Casio Men Solar-Powered Analog-Digital Watch - Green | AQ-S820W-3BVDF is a versatile solar watch inspired by the appearance of aircraft instrument panels. Its round flat bezel, contrasting white hands and indexes, and LCD positioned at 6 o'clock create a sporty, easy-to-read design for active everyday use.

The watch combines analog and digital timekeeping. The analog section uses two hands for hour and minute, while the digital display shows hour, minute, second, PM, month, day, and a six-language day-of-the-week indicator supporting English, Portuguese, Spanish, French, German, and Italian.

For international travel, the AQ-S820W-3BV provides World Time across 31 time zones, 48 cities plus UTC, with daylight-saving time adjustment and Home City/World Time City swapping.

Timing functions include a 1/100-second stopwatch with elapsed, lap, and split-time measurement. The watch also includes two countdown timers suitable for interval training, with auto-repeat configurable from 1 to 10 repetitions.

Additional features include five daily alarms, an hourly time signal, amber LED illumination with selectable duration and afterglow, a full auto-calendar through 2099, and selectable 12/24-hour time format. Button-operation tones can also be switched on or off.

The resin case measures 52.5 × 50.1 × 12.7mm and the watch weighs approximately 46g. It uses a resin band suitable for wrist sizes from approximately 145 to 215mm, while resin glass protects the display. Casio rates the watch for 100-meter / 10-bar water resistance.

Its rechargeable battery is powered by light through Casio's solar charging system. After a full charge, Casio specifies approximately 10 months of normal operation without further light exposure, or up to 23 months when stored in darkness with Power Saving enabled.
