About this Product
The Casio F-91W is a classic digital watch known for its reliability, simplicity, and exceptional value. First introduced in the late 1980s, it has earned a reputation for durability and longevity far beyond its modest price. Its quartz movement maintains accuracy within ±30 seconds per month, and the 7-year CR2016 battery keeps it running for nearly a decade before needing replacement—easily done at home with a small screwdriver. For many owners, that combination of accuracy and low maintenance makes it a daily-wear watch that can last decades with care.
While its resin case and acrylic crystal are prone to scratches compared to stainless steel or sapphire models, the F-91W remains remarkably tough for everyday use. It’s rated for day-to-day water resistance (splash-proof, not swim-proof) and has a legible LCD display with a one-sided LED backlight—functional, though dim in low light. The simple design also makes it highly repairable: replacement straps, gaskets, and batteries are widely available, and online guides walk users through basic servicing.
Casio backs the F-91W with a 1-year limited warranty covering defects in materials and workmanship. While coverage excludes wear-and-tear parts like the band and glass, the warranty terms are transparent and supported by accessible service centers. In short, the F-91W isn’t heirloom-grade in materials, but it’s a long-lasting, easily maintained timepiece—a true workhorse that often outlasts far pricier watches.
