Speedmaster Moonwatch Hesalite Nylon Strap

The One NASA Qualified.

Hesalite rather than sapphire, because acrylic crazes rather than shatters and NASA would not put glass in a capsule. Solid caseback, black dial, nylon strap.

The Moonwatch is the only watch NASA ever qualified for manned spaceflight, and it has been on every mission since 1965.
