Strap on this designer wrist watch, that is entirely powered by water … or more precisely, entirely powered by water in its function as an electrolyte between the copper and magnesium, that is mounted inside the watchs tiny water tank.
When in contact with water, the magnesium and copper will release + ions in a chemical reaction that can be converted into electric energy to power the watch and its display.
Your water powered wrist watch will hold its power for up to 5 days pr. dose of water. And when the display starts to fade, all you have to do is to empty the water tank and refill it with fresh water. After each refill the watch will need a few seconds to restart again.
- 6 digit time display (hours, minut, seconds)
The Water Powered Wrist Watch is available for 329 DKK ($58 USD) from Gadgets.dk.
