The optical kinetic energy radio wave meter receives the　standard time　radio wave sent by the transmission tower through the radio wave receiver and antenna built in the watch, obtains the time, calendar and other data, and automatically corrects the time and date of the watch. The standard time signal adopts the theory of high-precision cesium atomic watch, with an error of one second in 100000 years. The radio wave watches of xi'tiecheng are all powered by the light kinetic energy technology, using any visible light source as the energy source. As long as there is light, there is energy, and as long as the radio wave can be received, there will never be error.
