Building upon the legendary Datograph platform, the Datograph Up/Down introduces a practical power reserve indicator while incorporating numerous mechanical refinements that improve efficiency, durability and precision. The manufacture calibre retains its celebrated flyback chronograph architecture and instantaneous outsize date, yet benefits from a longer power reserve and subtle engineering improvements that enhance everyday performance. The additional “AUF/AB” display provides a clear visual indication of the remaining energy stored within the mainspring.

The visual complexity of the movement remains one of its greatest achievements. Every bridge, lever and wheel is arranged with exceptional clarity, allowing collectors to appreciate the interaction of the chronograph mechanism through the sapphire caseback. Combined with meticulous hand finishing and unmistakable Glashütte craftsmanship, the Datograph Up/Down represents one of the most admired manually wound chronographs in modern haute horlogerie.
