Seiko Kinetic Watches offer a very unique selling point in that they don’t require a battery.  The concept behind this particular range of Seiko watches is that kinetic energy is converted into electrical energy using the natural movement on your hand.
This may sound like an extremely complicated processes, however it is actually very simple.  The movement of your hand oscillates a weight inside the watch and through the gear train drives the main motor by amplifying the rotational movement.  The inner workings of the Seiko Kinetic watch then converts this movement (kinetic energy) into electricity which is then stored using a capacitor, which is essentially acts as a small regargable battery.

Because this capacitor will continuously charge and recharge itself there is no need for a change in battery.  Because the Seiko Kinetic watch will never need to be opened, it is vacuum sealed to preserve the integrity of the inner workings.  The essential difference between batter, kinetic and solar powered watches is the means by which energy is drawn from and how it is transferred.
