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

Awesome everyday watch Awesome everyday watch
Color: Black
Style: F-91W-1
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.

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.

Good watch for the money. Poor night light function.
Color: Black
Style: F-91W-1
A nice watch for the money. It's comfortable and does the job. I returned it due to the poor design of the light to see the time at night. It barely puts out any light. Might as well not even have it.

Very good basic digital watch Very good basic digital watch
Color: Black
Style: F-91W-1
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.

I bought the Casio F91W as a reliable timepiece for work, and it has been perfect. It's lightweight, comfortable, easy to read, and keeps accurate time. The battery lasts a long time, and the classic design never goes out of style. Great value!
