Man, if you hadn't shown the inside of the case I would have had to question if this was actualy a Bulova.
The engraving is not like anything else I have seen from this period or Bulova.
The engraving down the sides is the only familiar sight for the case.
Mark,
Why is this oval and not tonneau?
David,
Unique eh? I think the engraving was enameled at one time, which Color(s) is the question. 1930 leans toward Black but without an ad to ID the Case who knows?
Darren,
Good question. Case shape changed to Tonneau.
In reply to David, Unique eh? I think the by FifthAvenueRes…
I was wondering about enameling. Finding an example with the colors would be very intersting.
Currently, the closest resemblence to the pattern(s) on the Bezel are found in an ad dated Aug 1928.

interestingly enough the corner and end pattern strongly resembles half of the pattern found on the 1926/27 'CONQUEROR / LONE EAGLE'

Wow, great spot! Lady Lindy without enamel? Very close.
1928 Lady Lindy. . .lacks the fine detail of the subject watch.
