The Junghans 683.10 watch movement features a jeweled rotor consisting of 23 jewels and operates on a detached manual wind mechanism. Notably, it incorporates an ingeniously simple power reserve display, where the rotation of the barrel arbor is linked to the hand and the barrel's rotation is reflected on a small dial. This eliminates the need for a complex differential gear. Additionally, the movement includes several functions such as automatic winding, sweep second hand, and a power reserve display ranging from 2 to 38 hours, although the actual run time is closer to 34 hours, making the stated range slightly exaggerated. The Junghans 683.10 movement was introduced around 1955.
