Jon Favreau wears an unidentified watch

Jon Favreau was five years away from directing Elf and seven from Iron Man when he played Gus Partenza, one of the astronauts on the Messiah crew in Mimi Leder's Deep Impact. Partenza is part of the team sent to plant nuclear charges on a comet headed for Earth. In the outdoor scenes before the mission, he wears a dark watch on his left wrist. It appears to be a simple sport piece. The brand has not been identified.
