The F-91WS-4 takes the bones of one of Casio's most trusted designs and adds a splash of colour to the mix. The translucent purple resin case and band give it a casual, relaxed look that stands apart from the standard all-black crowd — without going over the top. At just 21g, it sits comfortably on the wrist all day without becoming a distraction. Water resistant and equipped with a 1/100-second stopwatch, daily alarm, auto-calendar, and a green LED backlight, it covers the daily basics without any fuss. Seven years of battery life rounds out a solid, well-priced package. A practical watch with just enough personality to make it interesting.
