Each Eco-Drive watch features a stainless steel case and a scratch-resistant crystal. With the invention of the Eco-Drive calibre 7878, Citizen was able to start manufacturing watches with more innovative and cutting-edge designs, including the Eco-Drive Slim introduced in 1996.Įventually, the movements evolved to include a broad range of design features, including complex analogue and digital-analogue movements, as well as complications such as the chronograph.ĭespite Citizen’s competitive prices, the brand always uses top-notch materials in its watches. Before the Eco-Drive calibre 7878, Citizen was producing solar watches with solar cells mounted directly on the dial, making the watches look bulky. This innovation was made possible because of the introduction of a much-thinner film amorphous silicon or the absorbing film layer for solar cells.
A solar cell refers to an electrical device that converts light energy into electricity. Making the Eco-Drive concept possible was the Eco-Drive calibre 7878 movement, the first light-powered movement wherein solar cells can be mounted under the dial, and not above it. The Workings of a Citizen Eco-Drive Movement Just imagine the great help it gave to the environment when people started using light-powered watches that don’t need battery replacements. And in 1976, the now-iconic Eco-Drive technology was introduced, to the delight of the environmentalists.
The brand started experimenting with solar-powered movements. More than 100 years later, Citizen continues to produce cutting-edge and innovative lines of watches that enchant watch connoisseurs the world over.Ĭitizen didn’t stop at mastering the quartz movement in the 1970s. This time, it was more aggressive and innovation-driven, with the sights of expanding overseas. When the war ended, however, Citizen was back in business. The eruption of World War II brought a stop to the company’s watch production. In 1924, they sold their first commercial pocket watch under the label Citizen.
In 1918, Japanese jeweller Kamekichi Yakamazi founded the Shokosha Watch Research Institute and started producing pocket watches.

If you’re a watch-loving environmentalist, then you would agree that the creation of the Citizen Eco-Drive technology is one of the best things that ever happened to the watchmaking industry.Ĭreated in 1976 by Citizen, a Japanese electronics company well known for their solar watches, the Eco-Drive is the world’s first light-powered quartz mechanism.
