At the 2021 Watches and Wonders, German luxury watchmaker A. Lange & Söhne released the Lange 1 Perpetual Calendar in two new versions. The Ref. 345.056 seen here is limited to 150 pieces and comes in a white gold case and an exquisite pink gold dial.

While several previous perpetual calendar models from Lange featured other complications such as a tourbillion or a chronograph, this is the second time Lange has presented one with only a perpetual calendar after the Langematic Perpetual from 20 years ago.

The month is indicated with a ring around the periphery of the dial that advances once a month. Making up the rest of the dial is a Lange signature outsize date, a retrograde day display on the left, a moon phase and day/night indicator within the seconds sub-dial, and a leap-year counter at 6 o’clock. Once set, the perpetual calendar is programmed to indicate each month change until the year 2100.

Behind the display caseback is the self-winding Caliber L021.3 movement that features stunningly remarkable finishing. The movement’s plates and bridges are crafted in German silver decorated with Glashütte ribbing, and an exquisitely engraved unidirectional winding rotor in 21-carat gold and an additional centrifugal weight in platinum.

Despite a price tag that nudges half a million dirhams, this new masterpiece from the Glasshute manufacture is set to be sold out in no time.
