Thanks Nola.
My '52 BB crystal catalog has the Andrew taking the MX2189 crystal which is listed as 21.8x19.0. I would say that based on the crystal specs that this is the same case as the Andrew but engraved.
Without an ad though, I have to go with Unknown.
unk.
Very nice watch with great engraving.
Unknow for now.
December 1950 ad from the Canandaigua Daily Messenger.
The "CARLYLE". Ad from Bob the Emperor of ads! :^)

Carlyle....nice!
Agree - Carlyle, I'm a bit surprised that this is the only example we have of this watch. I assumed there would be more but I didn't find any.
Nice work Emperor Bob. Hey, wait a minute, we've already ID'd one as an Emperor, you'll need a new 'handle' there good buddy.
Carlyle. Your still the emperor as far as I'm concerned Bobbee.
Finally...I have one too, and can enter it now that it has a name....(I was being lazy)
Carlyle from me. Good match Bobbee
