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 seconds hand starts moving,
then pull the crown out to the second click.
3
The seconds hand will stop moving when the crown is pulled out to the second click. Do
not stop the movement of the seconds hand for longer than 30 minutes. If the stoppage
of the seconds hand movement exceeds 30 minutes, push the crown back in, and wait
for approximately 30 seconds after the seconds hand restarts moving, and then set the
time.

CAUTION
For models with a screw down crown, remember to screw the crown in.

HOW TO USE HOW TO USE
■ FUNCTIONS OF DIVER’S MODEL
Unidirectional rotating bezel
By using the rotating bezel, you can measure the elapsed time since the start of an
event or an activity such as diving.
This watch has a unidirectional rotating bezel. As the evaluation of the remaining air in your
cylinder is based on the information of the elapsed time of the dive, the rotating bezels for a
diver’s watch is designed to rotate only counterclockwise, so that the watch is prevented from
displaying the elapsed time shorter than it actually is.
b
CAUTION
Make sure that you check the correct remaining amount of air in your
cylinder before diving. Use the display of the elapsed time by the
rotating bezel only as a guide during diving.
How to use the rotating bezel
1
At the start of the activity, for which you want to measure the elapsed time (for example,
when you start diving), rotate the bezel so that the mark on the bezel is aligned with
the minute hand.
2
Read the graduation on the rotating bezel to which the minute hand is pointing.

Ex.
】
When you start diving at 10:10.
