Kinetic: A powerhouse in technological innovation

Like mechanical and quartz, Kinetic is a platform. Over the past 20 years, SEIKO has created on this platform a suite of Kinetic movements, each bringing unique features to the consumer.

It was at the 1986 Basel Fair that SEIKO unveiled its first Kinetic prototype. Introduced under the trial name of 'AGM', it was the first watch in the world to convert kinetic movement into electrical energy. It was the first step in a development that, 20 years later, has made Kinetic synonymous with environmental friendliness, high performance and long-lasting convenience to a generation of users worldwide. From the launch in 1988 of the first commercially available watch (then under the new name AGS) until today, over eight million Kinetic watches have been sold (as of 2007).

In 1998, Kinetic Auto Relay was released, extending the 'at-rest' operating period of the watch to a remarkable 4 years. 1999 saw the launch of the Ultimate Kinetic Chronograph, a masterpiece which fused the very best of SEIKO's mechanical and electronic watch making skills, and in 2003 another Kinetic Chronograph was launched. At Baselworld 2005, the Kinetic Perpetual made its first appearance, combining Kinetic convenience and longevity with a perpetual calendar, correct to the year 2100. In 2007, SEIKO's emotional technology Kinetic Direct Drive is introduced.

Customer Reviews

Superb Watch, Looks Like New After 5 Years.
My wife bought me this watch almost five years ago. It has worked flawlessly and still looks like new.
It is the most accurate watch I have ever owned. It gains about 1 second every 2 months. The Kinetic charging system always has 6 months of charge.
You will find yourself moving your arm to hear the reassuring rotor sound as the watch charges up.
The nicest thing is that is goes well with my wedding ring. Just enough gold to look nice, but not gaudy. The gold plating must be pretty thick. Even on the bottom the band, where it rubs the desk when I am typing looks like new. The band does not pinch or grab your arm hairs. The clasp has never come loose.
If you look at a Grand Seiko, which runs about $1,000 more, it has almost the same band, without the gold.
Ladies, if you buy the man in your life this watch, he will not be disappointed.
Men, if you want a reliable watch that looks even more expensive than it is, choose this watch.

Fine Timepiece
I had been after my husband for several years to get a new watch. His was clunky, scratched and just ugly - plus the clasp kept coming undone every hour or so. I finally decided to take the decision out of his hands and went looking for a new watch as a Christmas gift. I had no inclination to drag all over Houston looking at every watch emporium so Amazon seemed to be the best option for shopping from my computer. I was blown away by the huge selection and had no trouble at all finding exactly what I was looking for. It is a two-tone Seiko kenetic watch and he just loves it. He said it is much nicer than what he would have bought for himself. What more could I ask for...?

Cool watch
I've had mine for several month and I like it very much. It looks great, no need to wind it or change batteries. Very nice product.
