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.

Amazing Watch for the Price + [Makeshift] Button Repair Help
There's nothing bad I can say about the watch. Seriously. I'm a 16 year old kid (you know how reckless we can get) who has had this for I think over a year now, and I can honestly say this thing is REALLY DURABLE!! *How durable* you ask? I wear this thing to school nearly everyday, never having to worry about it. Yes, that means I travel with this thing very often. At school I sometimes even abuse my watch in front of my friends by slapping it on the table with full force to show them that they DO NOT wanna get slapped by this thing (it's just a joke; I would never hurt anyone unless there is very good reason since I'm pretty passive, but they're now aware I have a makeshift weapon with me at all times). I went to Cambodia last summer for a whole month, taking it across the ocean with me, swam in saltwater with it, and traveled most of the country. Surprisingly the airport security all 8 times said nothing about my watch, as it is related to being the official Al-Qaeda watch... something which is a fun fact to tell people. This thing is *still* going strong. It's clear as day to read, with very minor scratches on the face of it. The scratches are not even noticeable at 2 feet away from my eyes (even after the abuse)! The light it has is very long lasting as well, and is bright enough that you can use it as a very makeshift flashlight for things that are very close to you by facing the light away from you and pressing the button for it. It has helped me find light switches in the dark many of times. For settings things, it's very very easy. You may only need to look at the manual probably 2-5 times before you remember everything necessary because it's just so simple. If any buttons are broken it's a pretty simple fix as well; here's what I did: 1a.) Unscrew the thing on the back if you have the right kind of screws. If not, look for them on Amazon. They are I think a -2 Phillips. 1b.) Take out the screws very carefully and put them somewhere they won't be lost. They are very small, hard to handle, and easy to lose. 2.) Gently take out the rubber thing that covers the internal edges. Feel around if you don't see it right away, you will eventually. 3.) Grab a pair of small scissors, meaning the tips of the blade can fit into a small space. 4.) In the watch there are Signal Connectors, which look like small arms coming from the middle edges of the actual machine. 5.) Simply bend them perhaps 45 degrees toward the actual machine using the scissors as pliers. Make sure the button does not lay under or over the Signal Connector, only to the side of it where it can be pressed. 6a.) Repeatedly press the button time to time to test if the function of the button is restored. 6b.) Adjust the angle in step 5 as necessary. You want to bend the Connector to the point it doesn't always touch the Receiver (the thing that actually performs the function of each button), or you will have a frozen watch. 7.) When the button finally works again after some toying around, put the rubber thing back in, pressing every corner back into place, and then screw the case back into place very tightly. 8.) Drop the watch in water before you wear it to ensure you won't get electrocuted. The alarm has gotten me up most of the times, and I'm not a light sleeper. Although I'm also nowhere near a heavy one. The inaccuracy can seriously vary... once it was off by a minute in a week. This week it is only off by about 7 seconds. Really, just sync it weekly and you should be fine. The watch is very good if you just need a very good idea of what the time is. Thanks for reading! I would definitely recommend this watch and perhaps will buy it again if the dang thing finally breaks!!
