Jewel count matches. Lisa's 1950 ad for Bowen sure looks "tentatively" good to me.
The crystal corners in the ad may appear "angled" or slightly cut corner, but I'm only seeing that in the top right corner, and think it's the artists rendering. Now I'm off to look for "Bowen" crystal specs. If we have crystal data on "Bowen" and it indicates a cut corner crystal, I'll eat crow...
Edit: I've ate crow before, and it kinda tastes like chicken. I'll chance eating it again for this example.

Snippet from page 104 of the Watch-Craft Crystal Reference Book No. 217 There are many, many pages of Bulova records in this section of the document.
...now if I just could figure out what this means...and if its at all helpful LOL I think I look back up in the beginning of the book for details on size/shape of P2MC207 and/or 4MC207.
Page 30 of same crystal book. Page 74 under shape MC of same crystal book.

Maybe FifthAvenue will update root record with the crystal dimensions...and if they are that of Bowen crystal info, I'll go three ticks. Fifth gives case dimensions, and if I eye-ball the bezel space around the crystal, it sure looks like subject crystal is close to relative dimensions of Watch-Craft size.
