Does Royal Oak 15510ST.OO.1320ST.09 APS Factory Audemars Piguet Super Clone Watch V2 use ceramic ball bearings

Yes, it does. The Royal Oak 15510ST.OO.1320ST.09 APS Factory Audemars Piguet Super Clone Watch V2 really uses tiny white ceramic balls at the automatic rotor axle of its integrated Cal.4302 movement. Old metal balls got complaints because they turn dry and make noise when you shake the watch. With ceramic balls, friction drops a lot. Winding is lighter, and the running feel is better from the physical structure. If you want to fix automatic rotor noise on an Audemars Piguet replica watch, this V2 ceramic bearing upgrade is the key step.
