I'm looking for a decent mechanical watch under $50 and having a hard time. I've been looking on eBay for a while and it seems nothing good has been coming up. Any tips on what i should look for and how to find good watches on eBay? i've mainly been looking at Seiko's and Bulova's. Please keep in mind I have a small wrist (6-6.5" :-d), so nothing too big. Thanks for any help.
