Since its introduction over a decade ago, the Datograph remains at the pinnacle of chronograph design with its combination of column-wheel control, flyback mechanism, and precisely jumping minute counter. The harmonious symmetry of the dial houses a flyback chronograph movement that allows the stopwatch to be instantaneously restarted for continuous timing, without having to stop, reset and then restart. The movement also has increased accuracy compared to other conventional chronographs as the minute hand jumps in single minute increments rather than continuously moving.
