I know very little about watch movements but there was certain watches where you should never manually changed the date between 1 and 3 or something like that.
With one of my watches I did change it around 1:30 when I was first putting it on and winding it.
From that time on the watch would never automatically change the date until about 3 AM. Since I'm asleep then I just never cared that much but apparently a watch maker can fix that fairly easily.
Apparently I had messed up the mechanism somehow.
