SEIKO KINETIC AUTO RELAY Cal.5J21 is an analogue quartz watch equipped with an
Automatic Generating System developed by SEIKO. It generates the electric energy to power
the watch, utilizing the movement of the arm, and stores it in the KINETIC ELECTRICITY
STORAGE UNIT (KINETIC E.S.U.). So, the watch does not use a conventional button-type
battery and does not require battery replacement.

Cal.5J21 is an enhanced model of the KINETIC watches and features the power save and time
relay functions to keep the watch operating for up to four years once it is fully charged, even
if it is left unused and no charging is done.

Manual power save function

The power save function can be activated manually. If you decide not to use the watch
for a long time, use this function to further conserve energy.

POWER SAVE FUNCTION

● If the watch is left untouched for approximately 3 days, the hands will stop moving to

minimize the electrical energy consumed.

● More specifically, the power save function is activated if the generating system of the watch

remains inactive and no charging is done for approximately 72 hours.

● Even if the watch is not worn for more than 3 days, the power save function will not be

activated if the watch senses enough activity to start the generating system working during
the 3 days.

● Though the hands stop, the built-in IC continues to compute the time.

* While the second hand is moving at two-second intervals, the power save function cannot be

activated manually. In this case, charge the watch referring to “ENERGY DEPLETION FOREWARNING
FUNCTION”, and then, follow the procedure below.

Note: If your watch has a screw lock type crown, turn the crown counterclockwise to unscrew it, and

then, pull it out. After using the crown, push it back in to the normal position, and then, turn it
clockwise to screw it in completely.

Caution:

Do not pull out the crown to the second click while the power save function is in
operation. Otherwise, it is turned off, and the time data retained inside the watch
will be erased, thus disabling the time relay function.
