Notes
detached manual wind
On the predecessor with two date jumpers the date can be advanced by setting the hands back and forth between 20:30 and 24h. Here the hands must be set 24 hours to change the date. Hard to understand, since the single date jumper was easy to design for the quicker date setting.
