In 1914, the new concept of air reconnoissance came into play in the developing First World War. It's application turned from gathering information, into full blown hellish air combat. So the high brass issued extremely accurate pocket watches that were specifically designed for airmen. These pocket watches allowed airmen to know how much fuel they had to burn, and would give them an idea for navigation on distances to targets.  
This is one of those watches with all of the air comissioned marks on the back. What does that mean?  This watch has seen combat time over the skies of Europe, thats for certain.  
 
This Non-Luminous Watch was picked up stateside.  The watch has had a tremendous amount of repair and service work to get it up to the correct running standards.  As usual with the ones we choose, this one has an immaculate dial and the original hands.  Dead accurate timepiece that will most likely run for another 100 years.  
 
Serious buyers only, I would personally be more than happy to share everything I know about these watches via email.  This is an incredible piece of history to put on your wrist.
