2. CHARACTERISTICS OF MANUAL WINDING FUNCTION OF KINETIC DIRECT DRIVE
1. As for mechanical watches, the amount of power generated increases in proportion to the
number of times the mainspring is wound. As for the KINETIC DIRECT DRIVE watches, however,
the amount of power generated by manual winding varies depending on the speed and length of
strokes in which you wind the crown.
The more efficiently the power is generated, the more the direct drive indicator hand moves.
It is even possible to reach the maximum scale value of power reserve with only one stroke.
2. The size of the crown will also affect the amount of power generated by manual winding.
Even if the crown is turned in exactly the same manner, the amount of power generated will vary
depending on the size or the shape of the crown.
Generally, the smaller the crown is, the more efficiently the watch can generate the power.
Functions by button operation
* Do not set the moon phase between 9 pm and 1 am,
as the moon phase may not change to the correct
display on the following day.
System reset (No power is generated.)
If any improper function occurs, for example, the direct
drive indicator hand stops moving while it is pointing
anywhere other than the standby position, follow the
instruction below to reset the built-in IC.
1. Pull out the crown to the second click.
2. Press the button at the 10 o'clock position for 2
seconds or more.
3. Push the crown back into the normal position.

After pushing the crown back into the normal position,
charge the watch by manual-winding method and check
that the hands start moving. At the same time the hands
start moving, the direct drive indicator hand will return
to point at the 0 position, and the watch will resume its
normal operation.
After the built-in IC is reset, the continuous operating
time is cleared and the direct indicator hand points at the
0 position. If no power is generated subsequently, the
watch will stop operating within three minutes. In order to
avoid this, charge the watch at least until the direct drive
indicator hand points at the first indication on the dial. It is
also recommended that you correct the position of direct
drive indicator hand manually as instructed on page 3.
