Casio Digital Watch WS1600H-1A

Inspired by 1990s sports design, the face features two bars and a circle at the top that display three different timers — the 1/20 second stopwatch in a color bar above, the ten-second stopwatch in the bar below, and the one-minute stopwatch in a circular display at the right.

These multi-sports watches are always ready to go, with a 10-year battery, water resistance up to 100 meters, LED lighting, countdown timer, and alarm.
