1953 Bulova Unknown 21J 8AC with a L3 date code, 10K Gold filled bezel and case back with fancy "wings" attached to the bezel sides, Speidel padded Black Croc-grain strap. I picked this up at a local estate sale, kind of a neat looker, cleaned up nice and running smooth. *Possitive ID update 2-15-12 Nice ad find by Shawn!
I noticed your crystal is hard to find. I found the GS one for mine is the CMX 324-2B. (Though GS lists the CMX 325-10 that doesn't work because the top & bottom & sides are curved on the crystal, but the case has flat top & bottom, with a slight curve on the sides)
