Hi Folks,
Would welcome any help that you can give regards my late fathers Omega Constellation. Bought in the PX stores on the US airbase in Bermuda mid to late 50's.
The sweep hand is missing, and am not sure that the crown/winder is either original or genuine.
Doubly confused by the plain back with the words "Seamaster" and "Waterproof"
The script on the front includes the word "chronometre" and below 6 o'clock the words "Swiss made"
Should I organise service and photography of the internals as a starting point. Maybe sourcing a sweep hand if that is relatively straightforward?
How likely am I to be able to source a crown and/or a back and are the costs prohibitive to the watch value
TIA
Hope my photos are sufficient atm. Am based in the East Midlands UK

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.

Jewellers cloth will gently shine the gold cap and polywatch, or similar, will clean up the crystal - and then just wear the socks off it!

If you post where you live, someone will be able to recommend a competent watch repairer who can service your watch at a reasonable cost.

Nice watch

Simon Freese or Joe Horner

Both in the UK, but might have to ship

Crown is still available, but modern are gold plated. Original were gold filled or capped

Nice gold capped case, and I like the specs of patina on the dial.
I’d say get it serviced and enjoy it in memory of your father.

If you want to go the route of a correct case for the watch, even though it doesn’t make financial sense, feel free to drop me a PM. I might well have a spare 2852 case here somewhere.

Personally, I think I’d leave it as is, have it serviced, wear it, remember my dad and smile. 😀

It's going to need a bit more than just a service, looks like the second hand pinion is either broken or missing entirely.

I am in lust. The only thing I do not feel for is the gold coloring. On the other hand I really love project watches. The dial however really makes this watch.

That's good to know. Currently runs well and keeps good time
