Hi fellow forum members,

I am not at alla familiar with old Omega Analogue Quartz watches and movements. I dont know why but all of a sudden i recently got a little interested in buying a Seamaster 120M Quartz. Never have been interested in these at all before. But now to the point, i have found one for sale and i need advice and help in what to do. The watch looks like it is NOS on the outside and that is a big plus, the sticker on the case back is still there. The big minus is that the seller thinks that the original battery is still fitted and and from the pictures i have seen it looks like it has leaked at some point. It can be seen on the dial, the calendar wheel and a little on the hour hand. The seller says he does not know if it works and sells it as it is. Im 99% sure the battery acid has destroyed the movement. He asks 340€ for the piece. Is it possible or even worth to fix it? Should i buy the watch?

So the movement doesn't work?

Well with that dial damage, hmm.....probably won't be worth the cost to fix. Value would be only in parts. I think you should be able to find one that works without any major damage fairly easily next time.

The seller says he doesnt know it it works and sells several watches just as they are without any guarentees. He thinks its the original battery fitted from 35+ years ago! I dont think that is a good sign of the movement working considering the battery leakage. I have seen the exact same NOS dial and hands for sale so that could be fixed. I think i could make this watch look like new again cosmetically. The biggest problem is the unsure future of the cal 1337 movement and if this watch is worth all the work and money. I dont even know if there is anyone who can repair it?

Well, those NOS dial and hands....are they actually NOS or service parts?

Anyway just think about it, you have to buy those parts and then fix the movement. Not worth the costs and the sanity.

Do not know if it is worth it or not but this aint 35years old Renata battery. This is newly produced becouse 30years ago standard was differend. It was not called 394 or 395 but it was 2 digit refererence.

Here is oldest example of Renata battery that I have....

Indeed that is not the original battery. The battery shown is a mercury free silver oxide battery (you can tell as it has "0% Hg" on it), and those didn't become widely available until fairly recently. I think Sony was the first to widely make mercury free batteries, and that was back in 2005. Renata didn't make them until 2010.

@ext1 I dont know what counts as NOS parts or service parts? The set is still in a sealed factory stock card as seen below. NOS?

Those look like new service parts, rather than true old stock...

How can you tell that these parts are new and not NOS?

Because nothing about them appears to be old. They look exactly like the service dials and hands that are still available from Omega and can be bought right now.

What makes you think they are old?

I automaticaly thought they were old stock because the watch is from the 80’s. I dont know much about watches and the belonging parts from that era and forward. Im only trying to learn from you people in this forum and you are helping me with information 👍

Same- I don't see how they are NOS old, because I don't see any patina on it. And even if they were old, well, it's all not that attractive..

It is not the same thing if the parts are new. You guys have convinced me not to buy the watch so im not going to. It is simply not worth the time and effort. I just have to wait and hope that another better example turns up
