Rolex 1525 Description

The Rolex Caliber 1525 is a durable automatic movement from the 1500 family, serving as a non-chronometer alternative to the Caliber 1575. Used in Oysterdate models, it features a date complication and a 19,800 vph beat rate. With a lower jewel count of 17 and lacking COSC certification, it provided a more economical option without sacrificing Rolex’s core quality and reliability.
