The Casio AQS820W Solar Powered Watch is a truly remarkable timepiece. It stands out in the market. In the video above, Greg Anderson shares his personal insights. He highlights why this particular Casio model is a standout choice. This watch offers exceptional value. It features robust solar technology. This article expands on its capabilities. It details why the AQS820W could be your next essential watch.
Embracing Casio Tough Solar Technology
The Casio AQS820W Solar Powered Watch integrates Casio’s renowned Tough Solar technology. This feature eliminates the need for frequent battery changes. Small solar cells on the watch face capture light. They convert it into electrical energy. This energy then charges an internal rechargeable battery. This system works with various light sources. It charges effectively under sunlight or even indoor lighting. This provides a truly maintenance-free power solution.
First, consider the environmental benefit. You are reducing waste from disposable batteries. Second, appreciate the convenience. There is no more worrying about a dead watch battery. Many users keep their Casio Tough Solar watches for years. Greg mentions his oldest Tough Solar watch. It has been running for 19 years. He has never opened it for service. This demonstrates impressive longevity. It shows the reliability of Casio’s solar engineering. This feature alone makes the Casio AQS820W an attractive option.
Understanding Time Synchronization: A Comparison
The Casio AQS820W Solar Powered Watch is a strong contender. It achieves this despite lacking automatic time-setting features. Other premium Casio watches offer Multi-Band 6 or Wave Ceptor technology. These receive radio signals from atomic clocks. These broadcasts ensure extreme accuracy. In North America, the WWVB signal from Fort Collins, Colorado, is used. Other Casio models also feature Bluetooth connectivity. This allows them to sync with a smartphone app. This provides accurate time globally, especially where radio signals are weak.
First, the AQS820W foregoes these auto-setting features. This choice helps keep its price remarkably low. Second, setting the time manually is still straightforward. The process is simple and intuitive. You will not need to adjust it frequently. A quick seasonal adjustment for Daylight Saving Time is easy. For many users, this trade-off is perfectly acceptable. It offers a significant cost saving. You get excellent solar power without the premium for atomic or Bluetooth sync. This makes the Casio AQS820W a smart budget choice.
Core Functions of the Casio AQS820W
The Casio AQS820W features a blend of analog and digital displays. This offers clear readability. The analog hands show hours and minutes. The LCD window displays seconds. This also shows the day of the week. You can toggle the LCD display easily. It can show the full date. It can also show the complete time with hours, minutes, and seconds. You can choose between 12-hour or 24-hour formats. This flexibility caters to different preferences.
First, battery status is critical for a solar watch. This model displays its charge level. It shows “High,” “Medium,” or “Low.” Greg advises keeping the watch exposed to light. This ensures optimal charge. Storing it in a drawer for weeks may drain the battery. Wearing long sleeves that cover the face can also reduce charge. Normal daily wear, however, usually keeps it at a “High” charge. Second, a special rechargeable battery is used. This can be replaced if needed after many years. However, its impressive longevity often negates this concern.
1. World Time at Your Fingertips
The Casio AQS820W includes a practical World Time mode. This allows tracking of 48 cities across 31 time zones. You can easily select different time zones. Use the search button to scroll eastward.

The AQS820W features a distinctive two-stage countdown timer. This is highly customizable. You can set two separate countdown durations. Timer one has a maximum of 99 minutes and 55 seconds. Adjustments are made in five-second increments. Timer two also allows for custom settings. Once the first timer concludes, it beeps briefly. Then, the second timer automatically begins. This is ideal for interval training. It’s also great for cooking. You might need to manage sequential tasks. This timer can also repeat. You can set it to cycle up to 10 times. For instance, two 5-minute timers repeating 10 times total 100 minutes. This advanced functionality is a significant benefit. It adds versatility for various timing needs.
4. Reliable Stopwatch Function
The integrated stopwatch offers precise timing. It measures up to one hour. The display shows minutes, seconds, and hundredths of a second. It includes standard start, stop, and reset functions. There is also a split-time feature. This allows for tracking lap times. If left running, it automatically resets to zero. Then it continues counting. This function is perfect for sports. It’s also useful for other timing activities. Its accuracy and ease of use make it a valuable tool.
Setting Up and Maintaining Your Casio AQS820W
Setting up your Casio AQS820W is straightforward. First, you select your home time zone. The search button moves eastward through zones. The light button moves westward. Next, you can enable or disable Daylight Saving Time (DST). This is an easy toggle. You then choose between 12-hour or 24-hour display formats. The watch allows for resetting seconds, hours, and minutes. It also lets you set the year, month, and date. The calendar is pre-programmed through 2029.

Choices include English, Portuguese, Spanish, French, German, and Italian. These settings personalize your watch experience. They are typically set once. You rarely need to adjust them again.
Hand Alignment and Troubleshooting
Occasionally, analog watch hands might misalign. This can happen due to shock or magnets. The Casio AQS820W has a simple solution. The digital time always serves as the reference. If hands are off, you can easily realign them. Press and hold the adjust button. Keep holding until “H.SET” appears. The hands will then move to the 12 o’clock position. You can then make fine adjustments. The minute hand moves in 1/3 minute increments. This ensures perfect synchronization with the digital display. This user-friendly feature means you rarely need professional service. It maintains the watch’s accuracy effectively.

It’s not as rugged as a G-Shock’s 200-meter rating. However, it still handles everyday adventures well. The watch features a slightly raised bezel. This protects the crystal from common scratches. The crystal material is soft resin. Minor scratches can often be buffed out using Polywatch. This keeps your watch looking new. It adds to its practical longevity. The overall construction feels solid for its price point.
This watch weighs a mere 45 grams. It feels lightweight and comfortable on the wrist. A standard G-Shock Square, for comparison, weighs around 51 grams. The design provides high contrast.
