Here's a fun one that I just received.  I got it for a winning bid of $39.99, which I consider a bargain for a neat two tone watch. I've added a nice brown band, and have it on my wrist as I submit this...

 It matches up with one on Watchophilia and an ad for a model called the “Bertram”, but the ad says the Bertram had 21 jewel movements and mine has a 10AN 15 jewel movement.  Lisa's has a 17 jewel movement.  Mine is  running and has the “T” case code, which dates it to1932.  The case number is 1090696, which would date the case to 1931 (which corresponds to the ad for Lisa’s Bertram).  In addition to Lisa's, I found this discussion about a similar watch that has 17 jewels (and a fantastic band) http://vintagewatchforums.com/viewtopic.php?f=31&p=20760 .

Also, the dial on mine is different from Lisa's and the one in the vintagewatchforums discussion, and they are all different from the one in the ad, which has a radium dial.

So, given all of the anomalies, does this suggest there was a different model with the same case with an option to buy the watch for less with fewer jewels?  The ad lists the Bertram for $57.50 in 1931, which was a pretty pricey watch back then!    Anyway, I would appreciate the panel's thoughts and insights...
