I thought this might be a good forum to find out more about my Omega Seamaster that I recently inherited from my father. It was purchased sometime between 1955-1965 when he received his first big promotion at work. Anyone able to help identify the actual model and year? Thanks in advance.

It's a great early Seamaster chronograph with a caliber 321 movement from the late 50s or early 60s as you indicated. It is gold or gold-capped I assume. A photo from the back would help determine that. The serial number on the movement will provide a more accurate estimate of the manufacturing date. Wonderful heirloom. You will get the most information if you have someone open the watch (it should be a screw-in caseback) and post photos of the movement and the inside of the case-back, clearly showing all numbers (serial number and reference number).

As a guess, the reference number may be KO 2907, but that's really just a guess (see below) and there may be other similar references. In any case, the reference number will be clearly indicated inside the caseback.

 

Would appear to be 2886 as a ref. See https://omegaforums.net/threads/vintage-seamaster-321-reference-s.50866/

 

I concur it might be a KO 2907.

At first glance the crown looks strange and the chrono second hand doesn't look matching. I don't think the pushers are original.

 

Thank you for your reply. I shall see if I can a watch smith to remove the back for a photo. The outside case is worn down to the point that nothing is legible.

 

Wow. A 321 Seamaster.

Can this be called a moonwatch because it has the cal. 321 movement?

 

I think the early Seamaster chronographs are often undervalued. Beautiful watches, but they didn't make it to the moon, because it lacks of liquid water there.

 

Arent there seas on the moon? Like the sea of tranquility?

And for speed, i have not heard of a fast lunar rover.

 

Yes, maybe I should look for other brands, that had "Moonmaster" models.

 

Isnt there another brand that claims a moonwatch?

But to get on-topic, this is a nice specimen of a Chronograph seamaster. Curious if at that time the chronograph functions can be performed underwater.

 

The inside back.

 

The movement

 

15.14m serial? circa 1956/7 then. OVD has it as a 1958 onwards piece but there are many inaccuracies and omissions on there.
