The Kienzle 089/50 watch movement features a jewel-bearing rotor and utilizes a sophisticated excenter self-winding mechanism with just one gear stage. It is equipped with an easy-to-operate rotor lock and a fixed mainspring, as well as a friction clutch on the pawl wheel. It should be noted that the Kienzle 089/50 is part of the Otero family of calibers, which sometimes resulted in different designations for the same caliber. The movement offers automatic functionality, a sweep second hand, and a date function that can be set by adjusting the time between 20:30-24h.
