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.  
 
It's always so wonderful to find one of these pieces, no matter the condition it is in.  Suprisingly, we were able to find one thats even hard to get than its non-luminous counterpart.  Theres not enough room to give a full history of these watches, but they only made Luminous Omega Mark V's for less than a year before they discontinued them.  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.  
 
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.
