Worn by: Martin Sheen as Captain Benjamin Willard
Reference: Seiko Diver
Brand: Seiko
Army Captain Benjamin Willard wore the Seiko ref. 6105, a chunky steel dive watch with an asymmetrical case and a 4 o'clock crown that was actually worn by U.S. troops during the Vietnam war. Francis Ford Coppola's legendary and notoriously trouble-plagued Vietnam war epic contributed two storied timepieces to watch-enthusiast culture. The model lives on today as the ref. SPB153 from the sporty Prospex series with a 42.7mm steel case, automatic movement, and military-green dial and divers' bezel.

Worn by: Marlon Brando as Colonel Walter Kurtz
Reference: Rolex GMT Master
Brand: Rolex
Renegade Colonel Walter Kurtz wore a Rolex GMT-Master ref. 1675—a style no longer made by Rolex, with a GMT hand and cyclops lens but a plain, stationary metal bezel rather than the familiar bicolor "Pepsi" bezel. The actual watch that Brando wore as Kurtz in Francis Ford Coppola's Vietnam war epic eventually sold at auction for nearly two million dollars, cementing its status as one of cinema's most valuable timepieces.
