Gps digital clock

Styrax wireless synchronized master clock system operates on a very basic concept. The Master clock acquires the time and then transmits it wirelessly to the slave clocks that are in the system. Once the transmitter master clock receives a time update, it then transmits the time to any number of secondary slave digital clocks. The digital clocks need only a 240v ac power outlet; they include their own internal battery pack with 5 year life.
