Citizen Eco Drive Bluetooth Watch(1/1)

In 1976, Citizen released the world's first analog photovoltaic clock, a "timeless watch that does not require battery replacement". This is called Eco-Drive. Citizen's unique technology has made it possible to move the watch with a little light. The light passes through the dial and is converted to electricity in a solar cell, which is transmitted to the motor and runs the watch. The surplus electricity is stored in a secondary battery (rechargeable battery), so some models continue to operate for more than 6 months in the dark. "Eco Drive Bluetooth" works with your smartphone via Bluetooth connection. You can automatically adjust your watch to the time of your current location, and simply tap the world map in the app or enter a city name to set your watch to the time of 316 cities, including UTC (Coordinated Universal Time). With this function, you can set the exact time immediately. It also supports notifications from major SNS, and you can find the missing smartphone by operating the watch.
