Great, affordable watch
This watch is awesome, it's stylish and it works great! It's easy to read, fits great on my wrist, and I like the backlight option as well. bonus points: i accidentally put it through the dryer while I was unwrinkling my clothes, and it came out unscathed!

Very good basic digital watch
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.

Great price Great watch ⌚️
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

How can you hate it?
Looks great, super sturdy, 10 year battery life, so easy to read and fit and feel on it is amazing with useful features like alarm and stopwatch. How can you hate this retro Casio.

Square biz
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.

Casio a great simple and mod fixed watch.
I love Casio watches. I have several. The basic Casio watch are great because they can be modified and last a long time. I am going to modify mine with a NFC tag and update the light. Great reliable watch.

Old faithful!
This is your classic 80's style watch! It's robust, inexpensive, beautifully thin, and feature packed.

Ideal minimal digital watch
Does what it's known for: highly durable, minimal form factor and features, perfect volume chime/alarm, display, only con I feel is the light being very "direct?": like an led is being shone on the left side of the display and doesn't spread evenly to the right.
