Part Request - Omega Seamaster

Hi All,

Recently acquired this lovely vintage seamaster which i have done quite a bit of work to (you can see the ETA replacement movement in picture 2).

I bought the watch without a caseback but i now have the hellish task of trying to track one down. The only issue i have is i cannot find a model reference for this on the Vintage Omega Database. If anyone can provide more details or knows somebody that may have one i would be very grateful!

Its always the simplest answer Completely overlooked that as an option! Dont suppose you know anyone with a case back
