Citizen - Watch

Aviation, diving, Watches for men
Citizen (Citizen Holdings Co., Ltd. ) is the core company of a Japanese global corporate group based in Tokyo, Japan. The Citizen company was originally founded as Shokosha Watch Research Institute in 1918 and is currently known as the manufacturer of CINCOM precision lathe machine tools as well as CITIZEN watches. The trade name originated from a pocket watch CITIZEN sold in 1924. It is one of the world's largest producers of watches.
Citizen Eco-Drive watches
In the United States, Citizen is best known for its Eco-Drive range of watches. Eco-Drive watches use a battery recharged by a solar panel hidden under the watch face. In the rare and discontinued Eco-Drive Duo series, the solar power was supplemented by an automatic quartz power source. There was also an Eco-Drive Thermo model that exploited temperature differentials between the wearer's skin temperature and ambient temperature to recharge the battery. However, the only Eco-Drive system currently described on the Citizen Watch Official Web Site is the one depending solely on light to recharge. The Eco-Drive feature is similar to the Tough Solar battery charging system used in G-Shock watches by Casio. All Citizen Eco-Drive models are made in Japan but may also be assembled in China.

Skyhawk A-T line of watches features Atomic Timekeeping with radio-controlled accuracy. The watches can synchronize with atomic clocks in Japan, North America, and Europe and will automatically select the correct frequency for doing so based upon location of home time zone. The watch actually tracks two time zones--home and world--but synchronizes to the 'home' zone. When traveling, the user may swap the 'home' and 'world' zones--thereby enabling proper time signal reception on a different continent while retaining the other time. Note that day, date, and Daylight Saving Time settings are also set automatically when the watch is synchronized.
These features are comparable to the synchronization with atomic clocks found in Casio Wave Ceptor watches.
Citizen also manufactures watches for collectors. For example, a watch bearing the colors and logo of the Blue Angels. This watch is part of the Skyhawk A-T line, which utilizes Eco-Drive as its primary power source and features Atomic Timekeeping. The bezel of the watch includes a slide rule useful for calculating time, distance, speed, conversions, and other computations useful for pilots. The Blue Angels use blue and gold as their trademark colors and the watch bears this color scheme.
