A. Lange & Söhne Richard Lange Perpetual Calendar 180.032FE 'Terraluna' Rose Gold Silver Dial (2026)

In Rose Gold, reference 180.032FE, the 'Terraluna' pairs A. Lange & Söhne's perpetual calendar with an orbital moon phase that only the owner normally sees. Set on the movement side, it turns an Earth disc, a celestial disc and the Moon to show the lunar phase and where the Moon sits relative to Earth, with the balance wheel standing in for the Sun. Lange presented it at SIHH 2014 as its first watch with a celestial display.

The Richard Lange Perpetual Calendar's front is a Silver dial of solid silver with a regulator display, and the calendar shows day, month, leap year and Lange's outsize date, which appeared in the Richard Lange family for the first time here. The Rose Gold case measures 45.5 mm by 16.5 mm, with three recessed pushers on its left flank for the calendar and moon phase, on an alligator strap with Rose Gold deployant buckle.
