Rolex Calibre 3235 is a new-generation self-winding movement entirely developed and manufactured in-house. With 14 patents, this exceptional in-house movement offers fundamental gains in terms of precision, power reserve, resistance to shocks and magnetic fields, convenience and reliability.

Introduced in 2016 as the replacement of Cal.3135, this movement incorporates the new Chronergy escapement patented by Rolex, which combines high energy efficiency with great dependability. Made of nickel-phosphorus, it is also insensitive to magnetic interference.

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 calibres’ regularity in any position. The oscillator is fitted on the Rolex designed and -patented high-performance Paraflex shock absorbers, increasing the movements’ shock resistance.

Equipped with a self-winding module via a Perpetual rotor, the movement provides an impressive power reserve of approximately 70 hours.
