Key Features

• Solar Powered Operation – Utilizing Casio’s Tough Solar system, the watch converts light from any source—sunlight, office lighting, or even low indoor lamps—into electrical energy. This self-sustaining power system ensures long-term reliability and reduces environmental impact by minimizing battery waste. A CR2032 battery is included for initial setup, but ongoing operation relies entirely on solar charging.
• 100 Meter Water Resistance – Rated for depths up to 100 meters, this watch is fully suitable for swimming, snorkeling, and other water-related activities. It’s built to withstand splashes, rain, and submersion, making it a trustworthy companion for aquatic adventures and daily wear in wet conditions.
• 1/100 Second Stopwatch – Offers precise timing with accuracy down to one-hundredth of a second. Ideal for tracking athletic performance, interval training, or any activity that requires split-second measurement, this feature ensures you can monitor your progress with confidence.
• LED Backlight – Equipped with a bright LED illumination system, the watch provides clear visibility in dark environments. Whether you’re checking the time during an early morning run or navigating a dimly lit room, the backlight ensures legibility without straining your eyes.
• Countdown Timer – Includes a practical countdown timer function that helps manage time-bound tasks such as workouts, cooking, or study sessions. Set it for precise intervals and stay on track with audible alerts when time elapses.
• Multi-Alarm System – Features multiple alarms—up to five—allowing users to set reminders for daily routines, medication schedules, or wake-up calls. This flexibility makes it especially useful for professionals, students, or anyone managing a busy timetable.

Important Notes

This model is not discontinued and remains available for purchase. The included CR2032 battery supports initial operation, but long-term functionality depends on regular exposure to light for solar charging. While the watch is suitable for swimming and snorkeling, it is not designed for scuba diving or high-impact water sports. To maintain water resistance and overall performance, follow Casio’s care guidelines—avoid pressing buttons underwater and clean the watch after exposure to saltwater or chlorine. With proper maintenance, the AQS800W offers years of dependable service.
