Rolex is introducing the latest generation of its Oyster Perpetual Sea-Dweller, a legend among professional divers’ watches created50 years ago in 1967. The new Sea-Dweller features a larger, 43 mm case and the new calibre 3235, at the forefront of watchmaking technology and employed for the first time in a Rolex Professional category watch.
To enhance the reading of the date, it is equipped, also for the first time, with a Cyclops lens on the crystal at 3 o’clock. The dial bears the name Sea-Dweller in red, a reference to the first model. Like all Rolex watches, the new Sea-Dweller carries the Superlative Chronometer certification redefined by Rolex in 2015 to ensure singular performance on the wrist.
The winding crown is protected by a crown guard that is an integral part of the middle case. Fitted with the Triplock triple waterproofness system, the crown screws down securely against the case, providing watertight security akin to a submarine’s hatch. The crystal, with a Cyclops lens at 3 o’clock for easy reading of the date, is made of virtually scratchproof sapphire. The waterproof Oyster case provides optimum protection for the Sea-Dweller’s high-precision movement.
An optimized blue Parachrom hairspring is fitted to the oscillator, the true heart of the watch. Patented and manufactured by Rolex in an exclusive paramagnetic alloy, it is up to 10 times more precise than a traditional hairspring in case of shocks. A Rolex overcoil ensures its regularity in any position. Calibre 3235 is equipped with a self-winding module via a Perpetual rotor. Thanks to its new barrel architecture and the escapement’s superior efficiency, the power reserve of calibre 3235 extends to approximately 70 hours.
Chronometer after casing is of the order of −2/+2 seconds per day, or more than twice that required of an official chronometer.
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.
