Citizen Watch Co., Ltd. (??????????, Shichizun tokei Kabushiki-gaisha) is the core company of a Japanese global corporate group based in Tokyo, Japan. The company was founded as Shokosha Watch Research Institute in 1918. It is known as the manufacturer of Cincom precision lathe machine tools and Citizen watches. The trade name originated from a pocket watch Citizen sold in 1924.

Atomic timekeeping
Citizen launched the world's first multi-band Atomic Timekeeping watch in 1993, and has remained a pioneer of this field. They combined it with their light powered Eco-Drive technology so when you own a Citizen Atomic Timekeeping watch you will get the precise time powered by any light source. With a margin of error of just one second in 100,000 years, Citizen watches receive radio signals from an atomic clock to set the time correctly.
Some watches, such as the Skyhawk A-T line feature radio-controlled timekeeping. The watches can synchronize with radio 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. The 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.
The Perpetual Chrono A-T is another of Citizen's radio-controlled watches. The watch syncs with the atomic clocks in Colorado or Germany depending on signal strength and location. It also incorporates the eco-drive technology which means it will never require a battery.

Bulova UHF movement
In 2010, Miyota (Citizen Watch) of Japan introduced a newly developed movement (UHF 262 kHz) that uses a three-prong quartz crystal for the Precisionist or Accutron II line, a new type of quartz watch with ultra-high frequency (262.144 kHz) which is claimed to be accurate to +/- 10 seconds a year and has a smooth sweeping second hand rather than one that jumps each second.
Chronomaster
The Chronomaster line of watches are a series of High Accuracy Quartz watches produced by Citizen. The Chronomaster is unofficially the most accurate watch ever made, with an accuracy of +5/-5 seconds per year. They are currently sold only in the Japanese Domestic Market, but can be shipped out of Japan if ordered online.
Contemporary watches
Citizen also produces the Independent Watches line, featuring a more modern, contemporary design than the traditional Citizen label. Depending on the market, these watches may be labelled "Secret", "Lighthouse" brands among others.
DCP clasp
The Deployant Clasp with a Push Button (DCP) is a clasp available for many Citizen watch bracelet bands. The clasp, as with the Calibre 8700, is also used with leather bands as if they were metal bracelet-style watchbands; however, when the clasp is fastened, the band appears to be a normal eye-hole and link pin leather watchband.
Eco-Drive
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. One early model, called the Citizen Vitality, used the watch hands to drive a small electric generator, but was discontinued following complaints that the device could explode and cause wrist injuries. 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 described on the Citizen Watch official web site is the one depending solely on light to recharge. Features similar to the Eco-Drive have been developed by other manufacturers like Casio and Junghans. All Citizen Eco-Drive movements are made in Japan but the case or the bracelet may also be made in China.
Q&Q SmileSolar
Q&Q SmileSolar are a line of solar powered watches, which do not require a battery change. They are made of recycled materials and have a water resistant rating of 10 Bar. The line of watches also supports people by making a donation for each watch purchased.
Other products
Citizen also manufactures calculators and small electronic organizers. Some non-watch devices such as handheld televisions and computer printers, have been marketed under the Citizen brand name.
In the 1980s, a number of handheld electronic games were sold under the Q&Q brand.
In the early-mid 1990s, Citizen partnered with Compaq Computer Corporation to build notebook computers in Japan for the Japan and Far Eastern market to be sold under the Compaq name.
On January 10, 2008, Citizen bought the Bulova Watch Company for $250 million, making The Citizen Group the world's largest watchmaker.
In 2016, Citizen acquired the Swiss Frédérique Constant Group.
