Arnold Schwarzenegger wears a Seiko H558-5000

Schwarzenegger wears a Seiko H558-5000 as Mark Kaminsky in Raw Deal. The H558 is the watch that earned the nickname 'the Arnie', and it remains the model most associated with his mid-1980s peak. Collectors still pay premiums for clean examples.

John Irvin directed Raw Deal as a mob infiltration story. Schwarzenegger plays Kaminsky, a former FBI agent demoted to small-town sheriff who goes undercover inside the Chicago mafia. It is widely considered the weakest of his mid-1980s action films. The H558 is a hybrid analog-digital dive watch with a titanium case, alarm, chronograph, and 150-meter water resistance, overqualified for organized crime work but worn regardless.

The nickname has outlived most of his later watch choices. When collectors say 'Arnie watch', they mean this one, the titanium hybrid on the largest action star of the decade.
