Info

This is the world's first automatic wristwatch with perpetual calendar, big date indicator and patented "Zero-reset", where the indications of the Calendar and of the moon phase both can be individually switched and also together by using the main pusher. Only on 28 February 2100, the display must be incremented manually by one day with a small pusher. The moon phase display is very precise: Once set precisely, it differs after 122.6 years of continuous runtime only for one day of the synodic orbital period from.

The Langematik-Perpetual is available in 18ct red gold or in platinum. It is equipped with a hand-sewn crocodile leather strap or with an optional wave bracelet crafted by the finest goldsmiths. An insight into the unique self-winding manufacture movement L922.1 SAX-0-MAT is obtained through the transparent sapphire back.

Introduced in 2004, the Langematik Perpetual was produced in many different case and dial combinations, but all measure 38.5 mm in diameter, 10.2 mm thick, and have a sapphire caseback to view the beautiful Cal. L922.1 movement. Ref. 310.021 (310.221 with bracelet) has a yellow gold case and champagne dial, Ref. 310.032 (310.232 with bracelet) has a pink gold case and silver dial, Ref. 310.025 (310.225 with bracelet) has a platinum case and rhodium dial, Ref. 310.047 has a pink gold case and black dial, and Ref. 310.026 has a white gold and black dial.
