Jeffrey Wright wears an Omega Seamaster

Jeffrey Wright plays Dr. Rutledge in Source Code, the controlled, slightly weary scientist running the program that keeps sending Colter Stevens back into the last eight minutes of a doomed train. This frame catches him leaned in close to a microphone in the control facility, glasses down his nose as he talks Stevens through another loop.

His wrist is not in view in this particular shot, but the watch database watch-id.com documents Dr. Rutledge's watch in the film as an Omega Seamaster. Since the watch is recorded by that source rather than read off this frame, treat the Seamaster as a solid lead rather than a dial confirmed here, and a clearer wrist shot would pin the exact reference. If you can place the specific Seamaster, please add it in the comments.
