This one of the Field/Military collection watches comes with a dial inspired by a Flieger watch or a pilot's watch, and a nylon strap inspired by the "MA-1 Bomber Jacket" or the jacket of a U.S. Army pilot. Although it is an automatic watch, it’s still trendy with a sporty design and is very durable, just like the military watches.
