The **Datograph Perpetual** is a wristwatch from [[A. Lange & Söhne]].

[[2006]], Lange had presented the first version of the [[A. Lange & Söhne Datograph Perpetual|Datograph Perpetual]]. This supplemented the [[A. Lange & Söhne Datograph|Datograph]] original model from [[1999]], a [[flyback chronograph]], with the additional [[complication]] of a [[perpetual calendar]].

[[2010]], a rose gold-cased version was released, which already featured the characteristics of the modified dial design also present in this [[2015]] model. The influence of [[Jeromé Lambert]], who now holds a leading position at the [[Richemont]] group (CEO as of [[2018]]), is seen as essential here. He encouraged a departure from the rather conservative and stiff design and a turn towards a more modern, clearer design. Thus, the 2010/2015 datograph can be seen as a good illustrative example of this update.

Bâton indexes in rhodium-plated gold on the dial instead of the previous Roman numerals emphasize the clean design and now identify the watch as a member of the revised [[Saxonia]] family.

The case diameter is 41 mm, the power reserve is 36 hours.
