{"product_id":"casio-f-91wf-cloth-band-digital-watch","title":"F-91WF","description":"\u003cp dir=\"ltr\"\u003eThe 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.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe 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.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003ePower 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.\u003c\/p\u003e","brand":"Casio","offers":[{"title":"Black","offer_id":45267754352706,"sku":"F-91WF-1A","price":45.95,"currency_code":"USD","in_stock":true},{"title":"Blue","offer_id":45267754385474,"sku":"F-91WF-2A","price":45.95,"currency_code":"USD","in_stock":true},{"title":"Green","offer_id":45267754418242,"sku":"F-91WF-3A","price":45.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0014\/6158\/3938\/files\/2026_09_Casio-F91W_Black_index01.jpg?v=1790438174","url":"https:\/\/windupwatchshop.com\/products\/casio-f-91wf-cloth-band-digital-watch","provider":"Windup Watch Shop","version":"1.0","type":"link"}
