The Kienzle 051/02A watch movement, utilized in timepieces from approximately 1960, is distinguished by its implementation of a pin-lever escapement mechanism. Additionally, it features an indirect minute hand friction clutch on the barrel, which is noteworthy for its simplicity and effectiveness. An innovative aspect of the Kienzle 051/02A movement is the integration of a single part that replaces the setting-lever spring, yoke, and yoke spring. The early versions of this movement were also manufactured with a pointed staff. This movement offers a range of functions, including manual winding, sweep second, and date indication.
