Excellent casio watch, it charges with solar light and interiors light, it has stopwatch until 60 minutes then star from minute zero. Hour hands and minutes hands with lume, it last around 17 minutes maybe a little more, the digital display has good light.

Bought this by accident. It was in my cart when i bought something else. But im glad i did it!! Watch is awesome. Solar charging easy old school to read no frills watch and it looks great. The hands are glow in the dark but tou can set the digital to read out time and it lights up. Its the perfect size. Its a casio so it will last longer than i will this is maybe my 5th casio in the last 20 years and all are still kicking. ... show more

    • A must by for any Casio watch collector
Style: AQS820W-1AV Color: Black
The Casio AQ-S820W is the kind of watch that quietly does everything while asking for nothing in return. It looks rugged without screaming “tactical,” keeps perfect time, and shrugs off daily abuse like it’s a hobby. Solar-powered, comfortable, and loaded with useful features, it somehow makes me feel both punctual and prepared for an unexpected hike, power outage, or extremely serious grocery run. Classic Casio reliability at its best—no charging cables, no nonsense, just a watch that shows up every day and gets the job done. Casio is just the best value in watches. ... show more

    • Incredible value
Style: AQS820W-1AV Color: Black
Looks great! Unbelievable for the price, just don’t expect a fine watch. I own the previous version, which is also great. I just don’t especially like the way it looks. It looks like a watch for a little kid. This watch looks like it’s for a grown up. Great beater/travel watch. If you break it (not easy to do!), or if you lose it, it’s not the end of the world. Best cheap REAL watch out there. The only reason I’m giving it 4 stars is because it’s a pain in the neck to set. It’s actually a 4 1/2. It’s not supposed to be a dress watch or a precision Swiss (or even Japanese) watch, but it’s worth way more than the price would suggest. ... show more

    • Great everyday watch – tough, solar-powered, and super practical
Style: AQS820W-1AV Color: Black
The Casio AQ-S820W Series is a solid analog-digital combo that I really like for daily wear. It's lightweight, durable, and has that classic sporty look with the resin band and big face. The Tough Solar charging means no battery swaps ever – just light exposure keeps it going strong. World time, 5 alarms, stopwatch, countdown timer, and 100m water resistance cover everything I need without overcomplicating things. The dual display (analog hands + digital) is easy to read at a glance. Only minor nitpick is the backlight could be brighter in low light, but overall it's reliable, comfortable, and great value. Perfect for work, outdoors, or just everyday use. ... show more

    • Very cheap and plasticky. Try to buy it on sale (yet, you still may be paying too much ?)
Style: AQS820W-1AV Color: Black
I do own 2 other Casio watches, and I do like them, rugged, tough, look nice. But I Cheap'd out buying this one as it was Solar powered, was curious and wanted to try it out. I'm sure the solar charging works (?) just fine? Idk. Cuz this really is a case of "you get what you pay for", it is cheap, it is very plasticky, and the band and clasp is also plastic, maybe the worst band I've ever had come on a watch. Sad. Mistake #2 was beleaving the description when it says the watch uses a 22 mm. watch band. It Does not, incorrect info. It takes an 18 mm. But I am not going to buy one for it now, as it bothers me that the Band would be more expensive, better built and more useful than the actual watch is. Also, If your eyesight is not the greatest or maybe you're older with slight vision problems, good luck trying to read the time or date at night with the tiny little window at the bottom, which is the only thing that lights up in the dark. That's right, the rest of the watch face is pitch Black except for that tiny window at the bottom.. Not easy to see with sleepy eyes, or in a dark car, or movie theater, etc.. Good luck! I will be returning for a refund. ... show more

    • Great buy for every day watch
Style: AQS820W-1AV Color: Black
It's easy to use the functions, light weight an accurate, easy to read I am 84. Had auto mechanical watches before, this is much lighter, more accurate on time & sets the month automatically for price that's 1/5 of my auto watches. Change the band if don't like it it & it still will be a great buy.

    • Great casio watch
Style: AQS820W-5AV Color: Beige
Great watch for casual wear. The sand color goes well with many outfits. Im glad I bought it, yet my wife didnt at first. She didn't like the sand color at first, but now likes it now that she see's it goes well with deferent shirts. On another note, this Casio has a similar functionality as a G Shock and I love the Tough Solar. Plus this watch seems to be more durable than my Timex that used to work. Caution: just don't go crazy with it because it has resin glass instead of mineral. Overall, great watch for the budget ... show more
