Unlike the conventional quartz watch powered by the button-type battery,
the SEIKO KINETIC is equipped with an automatic power generating system
developed by SEIKO. It generates the electrical energy to power the watch,
utilizing the movement of the arm or wrist, and stores it in a KINETIC E.S.U.
So the watch does not use a battery, and the battery replacement procedures
are completery elimminated.
The watch features a power reserve indicator function that shows with
the movement of the second hand how many days of power reserve is stored
in the KINETIC E.S.U.
If fully charged, the watch will keep operating for more than 6 Months
