Chow Yun-Fat wears a Heuer Night Diver

Quentin Tarantino has acknowledged borrowing the undercover-cop-among-thieves structure of Ringo Lam's City on Fire (1987) for Reservoir Dogs, and the debt is plain when the two are watched together. Chow Yun-Fat plays Ko Chow, an undercover Hong Kong police officer infiltrating a jewel-theft gang while his personal life comes apart: his girlfriend wants to leave, his handler pushes him deeper, and the thieves he is betraying have become real friends. Lam shoots it with the street-level intensity that marks Hong Kong crime cinema of the era.

The watch on Ko Chow has been identified as a Heuer Night Diver, a pre-1985 Heuer dive watch from before the TAG merger, when the brand's divers were plain steel tool watches. That identification comes from a single enthusiast source, and the watch is not clearly visible in available stills.
