Oyster Perpetual Sea-Dweller
50th anniversary, Rolex

4 May 2017

Rolex is celebrating its 50th anniversary with the Sea-Dweller, the archetype of the diver’s watch. Apparently much the same as before, it has in reality been renewed from the technical perspective: it is not so much the greater diameter (43 mm), the Cyclops magnifying lens over the date or the red name on the dial that differentiates it from its predecessors, as the latest generation of mechanics. In fact it is driven by a new self-winding movement made in-house, the 3235 caliber, mounted here for the first time in a sports model. A concentrate of cutting-edge technologies: 14 patents, a 70-hour power reserve and a series of components improved in their construction and materials, making the watch more resistant to shocks and to magnetic fields. A number of important characteristics remain unchanged, however: it is waterproof to a depth of 1,220 meters (4,000 feet), has a one-directional rotatable bezel made of Cerachrom (a ceramic material exclusive to the manufacturer), luminescent hands and markers (glowing a blue color), an extendable bracelet (by up to 7 mm, allowing it to be worn over a diving suit) and an escape valve (used to let out any helium that penetrates the case and might otherwise expand while resurfacing and make the glass pop out like a champagne cork). The main difference with respect to the past lies in the title of Superlative Chronometer: a certification defined by Rolex in 2015 that testifies to the highest levels of quality, accuracy and reliability. And it has a 5-year guarantee.
