Casio CA-53W - Stranger Things - Mike Wheeler

Finn Wolfhard as Mike Wheeler in Stranger Things wears the Casio CA-53W.

The watch has a black resin case, a digital display, and a built-in calculator with small push buttons, making it one of the most recognizable tech-inspired designs of the 1980s and a perfect fit for Stranger Things.

For Mike, the calculator watch highlights his curious and problem-solving nature, subtly reinforcing his role as the group’s thoughtful and determined leader.
