The Richard Lange Perpetual Calendar "Terraluna" is an horological masterpiece that combines A. Lange & Söhne's benchmark precision, inventiveness, and design competence. Featuring an orbital moon-phase display, a perpetual calendar with the Lange outsize date, a power-reserve of 14 days, and a constant-force escapement, this extraordinary time-keeping instrument represents the pinnacle of Saxon watchmaking artistry.
The Richard Lange Perpetual Calendar "Terraluna" is equally impressive on both sides. On the dial side of the 45.5mm case, the watch stands out with the regulator layout of scientific precision watches. The movement side presents an innovative and useful orbital moon-phase display that depicts the constellation of the earth, moon, and sun.
