■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.
Make sure that you check the correct remaining amount
CAUTION
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
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.

Diver adjuster
If your watch has a metal bracelet equipped with a diver adjuster
mechanism, you can easily adjust the bracelet length by yourself.
This is very useful when you wear the watch over a wetsuit or a
heavy winter clothing.

How to use the diver adjuster

① Lift up the flap approximately 90° and press it down further approximately
20°, and hold it there.
※ You may feel slight resistance, but doing this requires only a light force.
Please do not push the flap down forcibly.
② Lightly pull the bracelet on the 6 o'clock side of the watch along the curved
line of the bracelet.
※ Again, doing this requires only a light force. Please do not pull the bracelet forcibly.
※ The slider can be pulled out approximately 30 mm. Be careful not to pull it
out beyond the limit mark inscribed on it.
