SIGNED A. LANGE & SÖHNE, DATOGRAPH FLYBACK MODEL, REF. 403.035, MOVEMENT NO. 33’982, CASE NO. 148’016, CIRCA 2000

The Datograph Flyback was introduced at the 1999 Baselworld as 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.
