The A. Schild 1189 watch movement, utilized around the 1960s, incorporates a manual wind mechanism, sweep second function, and a date feature. Although the specific details regarding the date setting of this movement are not explicitly mentioned, it is stated that with this movement, the hands must be set 24 hours to alter the date. The predecessor of this movement had two date jumpers, allowing for date advancement by setting the hands back and forth between 20:30 and 24h. This design choice in the A. Schild 1189 may appear less intuitive compared to the easier-to-design single date jumper found in its predecessor.
