Lot Essay

The Sax-O-Mat Langematik Perpetual is the world's first automatic wristwatch featuring a perpetual calendar, big date, and the patented zero-reset mechanism. Ingeniously, unlike most calendar wristwatches, when set correctly, all functions pertaining to the calendar instantaneously advance in unison with a single press of the button at 10 o’clock, surpassing the need for an additional tool to set each individual calendar function. With this, the watch is user-friendly and hassle-free for a collector with many timepieces in their rotation. Further, the watch features Lange's patented "zero-reset" mechanism which allows for precise time setting by jumping the seconds hand to 12 o’clock when the crown is pulled out.
