Citizen began in 1918 as the Shokosha Watch Research Institute, set up to make watches in Japan, and became a company in 1930. A year later it completed its first wristwatch. In 1976 it launched the Crystron Solar Cell, the first analogue quartz watch with a solar cell, which opened the way to Eco-Drive. That light-powered technology is its hallmark today, along with the professional Promaster line. Bulova has been part of the group since 2008.
