I have a few CWC G10 quartz watches including four fat boys from 1980. Two of these are quite rare as they are the navigator versions with the date.
Recently, a Precista from 1982 which is also a fatboy stopped working with a circuit board problem. From what I understand, the circuit boards are virtually impossible to get hold of.
So with the other fat boys in mind, is it best to leave them running or is it best to take the battery out if I am to protect these watches for the future?
I wear a 1994 Navigator as my daily watch along with other younger models but just a bit worried about the old ones!
