Arnold Schwarzenegger wears a Seiko Hybrid Diver (Arnie)

Three of the commandos in Predator (1987) wear matching Waltham XX011 military watches. The prop department gave them identical wrists. Schwarzenegger got his own Seiko. John McTiernan directed this one, a year before he made Die Hard, and the cast reads like an action movie draft pick: Carl Weathers, Jesse Ventura, Bill Duke, Sonny Landham, and Shane Black, who was there partly to do uncredited script work and partly because McTiernan liked having a writer on set he could kill off early.

The Seiko H558-5000 on Schwarzenegger's wrist is the same analog-digital hybrid he wore in Commando two years earlier. Chunky case, analog hands over a digital readout, alarm, chronograph, and depth gauge all in one. Seiko built this watch for the kind of person who wanted everything on one wrist. Major Dutch Schaefer, leading a rescue team into a Central American jungle where something is hunting them, fits that brief. The watch looks exactly like a tool.

Schwarzenegger was in the middle of his Seiko run at this point: the H558-5000 in Commando (1985), Raw Deal (1986), and here in Predator. Three consecutive mid-80s action films, three Seiko hybrids. Collectors named the watch after him. The Casio and Panerai years came later.
