Rolex Oyster Perpetual Sea-Dweller Yellow Rolesor

07 Jul 2019

Rolex introduces an Oyster Perpetual Sea-Dweller in yellow Rolesor, bringing 18 ct yellow gold to the Sea-Dweller range for the first time.

Rolesor, the combination of gold and steel on a Rolex watch, has been a signature feature of the brand since 1933. A meeting of two metals: one, noble and precious, attractive for its lustre and stability; the other, highly resistant, known for its strength and reliability. Elegance and performance all at once, the new yellow Rolesor Sea-Dweller features the bezel, winding crown and centre links of the bracelet in 18 ct 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 for colour continuity, a contrast to the red lettering in reference to the original model when the Sea-Dweller was last updated in 2017. The 43-mm Oyster case features the unidirectional rotatable bezel with a 60-minute graduated Cerachrom insert in black ceramic, of which the moulded, recessed graduations and numerals are coated with yellow gold via PVD (Physical Vapour Deposition). The crystal is of virtually scratchproof sapphire, with a Cyclops lens at 3 o’clock for easy reading of the date.

Underwater Exploration Tool

Carrying with it a rich history, the Sea-Dweller was designed in collaboration with the pioneers of professional deep-sea diving. It played a vital role in conquering the ocean depths thanks to its hermetically sealed Oyster case, initially waterproof to a depth of 610 metres (2,000 feet), then, from 1978, to 1,220 metres (4,000 feet), thanks to a Rolex patented innovatio: the helium escape valve, which allows excess pressure in the watch case built up during a dive to escape during the decompression phase. The winding crown itself is fitted with the Triplock triple waterproofness system.

Perpetual Calibre 3235

Internally sits calibre 3235, entirely developed and manufactured by Rolex. This patented self-winding mechanical movement incorporating the Chronergy escapement offers gains in precision, power reserve, shock and magnetic resistance, convenience and reliability. Fitted with an blue Parachrom hairspring up to 10 times more precise than a traditional hairspring in case of shocks, the power reserve is now extended up to approximately 70 hours.

Oyster Bracelet And Oysterlock Safety Clasp

First introduced in the late 1930s, the Oyster bracelet is particularly robust with three-piece links. Equipped with the Oysterlock folding safety clasp, it also features the Glidelock extension system which allows fine adjustment of the bracelet by up to 20 mm so that the watch can be worn over a diving suit.

As with all Rolex watches, the Oyster Perpetual Sea-Dweller is covered by the Superlative Chronometer certification redefined by Rolex in 2015, a series of tests that is twice as stringent as that required of an official chronometer. The precision of a Rolex Superlative Chronometer is between −2 /+2 seconds per day, and its status is symbolized by the green seal, coupled with an international five-year guarantee.
