First launched in 2015, Rolex up to date the caliber 3255 with an optimized ball bearing for the oscillating weight in 2023.
The Rolex caliber 3255 (pictured above) is model 2, which has “Chronometer” and “Perpetual” engraved on the rotor, whereas model 1 (pictured under) doesn’t.
Rolex caliber 3255 drives hours, minutes, and heart second fingers, and the day and date wheels. The caliber 3255 makes use of Rolex’s patented Chronergy escapement (fabricated from nickel-phosphorus, this escapement is immune to robust magnetic fields), a blue Parachrom hairspring (made in a paramagnetic alloy that may deal with temperature variations and shocks). It’s geared up with a Rolex overcoil, making certain regularity in any place. The oscillator is mounted on the Rolex-designed, patented high-performance Paraflex shock absorbers, rising the motion’s shock resistance. The ability reserve is 70-hours.
