not a malfunction.

＜Example＞

To set the 24-hour hand to the time in London while setting the hour/minute hands to indicate Japan time

When the time in Japan is 10：00 A.M., it is 1：00 A.M. in London.

Set the 24-hour hand to indicate“1”on the 24-hour scale（between the 12 o’clock and 1 o’clock position）,

while the minute hand is at the“0”minute position.

※The time difference adjustment function serves only for a time in a different time zone area where the time

difference from Japan time is represented in one-hour increments.

※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.

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 SET THE DATE

・This watch is designed so that the date changes one day by turning the hour hand

two full rotations in the same way as“the time difference adjustment function”.

（Refer to “● HOW TO USE THE TIME DIFFERENCE ADJUSTMENT

FUNCTION”on page 63.）

・The date advances one day by turning the hour hand two full rotations clockwise,

while the date is set back one day by turning the hour hand two full rotations

counterclockwise.

・Set the date after setting the time. Manual date adjustment is required at the end of a

month that has less than 31 days： February, April, June, September and November.

1. Unlock the screw lock type crown by turning it counterclockwise（the 6 o

Tips for more accurate time setting

・ Take notice of the following points in order to set the time more accurately.

1. Before setting the time, wind the mainspring until the power reserve indicator

shows a full-wound state.

2. When using a watch after it has stopped, wait approximately 30 seconds after the

second hand starts moving, and then pull the crown out to the second click.

3. Do not stop the second hand with the crown being at the second click position for

thirty minutes or longer. If the time the crown has been at the second click position

and the second hand has been stopped exceeds 30 minutes, push the crown back in

to its original position, and let the second hand move for 30 seconds or longer, then

restart the time setting.
