Pictured is a WWII piece, the Elgin US Army Air Forces Type A-11, a 16-jewel hacking navigation watch. With a late 1945 serial number, this watch likely never saw combat and its dust-proof case is nearly perfect, as are the dial and hands.
When I received this watch, it had a red second hand, which I can believe came from the factory, but does not match the specification. In this case, since value is relatively low, I sourced the correct hand to replace the original hand. The long tail of the second hand is black and hard to see unless it passes across the hour or minute hand.
These watches were supplied on green fabric. I have the original strap, but in this case, the watch wears a black shell cordovan strap with a period Elgin buckle. I imagine that a pilot brought this watch home and replaced the fabric strap with something a little more snazzy.
