    With A. Lange & Söhne International Guarantee card dated 30 June 2004, Guarantee & Services booklet, Langematik Perpetual operating instructions, manual for the watch winder, polishing cloth and setting pin. Furthermore delivered with original fitted Langematik presentation box with electrical winding facility and outer packaging.
    The Langematik Perpetual is the world's first automatic wristwatch featuring 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 by depressing the calendar change button in the band.

    Once correctly set, the date display remains accurate until the next secular year occurs: On 28 February 2100, it will need to be advanced by only one day. 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.
