The Casio AQ-S820W-3BVEF from the Classic Collection series is a men's multifunction sports watch, generally popular for its great value for money and durability. Its design and practical workmanship make it suitable for everyday wear and sports.
The Casio AQ S820W-3BV offers essential functions that you can use in your daily routine and leisure activities. The watch's combination dial stands out for its great clarity, displaying classic data such as date, day of the week, stopwatch. The watch calendar is fully automatic. The watch does not lack world time, alarm, or countdown. For trouble-free readability in darkness and low-light conditions, the watch is equipped with LED display illumination. A great advantage of the model is the solar power supply, ensuring long running. The watch's battery, powered by natural and artificial light, has a lifespan of around 7 to 10 years and is then replaced in exactly the same way as a conventional battery.
The resin case of the watch is complemented by a green resin strap. Thanks to the clear dial and the practically designed control with 4 buttons, the watch will soon become a natural part of you. The dial is protected by a plastic glass. The case diameter of 50 mm makes the watch a large watch. The water resistance of this model is 100 m, so there is no need to put it away when showering or swimming.

Casio, Japan is one of the best-selling watch brands in the world. The first watches from the Casia workshop were digital and at the same time the first in the world to display the date. Casio's digital watches are no longer popular today, although analog watches or watches with a combined time display already form a large part of the range.
Casio has made history with its range of super-durable G-Shock watches, which are equipped with a light but sufficiently durable construction (against falls of up to 10 m, shocks, vibrations, magnetic field and temperature fluctuations) and a great value for money. The glory of the G-Shock watch over time also required a lightweight women's version - Baby-G. The Casio Pro Trek or Casio Edifice outdoor watches are also very popular. Casio does not lag behind in modern technology either, as evidenced by models equipped with Bluetooth technology, the Tough Solar solar drive or the high-precision radio-controlled Wave Ceptor watch.
