My Peregrine Chronograph is displaying an incorrect DAY. I can change date, etc; but cannot figure out how to change the day !!! Am I missing something ??

Wind the time past 12 and 12 again (hour hand) and the day should change. You will have to keep winding the watch 24 hours to change the day to the one you want.
If that doesnte work you may have a broken movement.

Many thanks for reply ............ I figured this out this morning - I'd already tried it, but obviously didn't go a full 24 hours Must be the time of year....brain not 100%
