Hi,
I am new to watch repair and have mainly been servicing simple eta movements for my own
I have always wanted a chronograph watch and have found a watch based on a valjoux 7750 with a broken case.
I want to put the movement into a new case but the dial is a day date and the movement is date only.
I have sourced all the parts and have fitted them to the movement to add the day function.
The donor watch didn't use a dial washer / foil, do I need to use one now I have added the day indicator?
If I do need a foil, what size and where from?
Thanks very much
Stuart
