Cheers mates!!
Im working on a Seiko 7123A, im ususally not doing quartz, they are so unpredictable I think... Or is it I dont know them good enoght.... anyway.
I have oiled all bearings, cleaned, og had to fix a little on the quick set on the date and day.
And now the quick set work, the date and day skifts when I turn th hands 24 hours.
The movment runs fine, and keeps time.
But when is shall shift date and day during the night, the movment stops around 01.30, but the second hand works.
It seems like the movment cant drag the calender work through the shift.
Can somebody pls help me with what the cause is??
