Hi NYCnat. WOW! That is a beauty. This one has been identified on here as the "Albert" model from this ad.
The ad isn't very clear and the dial minute tracks don't match perfectly. The ad is from 1930 and your watch is a 1929, so there could have been a slight dial change between the years. Unless a better ad surfaces "Albert" is the best ID for your watch currently in my opinion. It sure is a nice one.
I don't know. That's a pretty grainy ad, and the subject dial is completly obscuring the 6 numeral, along with some other possible differences in both verticle and horizontal bezel engravings.
I gotta go check out other watch(es) ID'ed as such in the database (if we have any), and check for any other supporting ads.
I'm at two ticks tentative for the "other three Albert" in the watch database, and don't see any confirming second ad, so I'm good with tentative Albert for this watch too.
