Hello everyone, this is my first time post. I recently got interested in vintage watches after inheriting an Omega Suverän and a 60s Seamaster automatic from my grandfather. This post is not about those watches but I hope to present them in a post in the not to distant future.

Now I'm on the lookout for a vintage Omega chronograph and have found one for sale that I'm interested in. It is a 320 with a stated diameter of a 37 mm. The caseback is stamped with 2381-2.

I found nothing for 2381 in the Omega vintage data base. And no good hits when filtering by the 320 caliber.

When I google 2381-2, nearly all the results are watches that look a bit different than the one for sale. Watches found by Google are mostly very similar to the one in this post: https://omegaforums.net/threads/omega-320-for-critique.6480/#post-75951 while the dial of 'my' watch has a younger look. The dial is very similar to many 2872 specimens, for example: https://omegaforums.net/threads/omega-320-for-critique.6480/#post-75948, but it is a little bit bigger. The movement serial is 18 miljon something -> around 1961.

The first photo is of the watch for sale. Not the best photo but compared to the 2872 above, I 'see' more space between the sub dials and the closest markers, which makes sense for the larger diameter of a 2381.


The next two photos are of the best matching Googled finding. But this watch is described as a 35 mm and the caseback is stamped with 310455.



Finally, my request for information:
- Does anyone know if the production of 2381 watches went on until the 60s and did it get the younger looking dial?
- Or should I suspect that there is something funny with the watch for sale, like it has been put together from parts from different watches?

Also, please point out any errors in my reasoning above.

Many thanks.
Jonas

 

Well . . . I love it! It's beautiful! But I'm afraid I may just add to the confusion. I own this one, which is marked 2278-3 and yours is only the 2nd pic I've seen of a watch with this dial that's not in a gold case? Mine came from Chile, and I love the coffin markers

 

And mine is 35mm

 

The auction ended today and l did not win...

Baz9614, thank you for posting!

vintage omega white dial chronographs are really nice. mine says hello

 

cal.930! pretty!

 

so beautiful

 

Here's the watch mentioned by OP, pictured with a smaller 35mm cousin.

Vertical grained dial with coffin markers are indeed quite special!

 

Note the one marked 310455 is NOT a SWISS made case.

 

Agreed! It's a little on the small side, but I love the details in the markers.

 

Thank You all for posting great information. It really helps to see all these variants together. Personally, maybe I like ErikR's cal. 930 De Ville the most.
