ENERGY DEPLETION FOREWARNING FUNCTION
●
When the second hand starts moving at two-second intervals instead of the normal one-
second intervals, the watch will run down in approximately 24 hours.
In this case, swing the watch from side to side to charge the KINETIC E.S.U. sufficiently.
* The watch remains accurate even while the second hand is moving at two-second intervals.
INSTANT-START FUNCTION
●
When a long time has passed since the watch stopped, you can get it started quickly with
only a few swings.
●
This function is available as long as the watch has been stopped for less than a year.
* When this function is activated, the second hand will start moving at two-second intervals. Swing the
watch from side to side to charge the KINETIC E.S.U. by referring to “NUMBER OF SWINGS AND POWER
RESERVE”.
* After the second hand starts moving at one-second intervals, put the watch on your wrist so that it will be
charged further.
* The watch remains accurate even while the second hand is moving at two-second intervals.
REMARKS ON THE KINETIC E.S.U.
●
The electric energy generated while the watch is worn on your wrist is stored in the KINETIC
E.S.U. It is a power source completely different from conventional batteries for watches and
does not require any periodical replacement.
