Amazon.com Product Description
This Seiko Kinetic Auto Relay watch combines modern aerodynamic styling with advanced technological design. Powered by kinetic movement, it never needs a battery change. The watch holds a small oscillating weight, which is set in motion by the natural movement of your wrist. This motion generates a magnetic charge, which is then converted to electricity and stored in a tiny capacitor. On top of that, this watch is equipped with Seiko's unique Kinetic Auto Relay, which allows it to "sleep" for an extended period, and wake up to exactly the right time. If the watch senses inactivity for more than three days, it will place itself in suspended animation to conserve energy, yet it will continue to compute the time internally. Once you give it a shake, the watch will automatically reset to display the current time--even if it hasn't been worn for up to four years.
The round steel case is featured on an integrated steel link bracelet finished with a foldover clasp and safety mechanism. Luminous hands and markers lend nighttime visibility to the large round black dial, which also features a red sweep seconds hand and seconds indexes, bold Arabic numerals at the quarter hours, small Arabic minute markers, and a date display at four o'clock. The features of the dial combine to create simplicity, ease, and a quick and precise read off. Other notable features of this watch include a virtually scratch-proof sapphire crystal and water resistance to 100 meters.
About Seiko
In 1877, at the age of 18, Kintaro Hattori set up business repairing the Western-style clocks that were becoming increasingly popular in Japan. By 1892, Hattori was manufacturing his own clocks in a factory he called Seikosha, from the words "seiko" meaning "exquisite," "success," or "miniature," and "sha" meaning "house." The company grew and prospered, producing its first wristwatch in 1913 and launching the Seiko brand in 1924. Technological innovation has always been a driving force in the company's history. Key milestones include Seiko's introduction of the world's first quartz watch in 1969, and its successful launch, in 1988, of the Kinetic, the world's first battery-free watch with quartz accuracy. Recognized for its technological excellence, Seiko has provided timekeeping services for the Olympic Games and the World Cup Soccer Championships. Today, the Seiko brand continues to stand for state-of-the-art technology, as well as superior quality and refined design.
