A. Lange & Söhne delivers its first Datograph Perpetual Tourbillons

A.Lange & Söhne

The first customers to buy the limited edition A. Lange & Söhne Datograph Perpetual Tourbillon are now receiving their timepieces.

The watches, created in a run of just 100 pieces, combine a perpetual calendar with a flyback chronograph and a tourbillon.

ALS has been making the Datograph Perpetual since 2006 with the flyback chronograph and perpetual calendar in one watch.

For the tenth anniversary, the watch has been given an added tourbillon, visible through sapphire-crystal caseback of the watch.


Adding the tourbillon into the Datograph Perpetual was not straightforward. An initial plan to modify the existing calibre  L952.2  was abandoned in favour of a new movement created from scratch that fully integrates the three complications.

The chronograph, arranged around the tourbillon, is equipped with a column-wheel mechanism, a precise jumping minute counter and a flyback function.

The jumping perpetual calendar is paired with a moon- phase display and a Lange outsize date.
