Hello, I'm new to collecting vintage watches. Read a lot about dials and patinas. Came across a vintage Omega Seamaster that I quite fancy. http://www.ebay.com/itm/222121820056?_trksid=p2055119.m1438.l2649&ssPageName=STRK:MEBIDX:ITPurchases made through these links may earn this site a commission from the eBay Partner Network Would like to ask the experts out there if it's worth $550? There are blemishes on the dial and I'm not so sure if that's a good thing this time. Much appreciated.
