In 2020, Rolex introduced the new generation of its Oyster Perpetual Submariner and Oyster Perpetual Submariner Date, watches that exemplify the historic links between Rolex and the world of diving. Both timepieces now feature a redesigned, slightly larger 41 mm case – whose profile is highlighted by the light reflections from the case sides – and are fitted on a remodelled bracelet. This 126613LN Submariner Date features a 41mm yellow Rolesor case with a Black Cerachrom bezel and a black dial with large luminescent hour markers. This 126613LN is equipped with a three-link Oyster bracelet in yellow gold and steel and has Rolex’s Glidelock extension system. Like the other newly released Submariner Dates, it is equipped with movements at the forefront of watchmaking technology – the Submariner with calibre 3230, unveiled by the brand this year, and the Submariner Date with calibre 3235, offering both time and date functions, and used in the Submariner range for the first time. This 126613LN has a power reserve of approximately 70 hours. Waterproof to 300 meters. Like all Rolex watches, the Oyster Perpetual Submariner and Submariner Date carry the Superlative Chronometer certification, which ensures excellent performance on the wrist. The Superlative Chronometer status is symbolized by the green seal that comes with every Rolex watch and is coupled with an international five-year guarantee.
