Hi everyone,
I got referred to this thread, trying to look for a Seamaster 120. I was told the watch below was not correct - based on what?
What I can think of is that the Omega logo and text should be switched around and the fact that the engraving is too thick. I'm not sure about the bezel. It looks too perfect to be true, but I also don't find it very glossy. What do you think? Anything else that is incorrect?


STAY AWAY FROM THIS, DO NOT PURCHASE

It’s all wrong, but it’s most prevalent on the dial and bezel.

These are known fakes and have been discussed various times in this thread. There’s a lot to go at but give it a read and you’ll start to get a good understanding. It’s necessarily reading for anyone looking for a 120.

Thanks everyone- don't worry I won't buy, was trying to understand everything that's wrong about it. I was curious what part of the bezel was wrong, but will read through more of the pages to understand

As a starting point;

Bezel - look at the pip.
Dial - Seanaster

Seanaster vs. Seamaster is usually the first thing I look for on these.

I've been going further, and now came across this model, listed by a private seller who claims it's from his family and all original. I've been examining the pictures, my only doubt was the seconds hand, but I've read another thread where it was said this was quite common and perhaps service replacement.

Also I'm seriously considering to bid for it, but with so many fakes I'm not sure what's a fair value. Watch has been serviced a couple of years back, but no proof. Appears to be running accurately. Listing price is 2500 but that to me feels way out of hand. Thanks in advance for your advice!

Missing case clamps and screws?

Good spot! I would ask the seller if he is aware that the clamps and screws are missing - perhaps he pulled the movement out when taking pics (why I don’t know) and hadn’t put it back together yet.

Otherwise it looks good to me. Considering it comes with the factory bracelet and correct endlinks, with original bezel and pip, and nice dial with good looking lume- $2.5k is very reasonable these days.

In case they do end up missing - is that an easy replacement part to find?

I would ask the seller first- he isn’t a novice with watches, the quality of his images, the fact that he got the back off and the travel case he has the watch resting on speaks to that

Not too hard, but I don't like it. What else is wrong if it is missing obvious parts? So if you buy it, factor in some service and parts.

Oh it's even this outer ring which is missing, hadn't seen that. The seller doesn't know why it is missing, he didn't remove it himself, and it only went for service a couple of years back. Hmmm.. feels tricky.

possible his watch maker neglected to replace the parts

Sorry I meant to ask - the picture that you shared, is that of an actual seamaster 120?

The movement retaining ring is absolutely not easy to find. A few years ago I had one with a heavily damaged ring and several watchmakers said they couldn’t help. After scouring various sources for months I eventually called Swiss time services who thankfully had one.

Point is, you’ll likely need a full service from an Omega authorised watchmaker to get this piece.
