Hello to all and thank you in advance for your time and help. I wanted to ask if it would be possible for someone to let me know which would be the period correct hands and crown for my watch? I am planning on having it serviced, but I would like to take the hands and crown after I source them, for my watchmaker to replace. I don't believe that the hands are original, as I have not seen any Omega with those hands. The crown is definitely not original as it is not marked. I sincerely thank you and appreciate it.

It will be easier to answer your question if you give the 4 digit reference from the inside of the case-back. I have a guess, but since you've already opened it, it would be easy for you to provide that information. Also, I can't really tell from the blurry photos if the dial has lume dots or not.

Hands will most likely be dauphine, lumed or un-lumed, depending on whether the dial is lumed or un-lumed. The tip of the minute hand generally extends to, or past, the outer end of the applied markers, to overlap with the minute track.

Thank you very much for the details. I truly appreciate it. I uploaded a pic of the case back. If these are the ones you are asking for they are 2869. Nothing is lume on the dial. Thank you once again. Very much appreciated.

unfortunately that is the wrong case-back. I think your watch may be a 2657 or 2576 with a swapped back.

Well, this is one of the most frankened watches I’ve ever seen.
Main case - probably 2846/2848 ref
Movement/dial - probably 2576 ref but hard to say (can’t read movement cal)
Caseback - 2869 ref
Hands - none of the above
Crown - none of the above

I guess you can choose which ref you want it to be and source the rest of the parts? 😀

Thank you for the feedback. It is a cal 342. Any idea what would be the closest to original caseback, hands, and crown? Thanks to all once again.

Your watch is all about that black dial. Take your time and no need to make it 100% perfectly original. Get her serviced, a set of hands and crown and enjoy the thing. It's a 1950 watch for chrissakes. Bound to have been worked on a few times and if the case back was switched it's not so bad. Could be the original one was all screwed up, or a watch maker resurrected an old watch with spare case back, hands and crown.

With a 342 inside, ref 2576 could be the right one. I think I recently saw a spare case for sale on ebay.

You could source 1950s crown and hands which match the style of your watch, but if some parts are mismatched anyhow is it really worth the trouble and expense?
You could enjoy it as is.

I’ll just note that the crown and hands look like they’re from the 1940s, and they look pretty nice so could be useful for the restoration of a 1940s watch.
The crown looks very similar to those found on Longines screw back cases from the 1940s aka “sei tacche”, and I wonder if perchance measurements might make some of those interchangeable across brands. At any rate I know someone who needs one for a Longines.

I appreciate all of your feedback and recommendations. If I replace the crown and hands, I will reach out to you about my hands and crown for that restoration. Thanks to all once again.

Ranfft shows hand sizes for the 342 as, 1.40 x 0.65 / 0.15mm, length will depend on the dial.

Crown would probably be a typical cloverleaf, tap 10, tube size dependent on the case, usually 2mm or 2.5mm.

I wouldn't bother trying to "fix" the case, it is what it is and aside from paying for an extract from Omega, really no way of knowing what it's supposed to be.
