I bought this one blind. No clear photos and no indication of movement or age. I was pretty sure it was a non-Bulova case based on the fact the engraving pattern is like I have never seen and there were no visible stampings on the back. I thought it was likely a "President style" replacement case.. Even so, it looked cool and was apparently green gold.
It arrived in the mail and even in hand I had doubts. Upon opening it, I found the case back is stamped Bulova inside with a serial number dating the case to 1933 with a 1927 Pat. date and 14K Gold Filled. Movement is dated 1929 with a serial number. Movement is really dirty, but with some coaxing, it started to run. Starts and stops, but balance looks good. Watch is mounted on a period black leather band that could very well be original based on style, buckle and how crudded up the spring bars were.
I have no idea what it is besides "All Bulova". Never seen another.
