An Eco-Drive watch is a type of timepiece manufactured and marketed by Citizen Watch Co., Ltd., which is primarily powered by light. The technology behind Eco-Drive allows the watch to convert any kind of light, including natural and artificial light, into energy to power the watch and store the surplus energy on a power cell. This means that on a full charge, an Eco-Drive watch can run for months, even in darkness, without the need for regular battery replacement. The technology was first created in 1976, and it has been recognized for its contribution to environmental sustainability, receiving Eco Mark certification and a Gold Prize at the JEAs Eco Mark Awards.
In summary, an Eco-Drive watch is a sustainable and environmentally friendly timepiece that harnesses the power of light to function without the need for regular battery replacements.
