Val Kilmer wears a Polar Accurex II

Through the armored-car robbery and the downtown shootout that anchors Michael Mann's Heat, Chris Shiherlis wears a blacked-out digital watch, the same field kit the rest of Neil McCauley's crew carries. Boss Hunting identifies it as a Polar Accurex II, a heart-rate monitor that in the mid-1990s was still mostly the preserve of serious athletes, which makes it an unusually deliberate piece of kit to hang on a movie thief.

In the surviving frames Shiherlis is in tactical gloves with his suit cuff pulled over the wrist, so the watch never resolves on screen. The identification follows Boss Hunting's reading of the film rather than a readable dial, and it stays at Possible. The film's far more famous Bulgari is on the other side of the chase, on Al Pacino's Vincent Hanna, while Shiherlis keeps a quieter two-tone Diagono Scuba for the dress scenes.
