Just wondering if someone could enlighten me on what the 2 om's on an omega constellation stand for. Many thanks.

|Sorry, just looked it up on Google and found it stands for Or Massif or solid gold in French.

More of a rugby guy myself. We ( Leinster ) are playing your neighbours ( Montpellier) next week.

I believe it means that the dial is solid gold (alloy obviously).

Thanks Dan s. The whole watch is 18ct Solid Gold.

Right, that would usually be the scenario, gold dial in gold case. I was just pedantically talking about the OM SWISS MADE OM, which specifically refers to the dial. The case will be marked separately.

Sorry, I did not understand the alloy bit. Good luck.

By that I just meant 18k for example. I don't think it's ever 24k gold.

Hello @peterkirk01

Your watch is somewhat intriguing.
I saw your WTB thread and didn't want to derail that - and since you discuss your watch here I thought I'd ask the questions in this thread instead.
What does it say inside the caseback of your constellation and what is the cal and the serial number on the movt?

As far as I'm aware, solid gold Constellation cases are just that - solid, i.e. one piece, including the medallion.
You shouldn't be able to lose the medallion off the back of a solid gold Connie. (whether it's Swiss, French or British made)
If it's British (or French) I wonder if it was a special order to have an alternative medallion put in place instead of the observatory?

I hope you don't mind me repeating the pics here that you posted in the WTB thread for folk's info and to further the discussion.

No problem whatsoever. Because of the OM on the dial i assume it is a French cased watch Or Massif. I will open the case back and get more details. Thanks

That's great, thanks

OM dials also appear in British cases - the dials and movts were supplied by Omega to be cased locally, in gold, to avoid heavy import duties on precious metals.

I can't quite see - are there any hallmarks on the lugs (two hallmarks on separate lugs) - if not, it's likely it's not a Swiss case.
The French tended to put a hallmark ( eagle head for 18k) on the caseback, the Dennison or Shackman (British) cases often only had hallmarks on the inside.

The dial itself is a bit of an uncommon anomaly in a 168.010 - these blocky indices are usually only found on the later flat dials of the 168.016/018 but do appear on earlier gold, deluxe, .010s

Thanks for all the information. I only just bought the watch and it is to be delivered this morning. Really looking forward to getting it.

well, the big S is for Shackman.
The 5 in 168.5004 is the british designation number (French would be 3)
33,XX puts the movt around 1971, which is quite late for a car 564 but not unheard of
