Citizen Watch Co., Ltd. (Headquarters: Nishi-Tokyo City, Tokyo / President: Yoshitaka Oji, hereinafter Citizen) will hold the 'Eco-Drive' 50th Anniversary Event on Saturday, June 13th and Sunday, June 14th at Space O, Omotesando Hills in Omotesando, Tokyo. Citizen celebrates its 50th anniversary this year since launching the world's first analog light-powered wristwatch (currently Eco-Drive) in 1976. Citizen's unique Eco-Drive technology, which converts even faint indoor light, not just sunlight, into electricity to power watches, has pioneered the future and possibilities of timepieces and is currently deployed in over 140 countries and regions worldwide. To commemorate this special milestone, the Eco-Drive 50th Anniversary Event will be held with the aim of broadly sharing the 50 years of evolution and appeal that Eco-Drive has achieved. At this event, you can experience the journey of design and technology through various contents, while exploring the development background and history of 'Eco-Drive'. In addition to the Eco-Drive 50th Anniversary limited edition model 'Eco-Drive PHOTON' scheduled for release this autumn, there will also be an exhibition of archival items not usually seen.
