Radio Controlled Solar

The long-wave transmitter in Mainflingen, Germany, continuously sends time signals generated by the caesium atomic clock in Braunschweig. Since atomic clocks have a precision tolerance of one second in a million years, radio-controlled watches are as close as you can come to absolute timekeeping. This functionality requires that the timepiece is within 1,500 km or just over 930 miles from the transmitter. Even so, quartz watches, despite all their precision, have one serious disadvantage – limited battery life; however, alternative energy sources for environmentally sound quartz timepieces have long since entered the sphere of the ordinary. Innovative solar technology in solar radio-controlled watches contributes to environmental preservation by eliminating the need for battery changes, but still allows precise time measurement.
