your lawyer did you a favour .If everything checks out OK & after waiting for the experts to comment, I think you got yourself a fine piece there.Our Omega expert Mr. Graham should be around soon to give you his blessing - or not! I have been on the hunt for a 300 on & off for some time but was told by a dealer recently that an original in good condition without replacement parts were hard to find. Enjoy & thanks for sharing your adventure Fernando
Thanks Richard, for this this well-written story of yours finding this vintage Omega SM. I thoroughly enjoyed reading it! Best regards, anaesdoc

when you least expect it. I guess I should start looking in antique stores more often. Regards, Richard.
Hi this looks a classic Watchco-type Seamaster 300, i.e. made with replacement Omega parts (labelled Mar2000) which means that the only part really from the 60's is the movement. Watchco and others scavenged the movement from a DeVille or other, and then build a watch with all Omega replacement parts.

But I can tell you it is a great looking watch. Thanks for taking the time to tell us the story. It's nice, isn't it? Running into people who know what they are selling. Ruckdee
