As I understand it, a quartz watch is a battery-operated watch. Can those be repaired? If so, is there a kind of a price limit where they are not worth it - for example, a good working watch that would be worth 125.00 in good working order, say a fella could get it for $45.00 is that worth it. Maybe that is a bad example but not sure what it cost to work on one and where the price break would be.
