※The crown is a screw lock type crown. To operate the crown, unlock the crown by unscrewing
it. Keep the crown locked unless it is necessary to operate the crown.
When screwing the crown in, turn it slowly with care, ensuring that the screw is properly
engaged. If it is stiff and difficult to work, unscrew it and redo it. Be careful not to forcibly
tighten the screw, as doing so may damage the screw.

WARNING

※Although the rotating bezel is removable by design for easy maintenance, do
not attempt to unscrew the two upper screws. SEIKO assumes responsibility
for maintenance.

2. After unlocking the screw, slowly
turn the crown clockwise （the 12 o
48
clock direction）to wind the main-
spring. Take care not to press
down the crown.
※As for manual winding, if you give the
crown five full rotations, it provides the
power to run the watch for approxi-
mately ten hours.
※If the crown is turned counter-
clockwise （the 6 o clock direction） , the
mainspring of the watch will not be
wound.
■HOW TO SET THE TIME AND DATE, HOW TO USE THE TIME DIFFERENCE ADJUSTMENT FUNCTION
●HOW TO SET THE TIME
・When setting the date and time, ensure that the watch is working: the main spring
is sufficiently wound.
・If your watch has a 24-hour hand, it has two different types of 24-hour hand usage.
Since the time setting method differs according to the type of usage, please choose
the type before setting the time.
〈Type 1〉Simply using the 24-hour hand to show the 24-hour time as an AM/PM
50
indicator.
・This is the standard usage type for the 24-
hour hand.
・For instance, by setting the hour, minute and
24-hour hands to Japan time, even if you set
the hour and minute hands to display the time
of the place you are staying while traveling
abroad by using the time difference
adjustment function, you can easily check the
time in Japan with the 24-hour hand which is
quite convenient.
How to set the 24-hour hand as a regular 24-hour indicator〈When the type 1 usage is selected〉
1. Unscrew the crown by turning it counterclockwise（the 6 o clock direction） ,
and then pull it out to the second click.
※Pull the crown out when the second hand is at the 12 o clock position since the second
hand will be stopping on the spot.
※When setting the time, ensure that the watch is working:the mainspring is sufficiently
wound.

■HOW TO USE
（HOW TO WIND THE MAINSPRING）
This watch is a self-winding watch equipped with a manual winding mechanism.
・When the watch is worn on the wrist, the motion of the wearer s arm winds
the mainspring of the watch.
・When first using a stopped watch, it is recommended that you manually wind
the mainspring by turning the crown.
●How to manually wind the mainspring by turning the crown
1. The crown is a screw-lock type crown. Turn the crown counterclockwise （the
6 o clock direction）to unlock the screw.（When the screw is completely
unlocked, the crown is projected outward from its original position.）

※To check the winding state of the mainspring, refer to
POWER RESERVE INDICATOR on page 67.
※There is no need to turn the crown further when the mainspring is fully wound. The
crown can be turned without damaging the watch mechanism; it only winds the
mainspring free.

4. Gently turn the crown clockwise （the 12
o clock direction） while pressing it, until
it is screwed all the way in and locked.
※While screwing the crown in, the watch clicks as the mainspring is wound. This
should not cause any concern since this is caused by movement of the mainspring.
〈Type 2〉Using the 24-hour hand to indicate the time in a different time zone.
・By setting the 24-hour hand to the time of a place different from where you live
（somewhere with time difference） , this type uses the 24-hour and hour/minute hands
for dual time display.
・For instance, by setting the 24-hour hand to GMT while setting the hour and minute
hands to indicate Japan time, you can easily check GMT with the 24-hour hand at any
time.

current time.

＜Example＞
To set to 10：00 A.M., adjust the 24-hour hand to indicate 10 on the 24-hour scale （ 5 o
clock position） , and the minute hand to the 0 minute position.
To set to 6：00 P.M., adjust the 24-hour hand to indicate 18 on the 24-hour scale （9 o
clock position） , and the minute hand to the 0 minute position.
※Only the 24-hour and minute hands are to be set at this stage. The hour hand is to be
set later so it is not necessary to adjust the hour hand yet, even if it is indicating the
wrong time.
※The date may be altered depending on the position of the hour hand, however it
should not cause any concern since it can also be adjusted later.
※Set the minute hand behind the time and then slowly advance it to the desired time.
