CITIZEN pioneered the technological breakthrough which was the development of a light-driven watch. This engineering innovation well ahead of other watch manufacturers as early as 1976, which led to the launch of the highly acclaimed Eco-Drive in 1995. Utilizing electrical power converted from virtually any light source, this extraordinary innovation changed forever the way watches could be powered. Eco-Drive eliminated the need to ever replace batteries, which made it especially beneficial to areas where such specialist batteries were not obtainable. This leveled the field for citizens of virtually every country to be able to experience unrestricted joy of wearing and using a CITIZEN watch.
