11153059 is the movement serial number dating the watch to approximately 1947/1948. This watch was cased by Dennison in the UK so you will not be able to find a true reference number like you would on the caseback of Swiss-cased Omega.
Perhaps they call it "military" since it was likely produced shortly after WWII...
Yep, thanks guys, just what I thougt.
But over all and for what it is it looks rather nice in my eyes?
I didn't notice that the "ref" was the serial 😵💫
Military = BS...... marketing attempt..... kind regards. achim
Completely agree! Many watches have a design similar to those issued by the military around the same era. Without MoD/NATO codes on the case back or solid provenance, these are not military issue. I will say that some servicemen and women did wear civilian watches in the service or to theatres of war. But that doesn't make them military issue either.
You have a good watch in nice condition. Enjoy!
