Review: The AQS810W (5208 module) series is one of Casio's best, in terms of being durable, reliable and problem-free. - This is my second AQS810W... my first is about five years old, and it's black with white lettering. The "Tough Solar" and "Illuminator" are long-gone, rinsed away by automotive degreasers and other auto repair chemicals, but I like it better without those pronouncements, anyway. Army Green, in my opinion, is an excellent color on this watch. The fact that this is not at all a glossy watch, but a matte (or semi-gloss?) finish makes the color attractively subtle. I like it even more than the black. Other than the color, though, it's the exact same watch I've been very happy with for the last five years. Easy to setup, rugged and sturdy, just the right size (for me) and an industrial, utilitarian look. This is a very comfortable watch to wear - light in weight, flexible band, no sharp edges or uncomfortable shapes. I spent a few weeks trying to decide what watch I was going to get, and I came to the conclusion that being solar-powered was my highest priority, followed by being quickly readable. Perhaps it is just me, but I can read a analog watch faster than a digital one - just a quick glance. I kept coming back the Casio's AQS810W series, and it came down to the darker, matte-finished colors. Having said all of that, this series of Casio watches is virtually trouble-free. Read the reviews! VERY FEW failures, defects, water intrusions. People who don't like this series of watches either find them incomprehensible to set or are unhappy with the small digital display or the lack of a backlight for the analog dial. The watches themselves are largely bulletproof, possessing anvil-like reliability and durability. They even have a feature that if the watch is dropped or knocked around too hard, and the analog hands get out of sync with the digital display, you can quickly and easily re-sync them. This series is one of Casio's best, in terms of being problem-free. Yes, they have acrylic crystals, not mineral glass, and they do scratch. Simply buff the scratches out, and it is as good as new. Worried about the band breaking or falling apart? On a regular basis, take the watch into the shower and scrub the whole thing with an old toothbrush and some shampoo. Not only will it be clean and look great, but removing the body oils, sweat and salts makes the bands last and last. That's the secret to getting Casio resin bands to live long lives. The analog dial is not lit, but neither is the dial on my Rolex or Omega. Just find a light source to reflect on the hands, and you're in business. Just like we've done for many years. Anyway, you can tell I am a fan. Buy with confidence, but download the pdf version of the Casio 5208 module operating instructions, and it'll be easier to set up the watch if you aren't very tech savvy. If you like the way this series of watches looks, then I'm pretty confident you'll be very happy with your purchase. Have fun!
Review: Tough, Durable, Water Resistant Watch Suitable for Outdoor Use - I normally don't write many reviews; however, this watch is an exception. First, it is a $40 watch. On that premise, it will not have the Carbon Core associated with a GShock watch or an atomic clock function. It does do the following REALLY well: 1) You set the clock once, and it keeps that exact time. 2) It is very water resistant. I spent a full 6 days, 12 hours a day, at Summer Camp getting BSA lifeguard certified. I never took off the watch. I swam 3 miles, dove 12 to 13 feet down retrieve dozens of 10 lbs anchors, and swam out to retrieved three exhausted swimmers. This watch didn't miss a beat. 3) The crystal can take a beating without scratching. The watch hit several canoe gunnels, face first and I can't find a scratch 4) it is very light weight and quite comfortable. I forgot I was wearing watch, even when doing water rescue exercises and people grabbing my wrists and the watch. 5) The analog watch hands are big and easy to read. The digital display does take a few hours, for me, to fully understand how to program and get used to it. However, I can now easily cycle through day, date, and digital time. I believe that Casio keeps the digital seconds displayed because the analog hands lack a second hand. That may take some getting used to, but I learned to appreciate it. In the end, this $40 watch does everything I need. I was looking for a durable watch with analog hands I could use for Boy Scouts, and the green model fit the bill. If you travel, which I don't, you have the World Time feature, but you must determine for yourself what features to prioritize. For me it was: 1) Durable 2) Long life, Tough Solar for the win 3) Easy to read analog hands 4) very water resistant. I am not a diver, and 15 feet depth is the most I would expect to dive.

## Features

- TOUGH SOLAR POWERED FOR LONG-LASTING PERFORMANCE The Casio AQ-S810W-3AV uses Tough Solar technology to convert light into power, eliminating the need for routine battery replacement. After a full charge, the rechargeable battery provides approximately 10 months of operation without further light exposure, or approximately 23 months when stored in darkness with Power Saving enabled. A battery power indicator and Power Saving function help manage energy.
- SPORTY FOREST GREEN DESIGN WITH A LIGHTWEIGHT PROFILE Measuring 52.2 × 48.3 × 13.7 mm (L × W × H) and weighing just 40 grams, the watch features a resin case, resin bezel, resin glass, and resin band for a lightweight design suited to active everyday wear. The forest green colorway adds a distinctive outdoor-inspired look, while Neobrite on the hands helps improve visibility in low-light conditions.
- WORLD TIME FOR 48 CITIES ACROSS 31 TIME ZONES Designed for travel and international use, World Time covers 31 time zones and 48 cities plus Coordinated Universal Time (UTC). Daylight saving time can be switched on or off, and the Home City and World Time City can be swapped for added convenience.
- TWO INTERVAL TIMERS & 1/100-SECOND STOPWATCH FOR TRAINING Two independent countdown timers can be used for interval training that alternates between two different paces. Each timer measures in 1-second increments, supports settings from 5 seconds to 99 minutes 55 seconds, and allows 1–10 repeat cycles. The 1/100-second stopwatch measures elapsed, lap, and split times up to 59 minutes, 59.99 seconds.
- 100M WATER RESISTANCE, 5 ALARMS & AMBER LED LIGHT Built for active use, the watch provides 100-meter water resistance and includes 5 daily alarms, an hourly time signal, and an amber LED light for the LCD portion with selectable 1.5- or 3-second illumination and afterglow. Additional features include a full auto-calendar through 2099, 12/24-hour format, 6-language day-of-week display, button-tone on/off, and approximately ±30 seconds per month accuracy.

## Questions & Answers

**Q: Does this watch has atomic time keeping?  Thanks in advance.**
A: No, it does not have atomic time keeping but it keeps great time. I bought it because it's a reasonably priced solar time keeper. Its a great watch though...

**Q: Is the watch band canvas or is it resin (which life expectancy is a year)?**
A: Resin bands will last for years if they are washed periodically (it explains that in the user guide). I had these bands break years ago until I started washing with mild soap and water, especially after sweating.

**Q: Do these have the 12/24 hour format?**
A: Yes. You can change it in the settings. Has world time, alarms, stop watch, light, chrono...

**Q: Watch did not come with instruction manual. Where  can I find? Noticed some customers received a manual with purchase.**
A: I’d say that you have 2 options. Return the one you received without a manual and then order it again or check the Casio website for a link to the manual online. Good luck!

### ⭐⭐⭐⭐⭐ This is a Great Watch!
*by J***R on April 11, 2014*

Awesome watch!! I bought this watch three weeks ago, and I couldn't be more pleased. I needed a watch with a rubber strap. I work with natural stone, and the majority of the tools we use are water tools. I have never owned a watch with a rubber bracelet before this one, and I am very impressed with how comfortable and easy to keep clean it is. I also enjoy the green, orange and black color scheme. This watch has held up great! I shower with, swim, and work in this watch. I am very rough on this thing, and so far it has handled everything well. The solar feature works great! I received it with a full charge, and after the first day it dropped to medium. I placed it in a window seal for a few hours, and it has held a full charge ever since. I enjoy how lightweight and comfortable this watch is as well. It fits well on my medium sized wrist, it is not too big and bulky, but it is not a small watch either. The large numbers on the dial glow, and the digital screen has an illumination light. The digital display is kind of small, but the analog is very easy to read. The Arabic numerals are very large making them easy to read. This watch has all the great features you would want from a digital watch, with the style of an analog watch. All of the digital features are easy to use. I have always worn, and preferred an analog watch, so the : stopwatch, dual timers, and alarms have all been nice to have. The watch comes with a manual, but it is kind of small and hard to read. I would recommend going to Casio's web page where you can view, save, and print a much larger and easier to read version of the manual. The manual is easy to understand, and the watch is easy to program. This is my first Casio, and I could not be more pleased! I'm now thinking about investing in a G-Shock. The digital features on this watch have made me want one with a larger digital display, so I am wanting to buy a digital only watch. The GW6900-1 looks cool and is atomic and solar! It is also a good buy at around $79.00 on amazon right now. Check it out too, if you think you want a full screen digital instead, and don't mind spending a little extra cash.
