Gaten Matarazzo as Dustin Henderson in Stranger Things wears the Casio F-91W.
The watch features a black resin case, a digital LCD screen with stopwatch and alarm, and a slim strap that made it one of the most iconic budget watches of the 1980s, perfectly matching the retro world of Stranger Things.
For Dustin, the Casio adds to his quirky and practical personality, grounding his character in the everyday realism of small-town kids caught in extraordinary events.
