The alarm clock is powered by water. As long as it fills with water, the watch will be active. It is designed to take advantage of the chemical reaction between water and internal metal to provide electricity. Instead of using batteries, which means it is totally environmentally friendly and energy-conserving.
The watch uses the electrolyte in the water to generate electricity. This process will produce some impurities that are completely non-toxic and free of heavy metals. Therefore, it is 100% environmentally friendly and does not cause pollution or harm to human health.
The clock provides functions of time, daily alarm, and so on. It can be changed from 12/24 hours or ° C / ° F Temperature. It is very simple and easy to set up even the elderly and children can use it. Ideal for home, office, school, etc.
We recommend that you use tap water, as it contains more electrolytes. Due to energy efficiency, the alarm sound is not too loud, and there is no backlight. Fill the water once provide feeding for about 3 weeks, please change the water regularly.
