Am looking to buy a new AP Royal Oak - Already own the RO Offshore Safari model. Have read a lot about the 3120 fully in house designed and manufactured movement which they use in the Selfwinding 41mm version. What I wanted to ask is Movement 2385 that is used in the Chronograph - is this based on the 3120 or the 7750 Valljoux Movement?
Also the Movement 2326 in the Safari is this also based on the Valljoux 7750?
Any help Appreciated.
With thanks
