I haven't yet found a similar enough match for this one. L4 on the case back and movement suggest 1954. 10k rolled gold plated bezel, stainless steel back marked Bulova New York. 17 Jewels, unadjusted Swiss movement 6BL. On the bottom left of the movement is a stamp that is difficult to make out even with a loupe. The first character appears to be smudged or is possibly a squared off B, the other two are a fairly plain XW. Works very well as is. The band is a Speidle.

The Speidel is likely aftermarket replacement. I didn't find any close match either so I'll go alomg with the Unknown classification.
Admins can replace your photos if necessary. send to admin@mybulova.com. There are several useful photo editing tools in the free domain. I use VeiwNX from Nikon. The trick is lighting and focus rght.
I found this add for a "Vivian" , similar but not the same. Searched the name and found few references. The Academy Awards is similar as well. I haven't noticed this particular add in the archive, though I am still new here. Thought I would post it. May help someone out. 1952 Bulova advertisement.
