I'm thinking a 1928 Trojan.
The case is marked "Bulova" and "American Standard" with a June 10, 1924 patent date. Its 14K gold filled. The moment is a 15J 10AP marked 1927. 15J is constant with other Trojans but this would be the first Trojan with a 10AP movement. I see these 10APs scattered in the database associated with various models from the 1920s that appear to usually have 10AN movements. So I think its original.
This thing runs. Its definitely showing its age but I got a good deal on it.
Your second Trojan I think Tom, you're not building a horse too are you, Greece has enough problems as it is I think?
Note the "roman" numerals scratched on the movement holder VIII - VIIII - VII. Note that they are the same as the last three of the case s/n? (Yes, I know the 9 should have been IX).
Wow, I covered Greece, Rome AND Troy all in one post! Wouldn't my Latin professor have been proud of me. In my next post we'll talk about the Peloponnesian War!
OH, yeah - 1928 Bulova Trojan
