CAUTION
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.

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.
