The F-91WF takes Casio's longtime F-91 digital and puts it on a cloth band instead of the standard resin strap. The band is made from recycled PET fibers, chosen to be lightweight and comfortable while staying scratch- and stain-resistant enough to move between everyday wear and outdoor use. It's available in three colorways: Black, Blue with a light blue accent, and Green.
The case measures 38.2mm by 35.2mm by 8.5mm and weighs just 21 grams, built from resin for both the case and bezel with a resin crystal up front. The cloth band fits wrists from 145mm to 215mm. Despite the low weight, the watch carries a full set of digital functions: a 1/100-second stopwatch measuring up to 59'59.99" with elapsed, split, and 1st-2nd place timing modes, a daily alarm with hourly time signal, a green LED backlight, and an auto-calendar that accounts for 28-day Februaries. Timekeeping displays in either 12- or 24-hour format, alongside date and day.
Power comes from a CR2016 battery rated for approximately 7 years of use, keeping accuracy to within about ±30 seconds a month. Water resistance is rated for basic water resistance, suitable for splashes and rain rather than swimming or submersion.

Casio is a brand name most people are familiar with. Founded in 1946 in Japan as Kashio Seisakujo and reestablished as Casio Computer Co., Ltd. in 1957 - they’ve made everything from the world’s first all-electric calculator to synthesizers, cameras, and more. Of course, they are also famous for their watches, which include G-Shock, Pro Trek, Edifice, and other tech-forward brands. The Casio Vintage line, as the name suggests, celebrates their earliest digital timepieces. Always fun and irreverent, these fashionable watches are affordable and a great addition to one’s watch box.
