The standout novelty for A. Lange & Söhne at SIHH 2014, the Richard Lange Perpetual Calendar “Terraluna” is a complicated watch that features a constant force 14 day power reserve, a regulator style dial and the trademark Big Date. The real surprise though is on the back of the watch, with the beautiful and logical Orbital Moon Phase display, with the balance wheel representing the Sun.
