Hello,
I ask you to recap here all references of Omega with cal. 30 T2 and cal. 265/266 jumbo oversized cases in stainless steel (37mm. and over).

I know ref. 2505 and 2603 with a diameter of 38,5 mm., but I presume that other references exist, also before fifties.

I thank you to post your pictures.

 

Ref. 2609.

 

Ref. 2272-3
37,2mm.

 

There are around 30 references that I’m aware of if you include the Seamasters. Cal 37.6, 26.5, 23.4, 25x and 28x in the mix. In addition, many of the early jumbos have no reference number on the caseback, so it makes it hard to identify them but most of their case “styles” get reference numbers imprinted in the later 40’s.
Here’s a REF 2325 from my collection

 

Thank you very much. No limits to calibers (only my mind limits ).

I saw some early jumbos without reference number on the caseback, but with numbers like movement serial number ( i.e. 114xxxxxx).

 

2544 & 2545. Both are 39mm.

 

You are talking about 30 references. Might you recap anything else of those you refer to?

Guys Im desperately searching for a case for my oversized Omega Jumbo 30T2PC. Am I chasing a lost dream? My movement is serviced and ready to go bar a crown. The dial is well worn but thats how I like them. Thank you in advance. Adam
