Caliber 9002 is an evolution of the original Sky-Dweller movement caliber 9001 which came out in 2012.

Being one of Rolex’s most complicated watch movements, the caliber 9001 is already one of the most advanced calibers within the lineup. With that said, not a lot has changed from the first-generation 9001 to the second-generation 9002.

The caliber 9002 features Rolex’s patented anti-magnetic nickel-phosphorus Chronergy escapement which combines high energy efficiency and dependability. The oscillating weight has also been upgraded with a better-looking rotor with more material removed via skeletonization, though no additional performance benefits have been listed by Rolex.

Aside from these two changes, the caliber 9002 retains the 9001’s existing 4Hz frequency, automatic winding,  traversing balance bring, free-sprung balance wheel, blue Parachrom hairspring, Paraflex shock absorbers, and the oscillating weight is fitted with an optimized ball bearing. The power reserve of 72 hours remains unchanged. This movement has been COSC certified and Superlative tested to -2/+2 after being case up.
