The A. Schild 1680 watch movement is an automatic, jewel-bearing rotor movement with 23 jewels. It features a detached manual wind and an ingeniously simple power reserve display. The power reserve display is achieved by transferring the rotation of the barrel arbor to the hand, and the rotation of the barrel to a tiny dial, without the need for a complicated differential gear. Additionally, the movement includes sweep seconds and an automatic function. The power reserve display has a range of 2 to 38 hours, although it should be noted that this range actually covers a run time of only 34 hours, making the stated range slightly exaggerated.
