1950's Omega Constellation Help Appreciated

MtV

Welcome aboard!

I'm afraid what you have there is a mixture of parts. The case and dial dont belong with each other - my guess is it's a 2846 Seamaster case with the dial of a 2852 Constellation. You're right that the crown is also incorrect, but that's a minor issue in comparison.

Have it opened by a watchmaker and have him take a picture of the movement with the 3-digit caliber number and the 8-digit serial number clearly visible. This will help us determine if it's a chronometer rated movement that might be correct for the dial.

To recreate a "correct" watch, you'd need a 2852 case and crown, plus likely someone to service it while the dial is being transplanted. While it's possible to find those spare parts with patience, do note that this wouldn't make sense financially. If you want a great watch to wear and remember your late father, either have it serviced as is (after all, that's how your dad wore it) or source a correct Constellation case and second hand for it. But if you're intending to sell it, don't invest any money. Just have a watchmaker take movement and inside case back pics, maybe give it a bit of a careful cleaning. You won't get back the amount you'd have to invest to buy the Constellation parts you need.

The case of your watch is from a „jumbo“ reference Seamaster. That also explains why we can see the dial edges in your pictures - the case was made for larger dials.

Personally, that would make me consider a replacement case. That being said: It‘s still your dads watch, so considering this is how he wore it does play a significant role.

If you need assistance with finding a suitable (as opposed to: any) watchmaker let us know. This is a pretty international place and usually there’s someone who can recommend someone good for a service at least in your country.

Wow thanks, so the dial and movement are Constellation circa 1954? Put into a late 60's Seamaster (larger) case?

Could dial and movement have originated in 2652 case?

MtV

Both case and dial are from first half of the 50s. The movement is chronometer certified so most likely correct for the Constellation. I can’t tell you which Constellation reference, though. Since it’s a bumper movement it’s not from a 2852 as I initially thought.

So the jumbo seamaster used a case that had been around since the 50's

MtV

I’m not entirely sure how to respond to this tbh. There are various different jumbo references for Seamasters. This particular one is from the first half of the 50s, and so are the Constellation movement and dial in it.
