Kind of a vague question, but being fairly new to the watch circuit, I'm really digging the vintage Omegas. I kick myself daily for having not picked up one that was for sale on here a few years ago. With that said, where do most of you guys find vintage watches like that? I have no idea what to look for in regards to condition/pricing on Ebay, and just wonder about the authenticity on Ebay in general. I don't see many pop up on here anymore for sale, and always prefer a trusted source to a general auction site or pawn shop.
