Help finding reference ID? 30T2 waterproof case / engraved lug

Good evening everybody,

I just acquired this watch and couldn't find lots of info about the reference. It has a caliber 30T2 and it measures 35mm without crown, 18mm lug to lug. The number on the caseback is just above 10.000.000. The number on the movement is just above 9.180.000 which should place it around 1939, correct me if I'm wrong. What strikes me the most is the number 146 under the top left lug, almost matching the 145 on the inside of the caseback. The caseback presents itself without reference number and a spiral in the center. Can please someone help me understand a bit more about this piece? Many thanks.

Cesare

It's kind of difficult when you cover up the two main pieces of evidence we have. BTW, I think both numbers are "145", so the case matches.

We do not have catalogs from the 1930's listed on the site if a case reference is what you are looking for.

Why did you hide the serial number?

^ this
Gator has nailed it.
Numbers sometimes are not cast perfectly and may lead to errors...
The watch is perfectly fine and is most probably a reference CK 2169

You are probably right about the "145" on the back of the lug, I looked at it again and it's probably an imprecision that made it look like a 6 from a bit of a distance. Could this watch be assigned? The other CK 2169 linked above does not have the engraving on the lug. Also as I understand the CK 2169 was produced from 1941 according to Omega website. The case number and movement number dates it further back, here are the pictures with full serial numbers.

Now that I can see the full serial numbers, I have a concern that the case and movement might be from different watches.

The movement is pretty early for a cal. 30T series, maybe as late as 1940. The earliest 30T’s are in the 8.9M range and we know these are from 1939, even though Omega’s own dating charts show this as 1936 or so. Note that there is a typo error on the entry for 9M serial numbers on this chart.

The case would seem to date from 1943, well within the production range of Ref. 2169.

I think the only thing you can do is wait until Omega again accepts requests for archive extract later this year.

@mac_omega should be around soon to straighten us all out. After all, he wrote the book on these.

Hope this helps,

I have checked 2 of my CK 2169 which are unmolested NOS finds.
The case serial ## are very near the number of the OP.
The movement serial ## are in the range of 9.26xxxx, so not too far off the OP´s movement which is 9.185...
Furthermore all parts of the OP´s watch look consistent/commensurate (conditionwise) and the whole "package" seems to be reasonable.
It has an unrestored dial, original hands and even has the original crown which is a positive hint...
IMO the watch is perfectly fine.
I wondered if the EoA (when available again) would tell differently.
