On my A7753 i cant change date anymore via button at 10 o clock. Button cant be pushed it looks like it is stuck. Is this big deal for repair or it is easy fix?
I am in EU and i have my own watchsmith, i just asked becouse i can tell him if the procedure is easy fix for him or not. He is very limited with own time....
The issue might not be with the movement, but the pusher on the midcase. I love complications, but they ultimately are more possible points of failure. Your watchsmith will have to pull the movement and see where the issue lies.
