Hi,

I was wondering if anyone could comment on this mid case which is in my collection. It was originally from an Omega service centre.

I think it is a Seamaster 300 straight-lug CK2913, but I don’t have the case back or bezel to test. I’ve attached some photos with a caliper to show some rough dimensions.

Thanks.

 

It could be from a SM300 2913/14755 or 165014

 

Thanks for the advice. I didn’t realise that there were different variants of the straight lug SM300.

Is anyone able to compare any measurements to confirm which model this may be?

Thanks,

Roddy
