Casio F91WB-8A Grey Digital Watch

Casio F91WB-8A Grey Digital Watch

A modern take on Casio's long-running F-91 design, the F91WB-8A pairs a restrained grey finish with a lightweight resin case and a bio-based resin strap. The simple digital LCD shows the time, seconds, date and day, with a 12/24-hour format. Useful everyday functions include a daily alarm, hourly time signal, LED light and 1/100-second stopwatch with elapsed, split and first/second-place measurement up to 59 minutes 59.99 seconds. A February-28 auto-calendar, everyday water resistance and a rated accuracy of ±30 seconds per month keep the specification practical.
