Alessandro Nivola wears an unidentified watch

Billy Brennan, played by Alessandro Nivola, is Alan Grant's protege in Jurassic Park III (2001), the young paleontologist whose theft of two Velociraptor eggs nearly gets everyone killed and then, in a partial redemption, helps save them. He is last seen badly wounded but alive after a Pteranodon attack.

In the river scene Billy crouches at the water with a dark watch on his wrist, a rugged outdoors piece appropriate to a dig-site scientist, but the shot is wide and the light is flat, and the dial never comes close enough to read. No costume credit or watch index records it, so it stays unidentified.
