Omega military watches
Omega's vintage database names three wristwatches made for armed forces and one aircraft chronograph. The US Army watch of 1941 and the Royal Air Force watch of 1942 share one movement, the 30 SC T2; the RAF watch of 1952 has the 283. We hold Omega's parts lists for both.
All three from Omega's vintage database.
The four references in Omega's records
The reference is stamped inside the caseback. The CK prefix is steel.
| Reference | Name in Omega's database | Year | Calibre | Case | Water |
|---|---|---|---|---|---|
| CK 2179 | US Army | 1941 | 30 SC T2 | Stainless steel, screw-in back | 3 bar (30 m) |
| CK 2292 | Royal Air Force | 1942 | 30 SC T2 | Stainless steel, press-in back | 3 bar (30 m) |
| CK 2777 | Royal Air Force | 1952 | 283 | Stainless steel, screw-in back | 3 bar (30 m) |
| LA 304 B | Aircraft chronograph | 1932 | 39 CHRO | Aluminium and brass, 82 mm dial opening | None |
The three wristwatches are listed on a leather strap. The LA 304 B, with its 82 mm dial opening, is not a wristwatch. Type any reference into the reference lookup for the full record.

Collectors attach military stories to many more Omegas. Only these four are named in Omega's own database. Anything else is a lead until a factory record names it.
The calibres inside
30 SC T2. A hand-wound 30 mm movement with 17 jewels and a centre seconds hand, marked 30 SC T2 on the plate. Omega's GF 620 catalogue lists 74 parts for it and gives the 260 as its base. Omega's database lists it in 10 references, 1941 to 1951, including the US Army and the 1942 RAF watch.
283. The later 30 mm with centre seconds and 17 jewels. Omega's GF 620 catalogue lists 88 parts for it. Omega's database lists it in 19 references, 1943 to 1956, including the 1952 RAF watch.
Every part has its Omega number in the parts finder. The serial on the movement gives the year band in the serial number lookup.
Is yours one of them?
Three things have to agree: the reference inside the caseback, the calibre on the movement, and the record. A CK 2179 or CK 2292 should have a 30 SC T2; a CK 2777 should have a 283. Omega's database does not record issue markings, so an engraving on the back proves nothing on its own. Is it real? covers redials and swapped movements.
What it's worth
A military Omega is worth what the same reference with its correct calibre has actually sold for: use the “What they sold for” link above, not asking prices. What's my Omega worth? explains the method.
Is your military Omega right?
The reference, the calibre and the dial have to agree. Six photos and the weight, and I check them against Omega's own records and put it in writing. Nothing to pay until I confirm the photos can answer it.

Questions people ask
Which Omega watches were made for the military?
Omega's vintage database names four: the US Army CK 2179 of 1941, the Royal Air Force CK 2292 of 1942, the Royal Air Force CK 2777 of 1952, and the LA 304 B aircraft chronograph of 1932. Collectors tie many other references to armed forces; those are leads until a factory record names them.
What movement is in an Omega military watch?
The 1941 US Army CK 2179 and the 1942 RAF CK 2292 both have the calibre 30 SC T2, a hand-wound 30 mm movement with 17 jewels and a centre seconds hand. The 1952 RAF CK 2777 has the calibre 283, the later 30 mm with centre seconds and 17 jewels.
Can you still get parts for an Omega military watch?
We hold Omega's own parts lists for both wristwatch calibres: 74 parts for the 30 SC T2 and 88 for the 283, each with its Omega part number. The parts finder shows them.
Is the Omega aircraft chronograph a wristwatch?
No. Omega's database lists the LA 304 B of 1932 as an aircraft chronograph with an 82 mm dial opening, an aluminium and brass case and the calibre 39 CHRO.
How do I know if my Omega is a real military watch?
Start with the reference inside the caseback and the calibre on the movement: both must match one of Omega's records. Omega's database does not record issue markings, so a mark on the caseback on its own does not prove anything.
