With a bold design that takes its inspiration from the iconic 1973 original, the new Limited Edition Eco-Drive 365 encapsulates the 50-year journey from quartz to Eco-Drive in Citizen watches. Featuring a polished silver-tone case that measures 42.5mm across, the vintage-inspired design utilizes Citizen’s cutting-edge stainless steel processing and polishing know-how. An anti-reflective sapphire crystal protects the display, with the dial’s surface inspired by an endless starry sky and the innate beauty of the Earth. Lab-grown rubies and gold-tone accents harken to the vintage source material, while a pair of sharp, dauphine-style hands indicate the time. The supple brown leather strap provides added luxury and is certified by the Leather Working Group (LWG), emphasizing our sustainable partnership and commitment to environmental responsibility. Inside, the new light-powered, innovative Eco-Drive movement Caliber E365 is at work with an accuracy of ±15 seconds per month, and with the movement requiring exposure to adequate light to then run for 365 days on a full charge, without ever needing a battery.

CITIZEN Eco-Drive BN1010-05E History
History of Citizen
The company was founded in 1930 by Japanese and Swiss investors. It took over Shokosha Watch Research Institute (founded in 1918) and some facilities of the assembly plant opened in Yokohama in 1912 by the Swiss watchmaker Rodolphe Schmid.
The brand Citizen was first registered in Switzerland by Schmid in 1918 for watches he sold in Japan. The development of this brand was supported in the 1920s by Count Gotō Shinpei with his hope that watches could become affordable to the general public. The growth of Citizen until World War II relied on technology transfer from Switzerland.
