So I found this watch, an Enicar 1962 17 jewels Gold plated Incabloc Manual. Is it working, however the crown has a slight balance and gets loose so the hands can be moved accidentally. Therefore needs repair. Overall the watch seems to be in a good condition considering its age except that bite in the back case.
My question is if it's worth buying it and repair it, if can be repair? Maybe and advice of how would make this a good acquisition to worth repairing it.
