Welcome to SeikoKinetic.net
Seiko Kinetic watches out in the past that relied on the movements of your body (particularly the wrist) to generate energy so that it continues to function, and this tradition will continue with the last Kinetic. Not only it keeps energy in reserve through the movement of your body, but it also has the function Direct Drive which allows those who are turning the winding to power the device. The wearer of the watch can see the energy transfer in real time, enabling him to know how much energy has been transferred. I suppose that watches such as these would be perfect for those who practice a daily sports like tennis and badminton, as the amount of movement involved would probably mean that you never touch the winding.
