An A. Lange & Sohne timepiece is the ultimate in luxury, especially a model as fine as the Langematik Perpetual. This gorgeous timepiece is made of platinum and boasts a gorgeous silver dial and displays indication of hours and minutes as well as grand date located at the 12 o'clock position and a perpetual calendar and moon phase indication. One very special feature of this timepiece is it's patented zero-reset mechanism that allows the calendar displays as well as the moon-phase indication to be advanced both individually and with one single main push-piece collectively.
