A. Lange & Söhne Langematik-Perpetual

Posted by wristwatch on September 9, 2007

With this showpiece of ingenious technology, Lange demonstrates that the usefulness of mechanical wristwatches can indeed evolve further even after 100 years. All indications of its perpetual calendar – the date, the day of the week, the month, the 4-year/leap-year display, and the moon phase – can be advanced separately with individual push-pieces or collectively with one main push-piece.

In concert with the perpetual calendar, the easily legible date display is upgraded to a perpetual outsize date. It does not have to be corrected until 28 February 2100, the next date on which our calendar year must be re-synchronised with the solar year. And on that date, all it takes is a simple press of a push-piece recessed in the case. The moon-phase display is also a model of supreme precision. Once correctly set, it will move continuously for 122.6 years before the aggregate error relative to the synodic lunar orbit amounts to one full day. The small-seconds hand seems to float above the gold moon disc. It is linked with the extremely useful, patented ZERO RESET mechanism.
