Frequently Asked
Questions About the AQ-S820W Solar
No. It is solar powered, charging from any light source, so the twin analog-digital displays run without a cell swap.
It carries both physical hands and a digital display on the same dial — analog time at a glance with digital functions underneath. It is one of the cheapest ways into a solar ana-digi watch.
They are siblings in Casio's AQ-S800 solar ana-digi family. The AQ-S810W carries a stated 100m water resistance rating and a six-language day-of-week display; for the AQ-S820W's exact rating and functions, check the current Amazon listing rather than assuming they match.

Inventors of the G-Shock — the most indestructible watch ever made.
Casio engineer Kikuo Ibe spent two years and broke over 200 prototypes to develop the original G-Shock in 1983, designed to survive a 10-meter drop. Forty years later G-Shock is worn by Navy SEALs, mountaineers, and luxury watch collectors alike. The CasiOak (GA-2100 series) reinterprets that DNA in Royal Oak proportions.
