I have held onto most of my quartz watches which are primarily complicated chronographs- ETA 251.xxx and 252.xxx are the most fun, but I have most of the ETA's worth a shit- no G-10's and like that (min cost for me to collect is $17.00), not that there's anything wrong with them. A couple favorites: A few classic CD's (my favorite is the Birds of Prey Warhawk Missile Mission Commander 100 XL

I love that chick), Sector 300 M classic "No Limits" screw-down diver-chrono, old Rotary, Original Zodiac Oceanaire, (recently picked up at a pawn shop for $85 because the guy was sick of looking at it) an Invicter moon-phase, Hammy 3 hand / date whose name escapes me, original JDM Seiko LCD chrono/alarm, and a Pulsar LED.
