·That has a 2500c date wheel, that's all I can tell you . 😁
Wivac, thanks for reply.
I also Found a previous thread & I think i'm now pretty sure that it is 2500c as you say (boy, does that "Archer" know his stuff). I think it could probably do with a service as was new in 2009 (but made in 2008 it seems) & never been opened. I'm just reluctant to service it as I will probably not wear it for a long time due to a new purchase which I cant seem to take off, and Omega want £450 GBP for a service. And it runs well when worn/wound.
