Richard Lange Perpetual Calendar “Terraluna“ is a luxury wristwatch by A. Lange & Söhne.
Introduced in 2014, the name of this watch refers to the vivid display of the position of the moon in relation to the earth and the sun.
The orbital moon phase display shown on the back uses three solid white gold discs to show not only the instantaneous phase of the moon but, patent pending, the respective constellation of the moon, earth and sun. It is so precise that it only needs to be corrected by one day after 1,058 years.
In addition, the Richard Lange Perpetual Calendar “Terraluna“ has a perpetual calendar with big date, display of the day of the week, month, leap year and time of day with small seconds. The displays are jumping, which increases readability. The double barrel with constant force mechanism ensures a constant power supply with a high power duration of 14 days (336 hours).
