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

Love It
I've owned Seko watches for more than 30 years, and have always marveled at how tough and accurate they are. When I was ready to buy a new Seiko, only because I wanted a little change in wrist jewelry, I concluded that this kinetic watch was among the most attractive by my standards of conservative elegance.

For example, the stainless steel markings on the watch face are highly refelective and they sometimes flash briefly as they catch the light - which adds just the right amount of pizazz. The clasp on the wrist band is a new post type (to me); it gives a very nice, positive latching action.

Last but not least, I love the "kinetic" winding - which means that I'll never have to buy a battery for this watch. I walk enough, and work out at the gym enough, so that within a few days the watch became fully charged, which according to the manufacturer, means that it had reserve power enough to last 6 months without any further motion. Goodbye watch batteries.

In summary - I love it. I would have rated it 5 stars if it displayed the day of the week as well as the day of the month.

Sleek!
I was looking for a nice, professional, and dependable watch. I am not enamored with extra bells and whistles. I want my watches to tell me the accurate time and date without the necessity of a battery or constant movement needed with automatics. I don't need a watch to tell me the month, whether its day or night, military time, nor the time of another time zone. Keep it simple and precise.

This watch has a very sleek design, has a good sized face without being clunky, and possesses the qualities of every Seiko Kinetic watch. I do not have to remove it to type or dictate. This will be the watch I will wear daily for the next several years.

Solid, accurate, practical
This is my first Seiko. I have a Citizen Eco-Drive dress watch but without illimunated hands/markers, a leather band, and no backlight. Also, as I travel frequently, the stem for it is very difficult to pull out which is a royal pain when switching time zones. My previous stainless "casual" watch just croaked. I had the battery changed years ago and opening the case apparently introduced enough moisture into the interior so that it has corroded over the past 5 years. So, wanted a stainless casual watch, comfy enough for daily wear, tough enough to wear all the time, minimal fluff (I just need to know what time it is) and self powering so that I don't have to worry about the above issue. This fits the bill very nicely and looks good enough that I can wear it to work as well. So far (1 week) very accurate and that's about all I ask from a watch. The stem appears to be big enough that I can change time zones as need too which is a bonus.

3 month update. Not much different from above. It's been accurate, dependable and I've gotten several compliments on it. Very heavy stainless steel body & band which I like - definitely a "manly" watch. I have quit thinking about it and started to rely on it being utterly accurate - which is very high praise indeed. The date window could be a little easier for 43 year old eyes to see at a glance, but that's me getting older more than the watch. Otherwise, it has been everything I expected. As above, my first Seiko, definitely not my last if it continues like this.

9 month update. See above. I have bifocals now so seeing the date is no longer an issue. I wear it daily, it keeps perfect time and I don't even think about it. Aboslutely 100% reliable to date. HIGHLY recommended.
