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.
