Are you using "the magic word"? It's a lot to ask for free, my friend. I'll just say that I'm not in love with any of them. The nicest one is the first one. However, the hands are all rusty, and that gives me concern about the movements. The rest are all later 1980's mechanical or quartz watches and are not yet collectible. gatorcpa
Man, I wish you could clean up this post a bit. Maybe organize the listings or at least give me a short summary of what you like and don't like about each one. As it stands, it's hard to go through multiple listings/pictures without any context. Do some of the work so I can at least figure out what you're looking at please. I'll echo the comment about avoiding quartz. Probably a bit less against the 80's mechanical given everyone has their own budget, but it's generally better to save up and buy a better reference than purchase a "weaker" watch hoping it will hold value.
1st is the best but the hand corrosion is an issue at that price. The 2nd is very tired for an 80’s piece 3rd is Quartz so... yawn.
Agree with @Foo2rama and @jaspert but need to see photos of the movement of the first watch. I am no authority on Seamasters, though. Think you will get more responses if you post in the vintage Omega section rather than this Open Discussion one. And yes, you should clean up your post first and share your own thoughts about which ones you prefer and why.
A couple of years ago I would have probably bought one, now that I know a little more I wouldn't buy a watch without seeing photos of the movement first.
