You’ve heard of solar watches before, but wait until you see what the Casio G-Shock GWG-1000-1A3ER has to offer. A sophisticated solar charging system, breathtaking autonomy: welcome to the future of watchmaking.

A dial that does much more than tell the time

The first thing that strikes you about the Casio G-Shock is that embossed black background of the dial. But make no mistake, this isn’t just an aesthetic choice. This innovative design actually conceals tiny solar cells. These cells, like spies from the future, are in ambush, watching for each ray of sunlight to transform it into precious energy.

The incredible promise of autonomy

Even if it remains hidden in a drawer, deprived of sunlight, this watch continues to run for almost half a year. A technological feat that makes the competition green with envy.

An ingenious warning signal

But what happens if, unfortunately, the battery runs out? Do not panic ! The Casio G-Shock has thought of everything. If the second hand starts to jump every two seconds, that’s the signal. It’s her way of saying, “Hey, it’s time to give me some sunshine!”

  • Sophisticated design : An embossed black background which hides ultra-efficient solar cells.
  • Phenomenal autonomy : Up to 5 months without seeing the sun. Who says better ?
