Clint Eastwood wears a Rolex GMT-Master II

Clint Eastwood directed and stars in Space Cowboys as Frank Corvin, the team leader and navigation specialist who designed the guidance system that's now keeping a Russian satellite in orbit. Tommy Lee Jones, Donald Sutherland, and James Garner play the rest of his crew, all former Air Force test pilots who've spent forty years waiting for the phone to ring.

Corvin wears a Rolex GMT-Master II, the watch Rolex developed in 1954 in collaboration with Pan American Airways for their pilots flying transatlantic routes. The dual-timezone function, tracked via a rotating 24-hour bezel and an independent GMT hand, was built for people who needed to know what time it was in two places at once. For a pilot turned engineer who's about to fly a Space Shuttle mission, the GMT-Master carries the right associations. It's the watch that went around the world with commercial aviation in the 1950s and '60s, which is exactly the era Corvin came up in. Eastwood has worn Rolex in his personal life for decades, so there's a chance this is his own watch rather than a prop department selection, but either way it fits Frank Corvin's combination of no-nonsense competence and old-school style.
