Rolex Caliber 2232

The Oyster Perpetual 31 is equipped with calibre 2232; the Oyster Perpetual 36 and the Oyster Perpetual 41 with calibre 3230. These movements, entirely developed and manufactured by Rolex, were both unveiled in 2020 and introduced to these models the same year. A distillation of technology, these self-winding mechanical movements deliver out-standing performance in terms of precision, power reserve, convenience and reliability.

Calibre 2232 is fitted with a Syloxi hairspring that is produced by Rolex and patented. This silicon hairspring has a patented geometry that ensures the calibre’s regularity in any position. The movement also contains a paramagnetic nickel-phosphorus escape wheel.

Calibre 3230 incorporates the patented Chronergy escapement, which combines high energy efficiency with great dependability. Made of nickel-phosphorus, this escapement is resistant to strong magnetic fields. The movement is fitted with a blue Parachrom hairspring, manufactured by the brand in a paramagnetic alloy. The hairspring offers great stability in the face of temperature variations as well as high resistance to shocks. It is equipped with a Rolex overcoil, ensuring the calibre’s regularity in any position. The oscillating weight is now fitted with an optimized ball bearing.

The oscillator of these two calibres is mounted on the Rolex-designed, patented high-performance Paraflex shock absorbers, increasing the movements’ shock resistance.

alibres 2232 and 3230 are equipped with a self-winding system via a Perpetual rotor. The first offers a power reserve of approximately 55 hours. For the second, the power reserve extends to approximately 70 hours, thanks to its barrel architecture and the escapement’s superior efficiency.
