Casio CA-53-WF-1B – Calculator Watch Icon
A true Casio legend, the CA-53-WF-1B is one of the most instantly recognisable digital watches ever made. Compact, lightweight, and unapologetically retro, this calculator watch blends everyday practicality with pure 1980s charm — and remains just as relevant today.
Its slim resin case and strap keep things comfortable on the wrist, while the iconic 8-digit calculator keypad turns this watch into a functional throwback that still sparks conversation. Beyond the calculator, you get dual time, a stopwatch, alarm, and full auto-calendar — proving this classic is more than just a novelty.
Simple, fun, and endlessly cool, the CA-53 is a timeless Casio staple with cult status.
