Harrison Ford wears an IWC Pilot's Watch

Dr. Paul Rhoades rests his arm at a desk, the cuff pulled back to reveal a black pilot's watch. The dial shows luminous Arabic numerals, a triangle marker at twelve, a date window at three and a large onion crown, the classic flieger layout.

The watch is an IWC Pilot's Watch Mark XV, reference 3253, identified by the watch database watch-id.com and reportedly Harrison Ford's own piece given his long history as a pilot. The flieger dial in this frame lines up cleanly with the Mark XV, so the identification is well supported.
