Vintage watch Seiko kinetic working condition from 1990s
Seiko Kinetic combines the principle of power supply
in 2 mechanical movements Automatic and Quartz
watches. In a Kinetic watch movement,
kinetic energy from the movement of the arm
(when wearing the watch) causes the rotor to rotate,
creating energy.
The generated electricity is stored in a rechargeable battery
that requires replacement less frequently
than the conventional cell battery in a quartz watch.
