They are in Massachusetts and have a small but interesting selection and a social media presence (Instagram, Facebook). http://thosewatchguys.com
I can say this about them - I just ordered a vintage Hamilton Thin-O-Matic (Linen dial - totally love them!) and inquired about how long it would take to ship given that I'll be out of town over the holidays and I get an immediate reply.
We'll see how this vintage thing goes - my only other vintage watch is Soviet (assembled in Poland) and so far I can't find anyone who is willing to work on it...
Any feedback on these two guys?
