I’ve seen water powered clocks and calculators but never a Water Powered Wrist Watch before. Just drop in some H20 and the thing will stay powered up for some 5 days. Complete with calednar and stopwatch. Around $58.00 in Danish stuff.
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.
