A. Lange Sohne Recreates Datograph Perpetual in White Gold

May 20, 2009
The latest version of the A. Lange & Sohne Datograph Perpetual that boasts the smart combination of a flyback chronograph and a perpetual calendar is now recreated in white gold and with a perfectly matching grey dial. The timepiece immediately wins the heart by its supreme elegance.

The Datograph Perpetual has maintained the signature features of a Lange chronograph watch - the flyback function, the precisely jumping minute counter and the traditional column wheel mechanism.

The perpetual calendar of the timepiece displays the day of the week, the month, leap years, and the moon phase, the outsized date, as well as a day/night indicator.

The perpetual calendar mechanism needs no correction until 2100, a secular year by the Gregorian calendar. Thanks to the supreme precision of the mechanism, the moon phase deviates from the real lunar cycle by just one day every 122 years.

It is possible to individually adjust all perpetual calendar displays with help of push-pieces recessed in the case or collectively advance the displays with help of the universal corrector. The watch is provided with an interlock device that only allows the collective advancement of the displays when the crown is pulled.

The crown is used for winding the timepiece and setting the time, while two push-pieces are used for operating the chronograph function.

The highly complicated manually-wound movement of the A. Lange & Sohne Datograph Perpetual - calibre L952.1- is built from 556 parts, and most of them demonstrate meticulous hand-finishing. It incorporates plates and bridges created in untreated German silver and the balance cock engraved by hand. The movement gives an advantage of a 36-hour power-reserve.

The white gold case of the A. Lange & Sohne watch measures 41mm in diameter and incorporates a front and back in sapphire crystal provided with antireflective coating. It is presented on a crocodile strap with a Lange prong buckle also in white gold.
