Omega TV Dial Seamaster, cal 1010 water damage

Hello everybody,

While visiting for the holidays, I got to handle a watch that I've chalked up as probably a fake a while back.

As I had the tools to open it, I decided to give it a shot, as I was told that it stopped working after the owner swam with it many years ago.

When I opened it, I saw that it's an omega cal 1010, with visible signs of water damage (some of the screws are rusted / black and gunked up).

The stem can't be pulled as I suppose it's rusted up as well, so didn't force it.

As the watch has sentimental value to the owner, I was wondering if anybody could asses how badly damaged the movement is?

Coud this be fixed with a deep clean?

Would the movement need to be replaced (I read that they aren't very reliable?).

The case is gold plated from what I could see on the caseback and bracelet (20 microns).

As a rough idea, what would be the cost of fixing it? And what would be the value of the watch after it's fixed? and in this condition?


Thanks

Without taking the movement apart it is hard to fully assess the damage, but I've seen movements in a far worse state of repair revived. However, whether it would be cost effective is a different matter. Though as you say this is a sentimental case, that may not be a concern.
