The Casio AQ-S820W-1AVEF is a versatile analogue-digital watch that blends classic Casio design with modern utility and solar-powered reliability. Inspired by aircraft instrument panels, its clear black dial features bold white indexes and hands for instant legibility, complemented by a compact LCD at 6 o’clock displaying day, date and secondary time functions. Durable yet lightweight, the AQ-S820W-1AVEF is ideal for everyday wear, travel and active routines, reflecting Casio’s focus on practical performance in a refined design.
Solar Power and Reliable Timekeeping
Equipped with Casio’s Tough Solar system, the watch harnesses both natural and artificial light to maintain power, eliminating the need for frequent battery changes. A battery power indicator and power-saving function extend operational life, with approximately 10 months of normal use and up to 23 months in power-save mode when stored in darkness after a full charge. Regular timekeeping is supported by an analogue two-hand display and digital hour, minute, second, month and day readouts.
Durability and Practical Features
The resin case and bezel (approximately 52.5 × 50.1 × 12.7mm) house a resilient construction that resists everyday wear, while water resistance to 100 metres (10 bar) permits swimming and surface water activities without concern. An amber LED backlight with selectable duration and afterglow enhances visibility in low light.
World Time and Everyday Utility
World time covers 31 time zones (48 cities + UTC) with daylight saving on/off and simple home/world city swapping, making this model a reliable companion for travellers. A 1/100-second stopwatch, dual countdown timers with auto-repeat for interval training, five daily alarms plus hourly signal, and a full auto-calendar through 2099 add everyday practicality. Additional functions include 12/24-hour format, mute button tone, six-language weekday display and accurate performance to 30 seconds per month.
