Matt Damon wears a TAG Heuer Link

In Martin Scorsese's The Departed, Matt Damon plays Colin Sullivan, a Massachusetts State Police golden boy who has secretly been Frank Costello's mole since childhood. He climbs into the unit hunting Costello while feeding the gangster everything it learns. On his wrist is a steel TAG Heuer Link.

The Link takes its name from its bracelet, the polished S-shaped links that interlock down the wrist, and that bracelet is the easiest way to recognize one on screen. The example on Damon is a plain steel quartz model with a dark dial, and the film never makes anything of it.
