It stops events with a duration up to 30 minutes with an accuracy of one-fifth of a second. The precise jumping minute counter allows easy reading of the stopped time. The flyback function allows the chronograph to be instantaneously reset to zero during an ongoing measurement by simply pressing the chronograph button. As soon as the button is released, a new timing cycle begins, hence eliminating the need to stop a measurement and reset the stop hand before starting a new timing. The patented oversized date in the twin gold-framed aperture ensures excellent legibility. The movement consists of 406 parts, the plates and bridges are made of untreated German silver and finished with circular graining and Glashütte ribbing. The balance bridge is manually engraved with a master’s personal free-hand technique, making each Datograph a one-of-a-kind timepiece.
