Here's a legendary military-issued 1950s Zenith Pilot chrono manual with a rugged dark bronze dial with light even patina as you'd expect from a watch of this character.
Mega-cool. These were issued to the Yugoslavian Air Force in the 1950s. You can almost feel yourself in the cockpit of a 1950s aircraft somewhere over Europe.
The solid stainless steel case is 37mm across, and 43mm from lug to beefy lug. Light scratches throughout, as you'd expect.
Under the hood is the Excelsior Park high-grade manual 143-6 movement, keeping excellent time. Chrono functions working fine as well.
Strap it on.
