Timeless, Reliable, and Incredibly Affordable!
The Casio F-91WB Series is an absolute classic that never goes out of style. I’ve been wearing mine daily for months now, and I’m consistently impressed by its reliability, comfort, and value. The retro design is simple yet iconic, and it’s the perfect watch for anyone who loves a clean, minimalist aesthetic. The digital display is easy to read, even in low light, and the alarm and stopwatch functions work flawlessly. It’s also shock-resistant and water-resistant, which makes it a great all-around, everyday watch. What really stands out is the battery life—it lasts forever! After months of daily use, the battery is still going strong. The band is comfortable and fits well, and it’s also adjustable, making it suitable for all wrist sizes. For the price, you really can’t find a more practical and reliable watch. Whether you're using it for sports, work, or just day-to-day wear, the Casio F-91WB is a fantastic choice. Highly recommended!

Quality for the price, Useful features, Passes authenticity check, Third-party modification support
This really is a great little watch for the price. Casio watches aren't exactly top notch fancy timepieces made to catch the eye, but I personally think that's what's great about it. No gimmicks or bulk, just a watch that does what it's made for, and does so beautifully. It passes the standard authenticity check of holding down the bottom right button until "CASIo" appears on the screen, and doesn't show any signs I can see of being a dupe or fake. The backlight doesn't really do much, but in a pinch (e.g. complete darkness) it'll help you see the watch face enough to know the time. You can actually get third-party modifications done to get a better backlight if you'd like, but of course that's not included with the standard watch itself. The watch can do standard 12hr and 24hr time cycles, has an alarm (which can also just beep once every hour instead of going off at a set time), a stopwatch (which resets once it goes past 1 hour due to the limits of the display), and keeps time quite well so far. I've only noticed a fraction of a second delay, which could have just been user error. It also makes it quite easy to reset just the seconds by cycling through the mode screen, then pressing the right button on the main watch screen, so fixing it if it does drift is a breeze. The watch strap is good for what it is, not anything like a super solid high quality metal strap, but what you'd expect from a flexible watch strap. It doesn't feel like it'll easily scratch, rip, or expand, but also feels flexible enough to hold itself comfortably on your wrist. I've already dropped it multiple times, with no signs of any issues, so I'd say that counts towards its claims on durability too. If you just want a watch that works, won't die on you the second you drop it, and has simple creature comforts like an alarm and stopwatch, this is hard to beat, especially for the price, and massive market for third-party modifications that Casio watches are practically known for at this point. If you want, you can seemingly get anything from a better backlight to an inverted color/sparkly screen. Heck, you can even 3D print custom replacement cases and bands for it if you want! To sum that all up, if you need a watch, and you don't want anything flashy, get this watch. It'll do more than keep time, and even if you were to lose or break it tomorrow, the cost of a replacement or repair is a drop in the bucket.
