Citizen introduced the Eco-Drive Satellite Wave in 2011, the first timepiece powered by GPS satellites to accurately display the time anywhere in the world. This year during Baselworld 2015, they have announced that they’re following up with the introduction of Eco-Drive Satellite Wave F900.
This year’s model features a dual-time display function, which allows the watch to display the time in two different time zones simultaneously.
It features a high-speed twin-coil motor, designed specifically for the Eco-Drive Satellite Wave F900, allowing the hands to spin fast in both normal and reverse rotations, to quickly and smoothly correct the time between zones. Signal receptions are received within 30 seconds and under the right circumstances in as little as 3 seconds.
The 45 mm case and watch band are made from SuperTitanium, ensuring its protection against scratches. Housed within the case is an in-house F900 caliber movement.
The Eco-Drive watch is powered entirely by light as the power source. It is able to generate power from any light source – even dim light – to keep the watch running without the need for replacement batteries. A light-level indicator on the display shows the amount of electricity generated by light absorbed by the dial.
Two different versions are available – one in black and the other in white, which are limited to 1,700 and 1,300 timepieces exclusively.
