Seiko Kinetic Watches

Seiko kinetic watches make use of an intriguing technology to ensure that your watch will never need to have its battery replaced. Here's how it works. Every movement of your wrist during the course of your ordinary activities rotates a tiny oscillating weight inside the watch. A gear train amplifies the rotations by 100 times and transfers it to a rotor.

In the rotor, which can spin 100,000 RPMs faster than a Formula One race car, that rotation is turned into a magnetic charge. Then a coil transforms the magnetic charge into electricity. That electrical energy is stored in a "kinetic energy unit," which takes the place of a standard battery.

A quartz crystal oscillates at a rate of 32,768 times per second, then passes the electrical signal to a step motor. The step motor converts the electrical signal to a rotational motion. That is transmitted through the gear train to power the hands. All of this happens in a case roughly the size of a fifty-cent piece.

Seiko Kinetic Watches Offer Sophisticated Styling

There are several collections of Seiko kinetic watches. Though none are specifically styled for women, there are several models that can serve as unisex designs. Recently there has been a new addition to the line of Seiko kinetic watches, as kinetic dive watches are now being sold in the U.S. for the first time.
