Keanu Reeves wears a Hamilton Khaki King

Eddie Kasalivich is a machinist, not a scientist. He builds the equipment the physicists design, and that distinction matters: when a hydrogen-fusion experiment at the University of Chicago succeeds and immediately draws people willing to kill for it, Eddie's survival depends on his hands and instincts rather than theory. Andrew Davis directed, with Morgan Freeman as the government figure whose loyalties stay unclear until late and Rachel Weisz, in one of her earliest American roles, as the physicist who goes on the run with him.

A watch-spotting site identifies Eddie's watch as a Hamilton Khaki King, the brand's field watch built for legibility and durability rather than prestige, which fits a machinist who works with lathes and drill presses. The watch is not clearly legible in the available stills, so the specific model stays tentative, but a plain field watch is the right instrument for a working character, and Hamilton has supplied film productions since the 1930s.
