Seamaster Cosmic 136.017

Stopped by the local jeweler with the dog again, checked for any other Omega and spotted this one. I remember seeing it maybe a year ago and skipping over as it had a monocoque case and nothing on the back. I picked it up today to get a closer look. It is indeed a monocoque case but there was something on the back. It was worn enough years to nearly erase the Seamaster script, logo and ref. The crystal is scratched up, I will take toothpaste to it tonight. The gold-plating on the crown is nearly all gone. It's on a 16mm debeers ostrich strap. It has the 613 handwind under the hood as second click of the crown advances the date. I figure it will fit right in with the Seamaster DeVille I picked up earlier. Thanks for looking!

Is the case corroded? Second pic, left side. If so, sweat can get to the base metal and slowly make the damage worse.

Good catch, plating is worn down to base metal at that edge, thanks.

And now that I think of it and from the wear to the crown from handwinding, I'm thinking that wear is from the index finger winding. The amount of wear to clear off the logo would indicate a lot of hand-winding.
