My newish speedmaster still have it on
Been wearing it for years, never noticed, but its not on my 60s era seamaster. Maybe the glass has been changed on the other one?
Yeah I missed it on my 32mm Seamaster, but i found it with my camera.All my vintage Omegas (not that many, just 3) have the Omega logo on the crystal.
They're not easy to see and quite difficult to photograph, unless you have a macro lens assisting you.
