We should be prepared...
Hi Simon,
Hi Bill and all the others who are interested in 30 mm Omega chronometers.
This is an interesting find... And there is no doubt about the authenticity as it is well documented by Omega.
As we knew already for the EARLY 30 mm chronometers (in simple watch cases which were also used for the non chronometer version):
ref. 2254 with "SCREW on" back, CENTER second
ref. 2244 with "PRESS on" back, CENTER second
we see here:
Ref. 2192 with "PRESS on" back, SUB second
I think we should be prepared for a "missing" Ref. XXXX with SUB second SCREW back to appear...
I am curious how long we have to wait... 
And who knows?
Perhaps there is also a missing Ref. XXXX for the screw back 2410 with SUB second... ??
Never say never when talking about vintage Omegas...
just my thoughts
Erich

Hello all, Firstly apologies to anyone who follows other Omega forums as you may well have seen my wittering on about this watch on them, but someone on the Timezone forum suggested that I post here to reach a different collection of Omega enthusiasts so ...
You've heard the adage, "One man's trash . . .
. . . is another man's treasure"? You found treasure ;-) . . . As for replacement cost, I'll leave it to the more experienced Omega collectors to venture their opinions by private message; while it's perfectly alright to ask for opinions, any discussion o...
Interesting watch Simonr..... first time I have seen a Pre-Rg ...
Hi Simonr That is the first time I have seen a Pre-Rg chronometer that was not a sweep second model. The few that I have come across were is 35 mm steel screwback with 30T2SC movements... here is my extract , from 2001 from John at Bienne... " Dear Bill, ...
Movement number disparity
Hi Bill, Cheers for that reply - that's a really nice watch that you have, I've seen a couple of military watches with the dark dial. I was interested to see that although the production date on yours is later than mine and so is the case number, for some...

Wondering what the difference..
.. between the 2192 and the 2244 might be. Hard to imagine the factory would take the effort to reduce the casing by ~1mm just because the subsec. version is a fraction thinner than the SC movement? During WWII Omega exported a large part of it's producti...
The Ref 2192 case could well have been...
Hi Ben, yes, it is an interesting thought you have there... There are 2 explanations which may be likely: The Ref 2192 case could well have been the predecessor of ref 2244 and the case remained the same size, but was equipped with a center second movemen...
More Pictures as Requested
Hello everyone, It's really exciting to hear more info and postulation about the watch, it's also very interesting to hear about other similar Omegas from the 1940s. Nobody else seems to have heard of that case reference either so I'm pleased to have brou...
Please take measurements...
Hi Simon, Please take measurements of 1) diameter of the case (without the winding crown) - best taken between 10 and 4 o´clock... 2) thickness of the case - (please try to measure the metal part only, without the crystal - is not easy...) 3) distance bet...
Measurements
Hi there, Good news - I've borrowed a digital caliper from one of the engineers at work and have made the following measurements. They're pretty reliable, except B and D because I couldn't get the jaws of the caliper in past the bevelled surface to make a...
This is great!
Hi Simon, thank you very much - you have made a great job! Much appreciated... BTW did you receive my private message? kind regards Erich
What do they tell you?!
Hi Erich, Glad to have been of service - have they told you anything useful? I didn't get a PM from you, feel free to send an email instead if that's easier. sboreeves at gmail dot com. BFN SR.
I have compared it with my ref 2244 ...
Hi Simon, hi all, thanks to Simon´s precise measurement I have been able to compare the dimensions with my ref. 2244 case and I must say - given some tolerances in case production around 1940 - it is virtually the same size and other proportions (tiny dif...
after comparison..
.. with a ck2244 from 1948 I arrive at the same conclusion as Erich, there is virtually no difference between the 2192 and 2244 dimensions. Funny, was half & half expecting the 2244 snap-on back to be slightly more bulbous (because of the SC-movement), bu...
Your...
Hi Ben, thank you for chiming in... your comment is much appreciated! So it seems as if we "cracked the nut"... BTW your example looks very fine indeed - have you changed the dial or hands? I do not recall exactly how it looked when you sent me a picture ...
jolly good..
..Erich, always much appreciating your input. And very nice to meet Simon's little known ref.2192 here. Concerning the 2244: no, nothing was changed, although I have an attractive Rg work ready to be 'plunged' in. Still looking for a suitable 'chronomètre...
I think...
Hi Ben, I think I know what you mean with the 23,4 SC - I had one on my radar just recently... was it on the "bay" ? I decided not to buy it because of the small diameter, but I recognized the same case design like a small brother of 2244... Kind regards ...
Simonr..... thanks for all the effort...
HI Simonr I have to scratch my head and say this has got to be the only forum on the net that would get this detailed on a vintage Omega... You have found the right place to talk about this uncommon Pre-Rg chronometre... So what are your plans for it goin...
Plans for the future
Hi Bill, Yeah - I don't know of another watch forum where the discussion gets this detailed. It's kind of funny because on the first forum where I posted about the watch, the consensus was that it was just a run-of-the mill Omega and not worth bothering a...
Here's a theory...
"During WWII Omega exported a large part of it's production via Portugal - wondering if this was the final country of destination?" My guess is probably not. I've received some documentation from Omega saying that some of the "U.S. Army" watches (Ref. 217...
another question for the experts regarding the rg's
do all the rg movements have the precision regulater or do the earlier ones have the normal regulater as seen in the above watches. the reason i ask is that my local auction house has a 1947 Omega described by them as a 30T2SCPG. it doesnt have 'chronomet...
Maybe they have..
Maybe they have misread (shock absorbing system) PC for PG Graham? If a movement picture shows the Incabloc-spring on the balance-pivot and no micro-regulator, well then you know enough: no Rg chronometer version... cheers, Ben.
PC often is ...
Hi Graham, Yes, Ben has pointed out the facts: PC often is mis-read as RG or PG... The easiest way to determine is the balance cock: the chronometer movements did not have a shock absorber! kind regards Erich...
