EARLIER SATELLITE WAVES Citizen’s first Eco-Drive Satellite Wave, the world’s first light-powered satellite-synchronized analog watch, released in 2011, and could acquire a time signal in a minimum time of six seconds. Three years later, in 2014, the Citizen Eco-Drive Satellite Wave 100 could reach its signal in half the time, in as little as three seconds. By providing each of the three hands—the hour hand, minute hand and second hand—with its own independent motor, adjusting the time became totally stress-free. That model was also the thinnest satellite-synchronized watch in the world. In 2015 Citizen developed a model that could capture not just time signals, but positional data as well. That watch, the Satellite Wave F900 and the chronograph version, called Citizen Satellite Wave World Time GPS, are multifunctional light-powered GPS satellite-synchronized watches designed to maximize GPS functionality. Both feature a motor that can drive the hands both clockwise and counter-clockwise extremely fast.
