Bulova AEROJET from 1967
Just completed restoration, except for the dial. Case is all stainless steel, marked M7. Dial is marked Bulova Aerojet Waterproof. Has a very nice color to the dial, not sure if it is the original color or now has some patina. Hands were replaced with NOS. Crystal replaced with NOS. Added a brown leather strap that is marked Bulova AEROJET on the back; not the original strap, but goes quite well with the watch. Movement is a manual-winding 11ALC, M7 dated, 17 Jewel.
So far, there are no Aerojet ads in the database for this variant (non-automatic, non-calendar type).
