radio-controlled watch “d”gƒEƒHƒbƒ`
情報・通信 / ハイテクノロジー

A wristwatch that automatically makes daily corrections to its displayed time via an ultra-sensitive miniature antenna that receives a radio signal from an atomic clock containing the correct time. Its time base will fluctuate by only 1 second every 10,000 years. If it cannot obtain a radio signal, it will automatically switch over to a built-in sensor that will make any necessary adjustments to the time. Found mainly on Earth. It is rarely used in space, where the constant bombardment of cosmic rays interferes with its reception.

This is the type of watch Jonathan Ingram received from Lorraine.
