For the past ten years, the DATOGRAPH has constituted the benchmark in chronograph design with its combination of column-wheel control, flyback mechanism, and precisely jumping minute counter together with the lucid and harmonious configuration of the dial. With a power reserve extended to 60 hours, a power-reserve indicator, and a proprietary oscillation system, the new DATOGRAPH UP/DOWN shines in a platinum case enlarged to a diameter of 41 millimetres.

The patented outsize date in the twin gold-framed aperture assures excellent legibility. The aperture of the date display was adjusted to match the bigger size of the case. It was enlarged by four per cent to preserve the balanced proportions of the dial architecture.

The DATOGRAPH UP/DOWN stops events as long as 30 minutes with an accuracy of one-fifth of a second. Thanks to the precisely jumping minute counter, the stopped time is very easy to read. The  flyback function allows the chronograph to be instantaneously reset to zero during an ongoing measurement, simply by pressing a push-piece in the case. As soon as it is released, a new timing cycle begins. This eliminates the need to stop a measurement and reset the stop hand before starting a new measurement.
