Watch is a precision timing devices, easy to make, after encountering strong vibration mechanical deformation, the watch will run error occurs even stop and go. Citizen companies started to develop from the early 50's earthquake watch, the success in 1956 and conducted the experimental air fall, this sensation of the world.
In1962, developed the world's thinnest mechanical three-pin watch.
In 1966, the early development of electronic watches, Japan.
In 1975, the world's first error is less than three seconds on Analog quartz watch.
In 1976, developed a solar-powered Analog quartz watches.
In 1978, the world's first dual-display with digital and quartz watches pointer.
In 1978, the first thickness of only 0.98 mm of the world's thinnest quartz watch movement.
In 1980, the smallest of the world's first quartz watch Analog.
In 1995, launched the first solar-powered Citizen Watches.
In 1997, the error within 10 seconds of high-precision light energy table.
In 2003, the world's thinnest light powered watch, the thickness of only 4.4 mm.
March 2006, Citizen Watch Company in Basel, Switzerland at the launch of the world's first solar-powered three repeater watch.
