Article Summary
October 12, 2007 Citizen has displayed an innovative earthquake warning concept watch at CEATEC Japan 2007. Jointly developed with Rhythm Watch, the device combines an Earthquake Early Warning (EEW) receiver and an analog watch. The Seismic watch functions as an ordinary watch until it receives the EEW, which causes the hour hand to speed up based on the seismic intensity estimation, while the minute and second hands give the countdown time to the earthquake arrival.
