Casio WVA-M650D-2AER Radio Solar 44mm 10ATM

To activate the watch's backlight, simply give your wrist a slight twist. This works as soon as the ambient light decreases. Independent and eco-friendly, solar cells provide the watch with power. Excess solar energy is stored in a battery. Whether in Europe, North America, and Japan, or in large parts of Canada, Central America, and China - once the watch is set to the local time zone, it receives the corresponding radio signal and always displays the exact time. In many countries, it also automatically adjusts for daylight saving time and standard time.
