The Japanese watch manufacturer Citizen began its history as the Shokosha Watch Research Watch Institute, whose 1924 pocket watch was christened the Citizen by the mayor of Tokyo. In 1930, the Citizen brand was repurposed as the name of the company, and in 1931, Citizen produced its first wristwatch, the Caliber F. In 1956, the company introduced the first Japanese shock-resistant wristwatch, the Parashock, and in 1959, it launched the island nation’s first water-resistant model, the Parawater. Other Citizen milestones include the manufacture of Japan’s first electronic wristwatch, the X-8, in 1966, followed in 1967 by the launch of the world’s first transistorized electronic quartz clock, the Crystron.
