Mamoudou Athie wears a Casio Digital

Hal Dockins, the young lawyer on Jeremiah O'Keefe's team, sits in a car with his cuff pulled back, and the watch catches the light squarely on his wrist. The crop puts the whole watch in view.

The dial reads CASIO above a small green-tinted display, set in a rectangular digital case on a ribbed metal-look bracelet. The brand is legible in the frame itself, though the screen is not sharp enough to fix the exact model. If you recognize the specific reference, a comment would help.
