Mechanism: The Rolex 1220, which represents a dramatic evolution of caliber Rolex 1210. Caliber Rolex 1220 shares the same mechanical platform of caliber Rolex 1210 with the exclusion of the Breguet spring. The balance wheel oscillating frequency increases from the original 2,5Hz (18000 vph) to 3Hz (21600 vph). Caliber Rolex 1225 is a Rolex 1220 caliber with the addition of a date module. The caliber's thickness moves therefore from the original 4,27mm of caliber Rolex 1220 to the 5,07mm of caliber Rolex 1225.

Description: Manual winding movement; Escapement: Stone lever; Yoke winding system; Breguet hairspring; Shock protection Kif-Ultraflex; Escape wheel in Kif Duofix combi chuck; Regulation weights on the Balance wheel spokes.
Family Notes: The Precision is one of the most overlooked Rolex models ever made. This series is unusual not only because they are dress watches, but also because most of Precision models are powered by a manual-winding movement.
