One of my favorite photos of all time. The Valjoux 222 flyback caliber of a French Air Force Issued Dodane Type 21, with the sunset reflecting off its various components.
Serving as tools for flight, these watches have endured a lot of abuse and many overhauls during military service – evidenced by scratches on the movement and mismatching pushers.
Here are a couple other shots from the same session.
