In an age of smartwatches is difficult for a manufacturer of classic watches to impress. Citizen has achieved this goal after presenting their latest wristwatch, Eco-Drive One, which is the thinnest watch in the world that can also charge when exposed to light.

Eco-Drive One will be available in a limited edition of 800 units and will cost around $6000. The watch casing has a thickness of only 2.98 mm and is made of Cermet, a ceramic-metal hybrid. The strap is made of crocodile skin. There will be a version with stainless steel housing which will cost  $2600. This version will also have the stainless steel bracelet.

The watch will be available in the autumn of this year. Citizen promises that Eco-Drive loading One will have an autonomy of 10 months from 1 single charge. The Eco-Drive technology can generate electricity from light from any source, natural or artificial.

Citizen has sold more than 30 million Eco-Drive watches since the launch of the system in 1976.
