Val Kilmer wears a Bulgari Diagono

Away from the downtown gun battle, Heat lets Chris Shiherlis sit still for a moment. In the oceanfront apartment scenes he wears a round, two-tone watch with a dark dial on a dark strap, the gold case catching the grey daylight off the water. It reads as a Bulgari Diagono Scuba, the dive version of the same Diagono line that Vincent Hanna wears as a chronograph on the other side of the chase.

Two Bulgaris in one 1995 crime film is a striking choice, given how rarely the brand reached a leading man's wrist back then, and it looks deliberate rather than accidental. The bezel and dial never come into clear enough focus to read the Bulgari signature, so the exact reference stays open, but the round two-tone case, the dark dial, and the dark strap line up with the Diagono Scuba that Boss Hunting identifies in the film.
