I've only been seriously collecting for the last three years and have accumulated maybe 70+ watches. Obviously, most sit in the box but still get worn occasionally. but even the earlier reps with crappy movements generally still work. I'm lucky and have a good watchsmith who gets a kick out of my reps and, although I haven't serviced any yet, when they need repair he does it for a reasonable price. I don't think I've spent more than $60 on any one yet. I've only had three crap out and they were easy fixes for him.
I've got watch winders and each one hits a winder for three/four days every month. Maybe that helps.
I agree with Gunnar. I can't see throwing them away. I sort of get attached.
Do I think they have a soul? Hum..............
Do I need to get a life? Hum............
