Setting the time on the display is tedious because it is far too small. Once you finally manage it, the time is readable with the hands. The display is simply too small.

Very light and robust, my choice for swimming in the sea. Bluetooth and the Casio app are a nice addition. Thanks to the solar function, you won’t be surprised by a dying battery while on holiday.

The watch is very nice and the strap is light, but I will never manage the settings and therefore I am returning it

Kaufland.de Kunde

You know the drill from Japanese products, and this is no exception: absolute top quality, as you’d expect from brands like Casio, G‑Shock and other watch makers from the Land of the Rising Sun. I’m thrilled with my first G‑Shock.
