Looking for a case for a movement 751

Purchased a lovely omega constellation 751 with a 18ct gold dial unfortunately the seller scrapped the case and bracelet which was all 18ct . heartbreaking but happy I could save the movement for it to live on. I’m looking for a case I’m fully aware that I’m probably never going to get something original like it was originally in. I like the idea of a C shaped case with a pitted bezel if that makes sense one with character and not smooth possibility gold capped . if anyone knows any reference numbers with would fit this movement would be much appreciated so I can keep an eye out but I feel I might have to wait for something with a non working movement . Thank you in advance

Pity the scrapper didn't realise the dial is solid gold as well.

Good luck with finding a nice case.

Do a search on the caliber and you will find watches. Just check to see if the reference number is listed

Make sure you get a case with extra height for the day/date mechanism.

Finding the right dial diameter can also be tricky. I speak from experience since I am also on the lookout for a 751/752 case.

ChatGPT said 168.029, 168.041 and 168.019 had caliber 751.

Hahaha I won't tread on your toes as I'm from the UK 👍 thanks for the heads up on the extra height for the case been looking for a while with not much success I don't really want to be spending £800-+ lol just for a case I guess it's just a waiting game for a some what good case with a knackered movement and hopefully it goes for less then £400. Good luck on your search

I appreciate that I totally forgot about chat gpt lol tho I don't know how reliable it is I did just search the case numbers and they all look good and a possibility what they'll fit. Just gotta keep an eye out now

It does a good job with simple searches like this, but I checked the references before posting just to be safe.

By the way cases are same, crystal accommodates the height

Finding a case for these seems futile to me, with each watch melted, rest of the whole watches can elevate using the parts, so its better to seek a 168.029 with a seized movement, or sell to a 168.029 owner with dial damage etc.

Depends on the case ref. For most of the 55X/56X this holds true with the different hand pipe heights. The stem pipe can also be off. 75X is a thicker movement with the day/date mechanism and usually a flat date wheel. 55X/56X has a domed date wheel and dial to match. Front loaders tend to be more interchangeable than snap back.

Interesting enough, I noticed that some of the late 1970s/1980s cases use plastic movement rings. Same as the quartz calibers of that time. Quartz watches typically have flat dials without the dome. It looks like movements and cases from this time period might be interchangeable. Which goes against the purist in me.

Dials have the most variation. Last year I laser etched a bunch of blanks. The dial is often what holds the movement in place with the case clamps offering counter pressure.

I am getting quite a collection of worn out cases and dials. There are half the listings there was a year or so ago, the prices are up and some of the stuff is bordering on unusable.

You are correct, even for 1000+ cal C-Case's the cases started varying, but what I mean is: for 168.029 specifically crystal is the difference

Yeah I also noticed that as soon as gold prices doubled, even exorbitantly expensive cases were scooped up and now there are gold linen dials inside steel cases in the market 😁

168.029 is a very nice case and I do really love the bezels on these. There are some on eBay between £800 and £1700 not really seen any selling . in the sold listing not much either a nice one I’ve missed sold for £500 as non working which would have been ideal for the case and then maybe getting the movement working and selling. What would you recommend the maximum price would be to spend on something to put my movement in would it make it a little more valuable because of the 18ct dial ?

Most Omega's are cheaper than their sum of parts

So let's say your unit is worth 450 - you spend 200 on a case, 100 on crystal, 50 on crown, and assembled it yourself for free, once you auction it, it will fetch 550 at best, and you could sell it for 650 out of auction, a futile effort overall even if everything goes right and labor is free

Better to sell it for 450 to someone in need and move on

Do the flat dialled Constellations powered by a 564 have domed date wheels?
(C cases, 168.018 etc)

168.029 GC with 751 with fluted bezel which is 14k I think, would look great with your dial, which looks like C case dial to me.

I only have a 564 movement, no case or dial. 564 and 565 share most parts other than the auto mechanism and that is mostly the adjusment info on the bridge. Obviously the finish on the chronometer is what makes the difference.

565 SM300s seem to have flat date rings.

My older connies are 561 without quickset. I should look at my C case sometime. Notes say that it is a 168.017. I got it around 30 years ago. Should clean it sometime. The other connie from that era is a piepan.

I have flat dial dynamics, but those do not have date.

75X have additional wheel bosses and tracks for the day machinery on the upper plate.

With the advent of the C case, Omega moved to flat dials for the first time on a Constellation. (early versions were 561, then later 564)

They continued the dome dials with the existing references, including the 168.005 and the 168.004 and its replacement, the 168.010 (again, early versions were 561, then later 564)
With new references later in the 60s the 168.016, day date, and 168.018, date only, (cal 564) Omega employed flat dials as they did with the monocoque 168.015. (cal 564)

Given the profile of the dials, I suspect that they would need to adapt the date ring to suit by also making it flat.

(Note: pie pan dials weren't available for the C cases or .016/.018/.015 but were still available on the 168.005, .004/.010 and 168.025 at the same time that Omega moved from dome dial to flat dials)

I also thought of the .016 but if the hands are original then I’m definitely leaning towards a .019/.029 C case for the original case reference.
