A. LANGE & SÖHNE. A VERY FINE 18K PINK GOLD AUTOMATIC ANNUAL CALENDAR WRISTWATCH WITH MOON PHASES, OVERSIZED DATE, ZERO–RESET FUNCTION, ORIGINAL GUARANTEE AND BOX

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.

Lange's patented "zero-reset" mechanism simplifies the synchronization of the watch with a time signal. When the crown is pulled out, it automatically causes the seconds hand to jump to the 12 o'clock or "zero" position.

Created in 1845 by Ferdinand A. Lange, the German manufacture based in Saxony encountered many challenges throughout its history. Built with the vision of producing the most technical and sough-after timepieces, the company’s activity was hindered due to bombings of the Second World War and the political instability that later followed in the region. Attached to his watchmaking legacy, Walter Lange saw the opportunity to revive his ancestor’s company after the fall of the Berlin Wall in 1989. He therefore re-established a manufacture in Glasshütte and was able to offer his first timepiece by 1994.
