The Datograph Perpetual is a wristwatch from A. Lange & Söhne.
2006, Lange had presented the first version of the Datograph Perpetual. This supplemented the Datograph original model from 1999, a flyback chronograph, with the additional complication of a perpetual calendar.
In the platinum version from 2026, the hour markers are represented by eleven diamonds in a baguette cut. The five-row platinum bracelet with a folding clasp forms a harmonious whole with the case.
The watch is limited to 50 pieces.
