The A. Lange & Söhne Richard Lange Perpetual Calendar Terraluna

When the doors open on the annual SIHH watch fair in Geneva, there’s a stampede of journalists to the A. Lange & Söhne booth to see what new timepiece miracles the Glashütte brand has introduced. The German brand never disappoints — unless you’re looking for a 47-millimeter ceramic dive watch. This year is no exception: the Richard Lange Perpetual Calendar Terraluna ($215,100+) is a spectacular timepiece, yet another tour de force from Glashutte.

The Terraluna positively bristles with Lange’s customary watchmaking prowess and finishing excellence. The list of features is long and unique: a perpetual calendar, a 14-day power reserve, an orbital moonphase display on the back of the watch that shows the relationship between the earth, moon, and sun and, oh yeah, a constant force escapement mechanism to ensure optimal timekeeping precision over that long power reserve. We’re not even going to try to explain how it all works. Instead, we’ll leave it up to Lange’s Technical Director, Anthony de Haas. Watch, listen, learn, and yearn.
