Case dimensions: 27mm (not counting crown) by 33mm lug tip to tip. Crystal measurements and other details to follow. Supporting 1930 ad doesn't mention two-tone gold case, and dial configuration is different, but it's a starting point. EDIT June 5, 2014: The 1930 Ambassador ad mentioned above has been replaced with an August 26th, 1931 ad from the Spokane Daily Chronicle.
The raised bits on the horizontals are square on the subject watch and the Ambassador ad's but rectangular in the Fleetwood ad's. Between that and the jewel count I'm going with tentative Ambassador until we get an ad showing a 2 tone Ambassador case.
EDIT: I forgot to mention the 2 rows of engraving on the horizontals also match the Ambassador.
In reply to Ambassador by mybulova_admin
I'm bringing this one back into the discussion.....now looking at all the adverts we have, I do not actually see an adverts which shows or describes the Ambassador as two-tone case, only the Fleetwood.
We have a number of averts that show other two-tone watches next to the Ambassador which is only shown and listed in a single white gold color.
I'm pushing this one back as a Fleetwood, based on the only adverts we have for this case is for the Fleetwood.
That's a good point. No ad which says two tone. However how are we going to explain the:
Two rows of engravings on the subject watch and one on all (clear) Fleetwood ads.
The differences in the sizes of the of the raised bits DarHin point out.
the outside area of the Fleetwood horizontal bezel is not engraved.
The jewel count differences.
If were gonna review, I'll vote for unknown, but it sure ain't Fleetwood... :)
