    • 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

    • 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.

It's a little smaller on my wrist than I realized it would be but I like that, but it's nice, easy to operate. Light is green and doesn't illuminate the entire digitizer but you can still see what you need. Cool little classic Casio square.

I love this watch!! It's old school, it lays flat on your wrist so it doesn't snag anything, Its lightweight, I don't care that it says "men" I'm a girly girl and I wear this watch proudly! I don't care that people think it's "cheap" it's great! I would choose this all day every day. Flashy doesn't necessarily mean better! Better sometimes comes in forms of a casio F91W edit to add photo and to say, i have been wearing this watch for a few months now and it's still perfect, I bought some bands for it cause that rubber one that comes with it is a no from me. Also if you're gonna buy the bands and change out please take this advice, use a push pin to get the original little metal bar out. ... show more

    • Very good basic digital watch Very good basic digital watch

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
