    • Perfect everyday watch
Color: Black Style: F-91W-1
The perfect Watch! Super affordable, accurate, thin, and durable. It wears very comfortably and it’s lightweight so you can barely feel it. It is also super easy to read the time at a glance as well. The light could be stronger but that’s a running issue with Casio. Overall, this watch will get a lot of wrist time. The best everyday beater watch ... show more

I wear this watch everyday. It’s been durable, it only has a few scuffs for how much I wear it and the job field I work in. I love the classic Cassio style, it goes great with any outfit. The functionality is great as well, I use the stopwatch and alarm daily. This is a great watch for everyday wear and for collectors alike. ... show more

    • Must buy watch , just does what you need from a watch.
Color: Black Style: F-91W-1
Love how small and comfortable it is , it doesn't get snagged on thing like bigger watches. It's easy to read for its size. Amazing watch especially for just 20 bucks , the only complaint is the band is small , I'm on the last 4 of holes on the band.

    • Dim light
Color: Black Style: F-91W-1
Great watch for the price. Only downside is light not bright enough to see time in the dark. I have a solar watch and battery dies when I wear long sleeves.

Review Image by Ryan
It's a classic watch that does what its supposed to. It's reliable and keep times well, which this model has earned. The build quality and materials feel solid for a basic watch. It's also surprisingly comfortable and I often forget I am wearing it. The appearance of the watch is fine. It's not a fashion item, but you know what you are getting. The drawbacks to the watch I feel are the weak backlight and that it it's not fully waterproof. That said, the backlight is still usable and in my experience the watch handles splashes and things like showers just fine. Overall I think it's a great value if you want a basic digital watch that will last you a long time. This watch has been around since 1989 and still is a popular watch, and for good reason. ... show more
