Rolex 1225 Description

The Rolex Caliber 1225 is a robust manual-wind movement and the successor to the Caliber 1215. Its most significant upgrade was the increased beat rate to 21,600 vph, which provided greater accuracy. This non-chronometer movement with a date function was a long-serving workhorse, famously powering the Oysterdate Precision ref. 6694 for much of its production run, embodying reliability and enhanced performance.
