A. Lange & Söhne · Richard Lange Perpetual Calendar "Terraluna"

180.032

A perpetual calendar whose real display is on the back. The caseback carries an orbital moonphase showing the moon's position relative to the earth and sun as seen from the northern hemisphere, geared accurately enough that it needs no correction for well over a thousand years. The dial side is a regulator layout with the calendar arranged around it.
