［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.
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.
