This water powered clock Alarm requires no batteries and no electricity!!!! Just add a small amount of tap water to the replaceable water battery to make it work.
If that wasn't enough, this clock also has 4 different functions (it Displays Time, the Temperature, Set Alarm, and Timer) that can be accessed by turning the clock 1/4 turn to the right or left.
Dimensions: 9.5 x 9.5 cm
The battery life is about é-3 years. You can then buy a new battery (please contact us)
