Is it possible to buy reproduction or NOS case backs for 105.012.65 ?
I see that e-bay etc has loads of 145.012 “new” backs for sale, mostly from Japan.
I mean the solid back, not a spiral winder display case.

Are you sure they are 145.012 and not 145.0012 service casebacks?

It’s the modern version of the 145.012 as Omega changed their numbering system to add an extra 0.

Effectively if your 145.012 needs a replacement caseback, this is the correct Omega service item. O do not believe there is an equivalent 105.0012 caseback

Thank you David, very helpful and instructive. I see they are advertised for “321 watches”. Do you know if the 145.0012 caseback would fit a 321 in a 105.012 case (CB and or HF). I realise the internal code would not be correct. Pity they only come as single bezel (for 65 models)
