HOW TO USE
(For Cal. 9R84, 9R65, 9R15)
How to wind the main spring
○ This watch is an automatic winding type (with manual winding
function).
○ The mainspring can be sufficiently wound automatically by natural
movement of the arm while it is worn on the wrist. In addition, the
mainspring can be wound by turning the crown. Please see the power
reserve indicator to check the level of the remaining power.
⇒ "How to read the power reserve indicator" page 17.
○ When starting to use a stopped watch, it is recommended that you turn
the crown to wind the mainspring. To wind the mainspring, turn the
crown at the normal position clockwise (12 o'clock direction) slowly. If
you turn the crown counterclockwise (6 o'clock direction), it will turn
free. Five full rotations of the crown will provide the power to run the
watch for approximately ten hours.
○ If you wear the watch for twelve hours per day consecutively for three
to five days, the watch will be fully wound.
※ Under a low-temperature condition (below 0ºC), always keep at least one-sixth
of the watch power shown by the power reserve indicator.
CAUTIONS
○ Do not adjust the date when the time the watch indicates is between 9
p.m. and 1 a.m. If the date is adjusted in this condition, the date may
not change properly the following day, or a malfunction may occur.
○ If you set the date when the time the watch indicates is between 9:00
p.m. and 1:00 a.m., pull out the crown to the second click, and turn it
counterclockwise (downward) to advance the hour hand until it passes
1:00 a.m. temporarily, and then set the date.
How to set the time and date
This watch is equipped with the date display function. The date advances
one day once every 24 hours around midnight. Therefore, if AM/PM is
incorrectly set, the date will change around noon. When setting the date
and time, ensure that the watch is working.
① Pull out the crown to the first click. (If the watch is equipped with a
screw-lock type crown, unscrew
the crown before pulling it out.)
② The date can be adjusted by
turning the crown counterclockwise
(downward). First turn the crown
until the previous day's date from
the desired date appears.
【Ex.】 If you want to set the date to
''6,'' set the date to ''5'' by
turning the crown.

③ Pull out the crown to the second click when the second hand (or the
small second hand) is at the 0 position. The second hand (or the small
second hand) stops. Turn the crown counterclockwise (downward) to
advance the hands until the desired date appears. If the date changes,
it means that the watch is set in
the morning. Turn the crown
further until the watch is set to
the current time.
④ Push the crown back in to the
normal position in accordance
with a time signal. The watch
starts operating.
Date adjustment at the end of the month
It is necessary to adjust the date after February (which has 28 days, 29
days in a leap year) and a 30-day month.
【Ex.】 To adjust the date in the morning on the
first day of a month following a 30-day
month
On the first day of a 30-day month, ''31''
is displayed. Pull out the crown to the first
click. Turn the crown clockwise to set the
date to ''1,'' and push the crown back in
to the normal position.
For models with a screw-lock type crown, remember to screw
CAUTION
the crown in.
Tips for more accurate time setting
To ensure effective operation of the Spring Drive mechanism, observe the
following instructions when you set the time.
① Before setting the time, make sure to wind the mainspring sufficiently.
(Ensure that the power reserve indicator is showing a full-wound state.)
② When starting to use a watch after it stops, wind the mainspring sufficiently.
To set the time after that, wait for approximately 30 seconds after the
second hand (or the small second hand) starts moving, then pull the
crown out to the second click.
③ The second hand (or the small second hand) will stop moving when the crown
is pulled out to the second click. Do not stop the movement of the second hand
(or the small second hand) for longer than 30 minutes. If the stoppage of the
second-hand (or the small-second-hand) movement exceeds 30 minutes, push
the crown back in, and wait for approximately 30 seconds after the second
hand (or the small second hand) restarts moving, and then set the time.
