SEIKO Kinetic Direct Drive Cal. 5D88 is an embodiment of the SEIKO’s ‘emotional technology’.
The watch features new functions but the knowledge of repairing the existing KINETIC series
will be helpful.
To repair the Cal. 5D88, therefore, you are requested to have the full knowledge of its functions
and strictly observe the repairing and checking instructions provided in this guide so that the
watch will be correctly repaired.
FEATURES
1. DISPLAY AND HOW TO USE
The Cal. 5D88 is a KINETIC watch equipped with two winding functions and two indicator
functions.
l
Two winding functions
As in all existing Kinetic calibers, the wearer automatically generates the electrical
energy by her/his wrist movement. With Kinetic Direct Drive, however, the wearer can
also generate energy by winding the crown.
l
Tw
o indicator functions
Kinetic Direct Drive shows not only the power held in reserve but also the level of power
generation when the wearer hand-winds the crown. The wearer can see and feel, in real
time, the direct transfer of power from his or her winding of the crown to the reserve.

The watch automatically corrects the position of the
direct drive indicator hand once ever y 24 hours. While
correcting its position, the direct drive indicator hand
automatically moves, but it is not a malfunction.
How to manually correct the position of the direct
drive indicator hand
• The position of the direct drive indicator hand can be
also corrected by hand.
1. Pull out the crown to the first click.
2. Press the button located at the 10 o’clock position for
2 seconds or more.
By doing this, the direct drive indicator hand returns
to the standby position.
3. Press the button at the 10 o’clock position to set the
position of the direct drive indicator hand pointing
exactly to the 0 position.

With each pressing of the button, the direct drive indicator
hand moves up the scale by one increment. By pressing
the button, adjustment can be made upto the second
increment. At the third pressing of the button, the direct
drive indicator hand returns to the standby position. Repeat
the procedures until the direct drive indicator hand is
correctly aligned to the 0 position.
How to set the Moon Phase
• The moon phase represents the period from the time
when the last new moon occurred to noon of the
current day in day increments.
• The period between new moons is called a “synodic
month,” and its average length is approximately 29.5
days.
* Round off the number of moon phase to the nearest
whole number (Example: 7.8, 8, 24.2, 24)
* Refer to the weather report of your local newspaper
for current moon phase information.

2. CHARACTERISTICS OF MANUAL WINDING FUNCTION OF KINETIC DIRECT DRIVE
1. As for mechanical watches, the amount of power generated increases in propor tion 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.

* 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.
Second click • Time setting 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.
BEFORE STARTING REPAIR WORK ON CAL. 5D88A

3. HOW THE DIRECT DRIVE INDICATOR HAND WORKS
1. Power reserve indicator function
• Except when the crown is being turned to charge the watch, the direct indicator hand functions
as a power reserve indicator which shows how long the watch will keep operating within the
range between the minimum 3 hours and the maximum 1 month.
For more details, refer to
“ How to read the power reserve indicator” below.
• If the direct drive indicator hand indicates the 0 position, the watch will stop operating within 3
hours. When the watch stops, the direct drive indicator hand moves to the standby position to
show that the watch stops operating due to a power shortage.
• T
he direct drive indicator hand constantly displays the most up-to-date amount of stored
power. If the amount of stored power is increased by the wearer’s wrist movement or by the
manual crown windings, the direct drive indicator hand displays the increased amount of power
accordingly. On the other hand, if the watch is left unworn and the stored power is decreased
as the watch consumed some power during the time it is left unworn, the direct drive indicator
hand displays the decreased amount of stored power accordingly.
•
The
maximum amount of power reserve that the watch can store is the amount of power
reserve to keep the watch operating for one month. When more power is generated after the
watch already stores this maximum amount of power, the power generated is not further
accumulated, and the direct drive indicator hand shows the power reserve of one month.

*note 1 When the watch is charged by any other method than manual winding, such as using KINETIC
ENERGY SUPPLIER, the direct drive indicator hand may move in slightly slower motion.
*n
ote 2 The direct drive indicator hand will stop at the maximum scale value pointing at the ‘M+1’ position.
If the crown is turned after the direct drive indicator hand stops at the ‘M+1’ position, the watch
continues to accumulate power reserve, but the real-time power indicator function stops. If you
want to display the a
mount of generated power
, stop turning the crown, and after the direct drive
indicator hand returns to the power reserve display, start turning the crown again.
Wh
en the electric power is generated without interruption, for example when an electric charger
is used, the direct drive indicator hand will stop and remain pointing at the ‘M+1’ position.
*n
ote 3 After the direct drive indicator hand displays the accumulated amount of generated power, it
returns to the power reserve display.
(Caution)
To
enjoy the real-time powe r indic ator functio n, power gene ration by manu al wind ing is
recommended as it enables you to check the power generating status.
