Rolex Movements 21,600 vph

Hi sonimax, 

There are 21,600 bph movements from Rolex. For example, the caliber 1602: https://calibercorner.com/rolex-caliber-1602/

From that article: "Compared to its predecessors, the 1602 has a higher beat rate of 21,600vph (VS 19,800 on the 1600 and 1601)."

Thanks 🙂
