Baselworld 2019: Rolex Oyster Perpetual Sea-Dweller hits the spotlight


Rolex is introducing the Sea-Dweller in steel and yellow gold, for the first time in this range. Despite some obvious fancy and dressy boost, the legendary diver still feels very masculine.

The 43-mm Oyster case features a unidirectional rotating bezel with a 60-minute graduated Cerachrom insert in black ceramic. On the new yellow Rolesor version of the Sea-Dweller, the bezel, the winding crown and the centre links of the bracelet are in yellow gold, while the case and outer links of the bracelet are in Oystersteel. On its black dial, the name “Sea-Dweller” is inscribed in a yellow hue, echoing the colour of the yellow gold. The moulded, recessed graduations and numerals are coated with yellow gold via PVD. The crystal is made of virtually scratch-proof sapphire and is fitted with a trademark Cyclops lens at 3 o’clock for easy date reading.

The Oyster case of the Sea-Dweller is guaranteed waterproof to a depth of 1,220 metres (4,000 feet). The case back, edged with fine fluting, is hermetically screwed down with a special tool that allows only Rolex watchmakers to access the movement. The winding crown, fitted with the Triplock triple waterproofness system, screws down securely against the case and is protected by an integral crown guard. The helium escape valve, patented by Rolex in 1967, acts as a safety valve. It allows excess pressure built up in the watch case during a dive to escape during a diver’s decompression phase in a hyperbaric chamber.

The new version of the Sea-Dweller is equipped with calibre 3235, a new-generation self-winding mechanical movement entirely developed and manufactured by Rolex. It incorporates the Chronergy escapement and is fitted with an optimized blue Parachrom hairspring. Calibre 3235 is equipped with a self-winding module via a Perpetual rotor. Thanks to its barrel architecture and the escapement’s superior efficiency, the power reserve extends to approximately 70 hours. The Sea-Dweller is fitted with an Oyster bracelet and equipped with Oysterlock folding safety clasp. It also features the Rolex Glidelock extension system. The price for version is CHF 15300.
