1990 Radio Controlled
In 1990, Junghans offered the first radio-controlled wristwatch, the MEGA 1. In this type, the watch's quartz oscillator is set to the correct time daily by coded radio time signals broadcast by government-operated time stations such as WWVH, received by a radio receiver in the watch. This allows the watch to have the same long-term accuracy as the atomic clocks which control the time signals. Recent models are capable of receiving synchronization signals from various time stations worldwide.
