Casio DW290-1V - Tom Cruise - Mission Impossible
This Casio classic sports watch can be seen most clearly during the magic trick scene (watch here).
The Casio watch has a black case, a red line around digital screen, green text on the black case (Electro Luminiscence - Illuminator - Water Resist - 200m). Features include day/date, 5 alarms, stopwatch, light and hour signal.
A cool feature is the Backlight that can be set to flash / light up during an alarm or hour signal.
