Arnold Schwarzenegger wears a Casio AMW-320

Arnold Schwarzenegger plays Detective John Kimble in Ivan Reitman's Kindergarten Cop (1990): a hard-nosed LAPD detective who goes undercover as a kindergarten teacher in Astoria, Oregon, to find the ex-wife and son of a drug lord. Penelope Ann Miller and Pamela Reed co-star.

On Kimble's wrist is a Casio AMW-320, the gold-dial analog-digital diver that collectors nicknamed the "Arnie" for its association with Schwarzenegger. It is an affordable, sturdy, under-$100 tool watch with a rotating bezel and a small digital window, the kind a working detective could plausibly own. The watch stays on through both halves of the film, from the violent opening drug bust to the classroom.
