Hi all
I would appreciate members assistance in helping to identifying this watch.
It is 25mm in dia. it has a 10AI 15j movement 3 adjustment. The case is stamped American Standard. with a shield emblem underneath 25 years . Monogram Quality.
it is also marked14k gold filled.
The case is hinged
Lady Maxim? Not sure this shouldn't be 1922 by the serial number, these are murky waters. The watches branded on the dial as LM are quite varied, and we have several listed as 1921 that are the more traditional non-trench type. Possible Rubaiyat? Have we ever confirmed that Rubaiyat models may not have been branded as such? What about a 150?
Shield case begins with 11xxxxx and I have theorized that with these early cases the year is the second number. This applies to those case serial numbers starting with 1 and from this period.
10xxxxx = 1920
11xxxxx = 1921
through to
15xxxxx = 1925
We then see normal case serial numbers starting with the year of manufacture. We also see 1923/24/25 cases start with either a 3/4/5.
Apart from one watch (there may be more) the cross over between Globe and Shield has occured at case serial numbers 1083175 (Globe) 1098712 (Shield)
This is not the cut over just from the records I have researched. So between these two number Bulova stopped using the Globe and started using the Shield. It will be good to narrow this down.
