Mine were these .... *PICS*
I'm still enjoying my "New" Bumper.
But I've spent most of the day starting & monitoring long running batch jobs.
A chrono would have helped me estimate run times better ( well I like to think it would have )
I guess I should have worn one of these ....
I found some Info about my Bumper .... From the Museum Catalogue ....
First OMEGA model with date in window. Calibre 353 with rotor, set-in helical springs, gilt dial, polished riveted hour markers, luminous Dauphine hands, gold window at 6 o'clock, water resistant steel case with polished bevelled bezel, protruding case middle and polished cambered lugs, reinforced crystal and screw-in back with O-ring gasket. (CK 2627)
So by pure chance I have bought the first Omega Model with a date window ... cool or what !
