Meaning of T1, T2, etc
Omega used the code T1, T2, etc to show a 'version number' of a calibre.
i.e. the first version of the 30mm calibres was called 30.
The next updated version was called 30 T1. Then 30 T2, and so on.
There was always some small, or sometimes not so small, update to the movement when the changing from T1 to T2 to T3, etc.

Hello all, Please someone explain to me the meaning of the caliber: 30T2SC or correct what I think I already know about this Omega caliber code. 30 indicates the movement size of 30mm. T2 indicates some form of going barrel??? And SC indicates the Secondh...

Sounds like an interesting book, but if I don't find it at the public library I probably won't be reading it any time soon. Of course, I could maybe make a trip to Bienne? Or I could win the lottery. Thanks again to all for the information. Cheers! Sharky
Somewhat perplexed
Opened 30T2 SC Ref. 2179 today (I hope I properly id this wristwatch). Looks great. Having it cleaned, oil, & adjusted. Found inside: mvt # 10.340.028 16J case # 2179-4 According to a mvt # chart I found online this mvt # means the manufacture date is...
Can I
identify my Omega wrist watch by its movement number only? Movement 10.340.023 16 Jewels I thought in was the US ARMY Ref. CK2179 caliber 30 SC T1 or 2. But no US ARMY stamped on case back. Inside Case Reference number is 2179 - 4. Now I think it is eithe...
No 16 J

thanks to Franco and grumio... very well said! Good Hunting Bill Sohne
Tes, thanks for the info...........................
That info is very interesting to me as well - so much that I have added it to my notes on 30mm series watches. Cheers
Copy.
Thanks to all for info and the book ref. (Book added to Wish List.) I have an Omega I'm trying to get to keep time. It loses minutes per day which ain't good (e.g. I thought I was on time for Good Friday dinner, but the wife informed me I was 15m late - I...
A bad position, maybe.
Hello. Some watches work well in some positions and stop or slow, fast in other positions, make sure that your watch is working well in all positions. Good Luck Your watch looks like a US Army Ref 2179 with a 30T2 ? This message has been edited by hoipoll...
Howdy!
Hi hoipolloi, I suspect you are correct. When I get the screw-off back screwed off I will post the numbers I find. NOTE : US ARMY is not engraved on the outside of the case back of my watch - I read in numerous internet postings this common. Inside Omega'...
What you should you is
Hi Sharky. I surmise these are French abbreviations for "Advancement" and "Retardement", non? Oui . Also, can a novice apply a sparing drop of sewing machine oil somewhere to improve 30 T2 2179 operations or better not to? Non, Jamais The only thing you c...
Dankeschön oder danke schön oder wie?
Hey thanks hoipolloi for the advice. I will heed. Will keep stainless steel. Why not? Besides, it feels great and I like it. Copy and comprehend crown lack of Omega marking. This does not bother me. Some think the crown is a replacement because it does no...
Looks good.
Thanks for the pic. My camera will not take close in shots (too bad for me). Your numerals seem somewhat different then mine. What do you say to this? When I get the back off I will (attempt to) date my 2179. Perhaps this will explain numeral deviation? S...
My Ref. 2179...
... has no logo on the crown or crystal, but came with an Omega leather watchband and US-market signed buckle. It was purchased from the family of the original owner, so I have only two explanations for this: 1. The band/buckle is original to 1946, or 2. ...
Nice 2179.
Hi Gator. It's a very nice 2179 you have. Signed buckles or plain ? I am not sure but I assume that it happened at the same time with the crowns and I save some money on that (signed buckles are expensive, you know) Now, back to the topic. Does anyone has...
I like it.
Opened Ref. 2179 today. Took it to get clean, oil, and adjusted --- waiting for an estimate. Got it open and found: mvt # 10.340.023 (according to the info I researched this makes it a 1944) 16 J case # 2179-4 When able will post pic's.

NOT all 2179 and 2384 werer US ARMY....
Hello Everyone... I just wanted to jump in here, I have seen over the years about 2179s and 2384s as US ARMY watches. NOT ALL 2179 ans 2384 are US ARMY. These reference were also sold into the public markets as well. THE US ARMY version of these reference...
Not sure -- now.
Hi and thank you for the extra information on this Father's Day. Based on what you write I must go with this 30T2SC 16J NOT being US ARMY because it does not have US ARMY stamp on the back. And the inside the case, Case Reference is 2179 - 4, i.e. NOT "21...
Ok Sharky409
Hi A few questions... is the watch currently running ?If it is running is it running fast slow ? is it consistent ? Do you have a photo of the movement ? This could sort of help in guessing a typical estimate. Ok now what book are you referencing as the O...
mvt No. 10.340.023
No photo of mvt. Sorry. It is consistently slow. The expensive book from the museum. COPY: 2179 is thicker then 2384. In remarks somewhere in this blog it was stated 2179 civilian version based on ref CK2384 (1941). That is, there was a Ref 2179 civilian ...
Need to know for
sure what the inside case reference is for the Omega Ref. 2384. Anyone know for sure? How does one determine the difference between Ref. 2179 and Ref. 2384. Sharky409...
Correct hoipolloi
Any idea what the difference is in the 2179 & 2384? Does the Omega db have info. on Ref 2179 civilian model? Does the Omega db say anything about Case Ref. Number 2179 - 4? Would you re-glow a vintage Omega, i.e. hands & dial points? Grateful for any info...
Hi Sharky
_Any idea what the difference is in the 2179 & 2384? Bill already wrote about it, I guess, (I don't have a 2384 and don't know anything about it) _Does the Omega db have info. on Ref 2179 civilian model? No, they don't _Does the Omega db say anything abou...
OK.
I won't either, i.e. re-glow. I am having it serviced as you recommended. So the "4" in the 2179 - 4 is a "batch" number. OK. On mine it is written 2179 - 4. I notice it is also written often as 2179/3. It seems Omega has poor records for the 1940's, Unde...
Great info.
Case : round (29 mm dial opening), with screw-in case back This watchstyle - based on reference 2384 - has been delivered to the "U.S.Army" in a limited quantity of 10'000 units, during spring 1945. It bears a "U.S. Army" engraving on the outside case bac...
What is the
internal Case Reference number? What is the mvt nbr? Is US ARMY stamped on or engraved on? Sharky409
What cost
should I anticipate for this service? Your thoughts very welcome. Sharky409
