    With A. Lange & Söhne Guarantee Certificate dated 17 April 2000 and stamped by Wempe, Bremen, operating instructions, Datograph information leaflet and original fitted black presentation box.

    Introduced at the 1999 BASELWORLD, the Datograph Flyback is the world's first chronograph based on the classic column-wheel principle with precisely jumping minute counter and patented oversized date. It stops events with a duration up to 30 minutes with an accuracy of one-fifth of a second. The precisely 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 it 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 window 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 watch.
