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!

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.

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

A low cost classic
Bought this for a friend. It really is a great watch, if all you want is something on your wrist to reliably keep great time and last forever at a low cost. If you want a piece of jewelry or a status symbol, this isn't it, but if all you want is a watch that serves it basic intended function this one is the gold standard.

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.

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.
