Bill Paxton wears an unidentified watch

Bill Paxton wears a steel dive watch as Chet in Weird Science (1985). The close view shows a steel case with a black dial, a dive bezel and a steel bracelet, the look of a Rolex Submariner, a fittingly macho pick for the military-mad older brother. I can't read the dial to confirm a maker, so it stays open. If you know it, or want to guess, say so in the comments.
