    Accompanied by A. Lange & Söhne presentation box, certificate and corrector.

    The perpetual calendar has traditionally been an enrichment of the most complicated watches, often in conjunction with chimes, repeaters or chronographs. As an isolated function, A. Lange & Söhne integrated the perpetual calendar mechanism with moon-phase display in only five pocket watches between 1887 and 1931.

    In 2001, the Saxon manufactory introduced the LANGEMATIK PERPETUAL, the first self-winding automatic wristwatch in the history of mechanical timekeeping that features a perpetual calendar, outsize date, and the patented "zero-reset" mechanism.

    The movement of the Langematik Perpetual, calibre L922.1, totals 478 parts, each meticulously finished, assembled and adjusted by hand. The Sax-0-Mat's embossed 21k gold and platinum winding rotor is placed such as to permit viewing of the escapement, with its hand-cut balance cock and Lange's whiplash precision micrometer regulation.

    The first and last syllables in the word "Sax-0-Mat" stand for the manufactory's Saxon location and its automatic winding respectively. A. Lange & Süohne's unique zero-reset function gives the "0" its raison d'être.
