A. Lange & Söhne, a master of fine craftsmanship, has created numerous complicated mechanisms, but many people may be surprised to learn that the brand is also focusing on moon phase mechanisms.
This mechanism, which rotates a disc to indicate the phases of the moon, has a long history, with some saying it was developed as early as the 16th century, and therefore its functionality has matured considerably.
Today, A. Lange & Söhne remains committed to the precision of lunar phases, measured over a century. Here we introduce some of their exceptional mechanisms and masterpieces.
