Estimated amount of power generated by wearing the watch (Automatic generating system)
● By wearing the watch for one day (12 hours), the power reserve to run the watch for approximately a day and a half can be additionally charged.
※ In general, if you wear the watch for 12 hours a day for one week, the power reserve to run the watch for approximately 10 days will be additionally charged.
● If the period you wear the watch per day is not long enough, observe the Direct Drive indicator
hand to check the amount of power reserve. If necessary, charge the watch by turning the crown.
※ “How to read the Direct Drive indicator hand” page 66 “How to charge the watch” page 64
［One-Way 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.
How to use the rotating bezel
By setting the rotating bezel beforehand, the elapsed time since the start of an event can be measured.
Read the graduation on the rotating bezel to which the minute hand is pointing.
2
At the start of the event, 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.

※ The rotating bezel is designed to rotate only counterclockwise. Do not forcibly rotate it clockwise.

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.

TO PRESERVE THE QUALITY OF YOUR WATCH
The function of the Direct Drive indicator hand involves complex movements, for example, to display the power generating
status during the power generation. Therefore, the position of the Direct Drive indicator hand may move out of alignment
in rare cases, but the watch automatically corrects the position of the Direct Drive indicator hand once every 24 hours.
● About the movement of the Direct Drive indicator hand during automatic hand alignment
When automatic hand alignment starts, the Direct Drive indicator hand moves down to the area
below 0 and remains there wiggling, and then points at 0 in the end. After automatic hand alignment
is completed, the Direct Drive indicator hand returns to display the amount of power reserve.
The Direct Drive indicator
hand wiggles around the
area below 0.
