Hi All,
I'm working on an old Heuer with a 555.115 movement in it.
I am able to advance the calendar wheel when the crown is in position 2, but the calendars does not change automatically when the watch hits midnight (or ever).
I've tried both letting the watch run for 48 hours, as well as just swinging the arms for a full 24 hour cycle with the crown.
Does anyone have any insight on this issue?
Thanks!
