Solar battery. I've had a Casio solar watch for 10 years now with no problems. And surfing, and in the sea and in the mud and diving. Therefore, instead of G Shock, I chose the usual ones - solar-powered with large numbers. Ebb and flow tides are not needed, world time has come in handy more than once. The backlight is good. Bracelet no problem. As a spare watch for two or three days a week and for rest, that's it. Hours do not regret, for a year no problems. Charging almost always shows a full battery. Even in Hong Kong in winter. The price is adequate.
