The present Saxonia Annual Calendar watch stands out by its excellent condition and presence of the original accessories.

This masterpiece of A. Lange & Söhne’s production features a perpetual calendar, an oversized date and the patented zero reset mechanism allowing the calendar displays as well as the moon phase indication to be advanced either individually or collectively.
Once correctly set, the date display remains accurate until the next secular year occurs. The moon phase mechanism is also stunningly accurate: after 122.6 years of uninterrupted operation, it deviates from synodic lunation by merely one day.
