I just finished putting back together an old Citizen 8200A movement which was stripped, cleaned & lubed.
My problem lies on the fact that on position "B" of the crown (1st one out where you set the day and date) the day set works like a charm but the date (reverse) does not. It sounds like it gets stuck somewhere and it stops halfway before changing. With some effort I manage to set the date as well but it is far from ok.
In case it matters the date changes effortlessly when advancing by the hour setting position.
Unfortunately I did not test this function when I received the watch so I do not know if this problem already existed before I meddled with the movement.
P.S. I made sure I advanced the time to 10 hours after the date change to avoid any problems.
Any ideas? Thanks!
