(Headquarters: Nishi-Tokyo City, Tokyo / President: Yoshitaka Oji, hereinafter "Citizen") will hold an "Eco-Drive" 50th Anniversary Event at Omotesando Hills Space O in Omotesando, Tokyo, on June 13 (Sat) and June 14 (Sun), 2026. Citizen is celebrating its 50th anniversary this year since launching the world's first analog light-powered wristwatch (now known as Eco-Drive) in 1976. Citizen's unique "Eco-Drive" technology, which converts even faint indoor light into electricity to power the watch, not just sunlight, has pioneered the future and possibilities of watches and is currently deployed in over 140 countries and regions worldwide. To mark this special milestone, we will hold the Eco-Drive 50th Anniversary Event with the aim of allowing a wide audience to experience the 50 years of evolution and charm that Eco-Drive has journeyed through. At this event, you can experience the evolution of design and technology through various contents, while unraveling the development background and history of "Eco-Drive." We plan to exhibit archives that are not usually seen, including the Eco-Drive 50th Anniversary Limited Edition model "Eco-Drive PHOTON," scheduled for release this autumn. Please come and experience the charm of "Eco-Drive" at the venue.
