Another one of A. Lange & Söhne’s timepieces are getting a new metal addition. This time the beneficiary is Lange 1 Tourbillon Perpetual Calendar – it’s getting a new member in pink gold. This is one of watchmaker’s all-time favorite watches that feature two complications.

Encased in a 41.9 mm pink gold case the white dial displays the main dial at 3 o’clock. A major change on this version, the months are displayed on an outer ring whereas the earlier version had its own sub-dial. The perpetual calendar display is now set to advance simultaneously (date, day of the week, month, leap year, and moon phase.) The mechanism carries such accuracy the next adjustment of the day is not until the year 2100 and moon-phase display can run for another 122.6 years without any correction. Other details on dial include outsize date aperture at 10 o’clock, retrograde day of week and leap-year display. Moon-phase and day-night sub-dial is at 7 o’clock. Power reserve indicator is located on the main dial at 6 o’clock.

All these complications are possible because of the Lange L082.1 caliber movement comprised of 624 components. Still a patent pending mechanism, the stop-seconds of the tourbillon allows timepieces with this complication to be set precisely to the second. The mechanism is activated when the crown is pulled. It has a power reserve of 50 hours. The workings of the richly decorated movement can be viewed from the sapphire crystal case back.
