fullsize viewCalibre J890 Chronoscope
The J890 automatic chronograph movement also achieves a 50-hour power reserve with its bi-directionally winding rotor, but it not only displays hours and minutes, seconds and the date. The power reserve display, the chronoscope feature with stopwatch, and the 30 minute and 12-hour timers complete the overall impression of a movement that redefines mechanical precision and attention to detail.
