A must by for any Casio watch collector
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.

Great everyday watch – tough, solar-powered, and super practical
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.

Great casio watch
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

Incredible value
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.

Good Watch for the Price
This watch is really nice and a good value. It is a better-looking watch than the previous one in the series. Once you figure out how to set it, it works great. I am very happy with it.

Good value
I like Casio watches in general and this is no exception. It’s a great everyday watch that recharges from sunlight.

Great value solar watch.
Typical Casio quality. Arrived in good condition. Very easy to set up and align hands if you’re familiar with G-shock watches. Size is good, it’s big but not too big. Analog and digital displays are easy to read. I like it much better than the 810 model. Would purchase again. Update: I added a 34mm hardened glass screen protector to the scratch prone acrylic crystal so no more worries about scratching it. Second pic is with screen protector installed. Perfect fit. Great watch so far. Love it!

Good idea?
Pros Solar power and you do not worry a battery Cons Programming this watch is difficult! World access means you have to have this right before you can do anything else. Getting the time right is also hard because the hands move at the touch of a button and they move quickly. Instruction manual definitely could be better.

I am becoming obsessed with watches my brietling was my only watch which was ok but I would never wears it when gardening etc. so I started researching other brands that were capable of taking a hiding.i now have25 watches all Casio and citizen. And one or two seikos . I had to get this little belter from the US as I could not get anything but black in the uk . It’s a fantastic good looking watch I fell I love as soon as I saw it. I will have to get the other two colours without she who must be obeyed finding out. It functions flawlessly it’s light to wear and it has real wrist presence. Friends have asked to see it and are considering getting one. Buy it you wont regret it.

Satisfecho con la compra, buena calidad y bonito, su desventaja es que de noche no ilumina mucho la luz y las manecillas no brillan suficiente
