The light reflections on the case sides highlight the elegant profile of the Oyster case, which is made from Oystersteel. Measuring 41mm or 36mm respectively, it is fitted with a domed bezel. One version of the Oyster Perpetual 41 has a novel configuration: its silver, sunray-finish dial is graced with hands and hour markers in 18 ct yellow gold. A second version is introduced with a bright black sunray- finish dial, and hands and hour markers in 18 ct white gold. The Oyster Perpetual 36 is unveiled with a dynamic and vibrant new look, offering lacquer dials in five new colours: candy pink, turquoise blue, yellow, coral red and green.
The new generation Oyster Perpetual model has a Chromalight display: the hands and hour markers are coated or filled with a luminescent material that emits a long-lasting blue glow in dark conditions. The Oyster Perpetual 41 and the new versions of the Oyster Perpetual 36 are equipped with calibre 3230, a movement at the forefront of watchmaking technology, launched by Rolex this year. Like all Rolex watches, the Oyster Perpetual 41 and Oyster Perpetual 36 carry the Superlative Chronometer certification, which ensures excellent performance on the wrist.
Perpetual calibre 3230
The Oyster Perpetual 41 and the new versions of the Oyster Perpetual 36 are equipped with calibre 3230, a movement entirely developed and manufactured by Rolex, launched by the brand this year. At the forefront of watchmaking technology, this self-winding mechanical movement led to the filing of several patents, and offers fundamental gains in terms of precision, power reserve, resistance to shocks and magnetic fields, convenience and reliability.
Calibre 3230 incorporates the Chronergy escapement patented by Rolex, which combines high energy efficiency with great dependability. Made of nickel-phosphorus, it is also insensitive to magnetic fields. The movement is fitted with an optimized blue Parachrom hairspring, manufactured by Rolex in an exclusive paramagnetic alloy that makes it up to 10 times more precise than a traditional hairspring in case of shocks. The blue Parachrom hairspring is equipped with a Rolex overcoil, ensuring the calibre’s regularity in any position. The oscillator is fitted on the Rolex-designed and -patented high-performance Paraflex shock absorbers, increasing the movement’s shock resistance. Calibre 3230 is equipped with a self-winding module via a Perpetual rotor. Thanks to its barrel architecture and the escapement’s superior efficiency, its power reserve extends to approximately 70 hours.
