Key Features

As this watch has never been worn, it is in pristine condition. So pristine, in fact, that there is still a protective film seal on the caseback. The dial, hands, case and bracelet are all in perfect working order and virtually flawless. No servicing was needed because of this. There are minor traces of storing and handling marks on the bracelet and case, and there is a tiny scratches on the crystal near the 1 position, but these are almost imperceptible. Features a date function at the 3 position and a cool slightly tapered bracelet with a signed micro-adjustment clasp.

About Citizen

Citizen is, strictly speaking, an electronics company, but they are best known as a watch manufacturer. The company was founded in 1930 by Japanese and Swiss investors. Among some of Citizen’s personal achievements in watchmaking are; the development of radio-controlled atomic watches that could be synchronised to an atomic clock that was accurate to within one second in one hundred thousand years, a three pronged quartz movement that claimed to be accurate within +/- 10 seconds a year and had a sweeping seconds hand, and the Eco-Drive watches that ran on solar power with a supplementary quartz movement.
