifically for underwater exploration and diving. When it first came out of the Rolex workshops, the watch was an immediate success with many pioneering deep-sea professionals, who were asked to test it. One of those trailblazers was Dimitri Rebikoff, a French engineer and underwater photographer. In his 1953 report, Rebikoff wrote that it had performed outstandingly well in trials: “We are able to confirm that this watch has not only given entire satisfaction in diving conditions which were extremely tough and particularly murderous for the material used, but that it has proved an indispensable accessory for all diving with inde- pendent equipment.”

which prevents accidental opening, and a Rolex Glidelock extension system, allowing fine adjustment of the bracelet length without using any tools. The Submariner and Submariner Date are equipped with calibre 3230 and calibre 3235 respectively, self-winding mechanical movements entirely devel- oped and manufactured by Rolex. Their architecture, manufacturing and innova- tive features make them singularly precise and reliable. Both movements’ power reserve extends to approximately 70 hours. Superlative chronometer certification Like all Rolex timepieces, watches in the Submariner range are covered by the Superlative Chronometer certification. This designation testifies that every watch has successfully undergone a series of tests conducted by Rolex in its own laboratories. The Superlative
