Oscillating pinion

Pignon oscillant | スウィングピニオン | 摆动小齿轮

The oscillating pinion, which comprises a mobile stem and two pinions, allows the Chronograph to function very efficiently by replacing the two large wheels of the anterior movements. A coupling system enables the chronograph to locate onto the watch movement with ultimate precision. The chronograph’s lightning fast start — an incredible 2/1,000th-of-a-second — guarantees the utmost in timekeeping accuracy.
