Help identifying reference of vintage Omega chrono

Hey WC fam, can anyone tell me the reference for this Omega? I was told it has the 321 caliber. Considering adding to the collection, but want to do some research first.

Thanks!

I recommend caution. Check out WatchBase.com. I look up caliber 321 and 321B and the hands are wrong for what they have on that movement.

I don’t know much about Omega watches, but think you should do as much research as you possibly can before pulling the trigger on that one.

Where are you buying this from? That dial looks suspect.

A local shop that specializes in vintage watches. I used him to service a few if my watches. So I know/trust him. Suspect how?

omegaforums.net is full of knowledgeable and helpful people. Especially on vintage.

I am no expert in vintage watches, but by looking at how other vintage watches have aged, the tachymeter indices look artificially aged by friction, which should not happen naturally. Judging by a pic can be deceiving, but personally I'd stay away from it.

Possibly a Frankenwatch. As others have said, do your due diligence and don't pay over the odds.

Look up Omega 2451, first sold in the 40s with several variants. The movement number will allow you to look up the year. (Cal 321 was previously 27 CHRO C12 T2).

There are examples with that handset. It's an odd one, several handsets appear to have been used that you wouldn't associate with Omega now. Looks legit to me.

Vintage is so tricky!!! The advice I've always heard is to buy the seller not the watch. In other words, it is crucial to buy from trusted and reputable sources especially when buying vintage.

This is a very popular/hyped vintage style (mechanical sports chronograph) from a big brand.

Supply is low, demand is high. That is likely to attract fraudsters.

Even if the seller is honest, it's entirely possible he/she's been duped.

That's why I limit myself to lesser known vintage brands, ideally ones which went bust decades ago, which are less likely to attract fraudsters (Universal Genève being an exception which proves that particular rule). Or really unpopular models.

The omegaforums.net suggestion is a good one. Even after consulting them I'd proceed with extreme caution.

I second the Omegaforums.net. Those guys are crazy smart about vintage Omegas. If that is a legit watch with a 321 movement I would grab it in a heartbeat!

The seagull ST1902 movement have that exact dial layout. Not saying that this watch have a ST1902 but it sure would be easy to make a replica with that movement.

... but this is probably not a ST1902 as the 12h dial at the bottom is pointing straight up at the 12h marker. If it was a ST1902 it would be shadowing the hour hand 😬

Thanks, All for all of the info and suggestions. I also reached out on Omegaforums. Will see if anyone responds. Honestly, the watch isn't on my list. I saw it in the shop while picking up another from service. (Whats that shiny object in the window?). So I live without it.

I can ask him to open the case so I can see the movement. He's obliged the request in the past. @MedicMike I agree, if it's a true 321 I may have to snap it up.
