Triangle date code, 10A movement. 1926 Trojan?
This is one we seldom see in green (yellow alloy) gold. Nice find indeed!
1926 Trojan
1926 Bulova Trojan. If you aren't familiar with this era of Bulova History.......In 1926 as well as making this watch, Bulova was making a watch called Conqueror, it looked like THIS. Then in May of 1927 this fellow name Charles Lindbergh flew his tiny little airplane non-stop across the Atlantic. To celebrate that feat, Bulova renamed the Conqueror watch THE LONE EAGLE which was Lindy's nickname. After that time the Trojan style watch was renamed Conqueror.

1926 Bulova Trojan is a good match. Love to see the green gold watches.
