I never saw the complete watch I am afraid - only the bezel was offered on ebay. The seller listed the dimensions so and they matched close enough to what I took with a micrometer so I took a chance. Looks like ebay no longer has the listing viewable or I would pull the photo. I didn't have much luck even finding a substitute until I started searching for "Skin Diver" as that is what they were called in the 60's and 70's.
Here is the photo I took a few days back when I posted it in the thread, she's plenty beat-up but its become my daily driver none the less
