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.

Works great but the you can't see the hands in the dark.
Great deal on a set it and forget it solar watch. The only complaint is that you can't see the hands in the dark. It does have a digital display that lights up, but too small for my older eyes.

Simple solar watch. Good Value.
Less than $60 for a Solar Watch. You'll never need a battery replacement. But who needs a watch these days when everyone has a phone? Our children will, when we start to keep mobile phones out of the classroom. This is a clean, no fuss, simple function time piece. The only drawback is that this is analog. Who teaches how to tell time on an analog clock? You can.

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.

A Real Pleaser
This is a big watch with a case diameter of 48.5mm. The case and strap is resin, and the back is stainless steel. I am pleased with how light it is. The resin watch strap is very long, but fits a 6-inch wrist all the way to maybe an 8 inch wrist. I was able to cut off 3/4 of an inch from the tip of the strap. Actual lug width is 18mm, even though the watch band is 24mm wide. For being such a big watch, it is surprisingly light. The resin wrist strap is also light in weight, and very comfortable, so I won't need to replace it at all. This watch also has a digital display at the 6 o'clock position that you can scroll through to tell you the time, world time, date, alarms, stopwatch and timer. There is a light for the digital display that you can adjust from 1 second to 3 seconds. The analog dial is not illuminated, but has lume on the hands and indices. There is no second hand. When you set the time on the digital display, the analog hands will move to the correct hour and minute. Pretty neat. I had my doubts, but ended up liking this watch a lot.

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

Two Irritations
A good value for the money Tough Solar watch. The band is one star: stiff, to long and unconformable to wear. When you buy this watch and agree with me, consider purchasing the 18mm to 22mm band adapter. I choose Zichao but have not received them yet. By pressing the lower right button a number of times, the LCD shows month-date-seconds then time with seconds then day of the week with seconds. What is preferred is month-date-day of week. I do not need seconds on each display. UPDATE: Zichao 18mm to 22mm adapter does not work. The 18mm tang is not lone enough.

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.
