In reply to Thanks Yes it was my concern by William Smith
From database watch and ad examples, this "exact" or a very similar dial spanned at minimum early 1927 thru at least 1929 (in subject watch). This dial is same appx measurements and looks like Wayne's 1928 Executive dial from:

down a ways at
There is, like you pointed out, the 27 Ambassador at http://www.mybulova.com/watches/1927-ambassador-1806 in case w/ 1924 patent date and very similar size dial & case, but different printed tracks.
I was just trying to decide if the dial in the subject watch was likely original, and in which other watches or ads it appeared, and over which appx timespan. Thanks for your help. I'ts a cool unknown watch w/ a nice old dial that was apparently not used for too many years based on what I could find poking around.
