DIVING MEASUREMENT
How to read the measurements
● The time submerged is the time when you descend to a depth of 1.6 m or more underwater, and the
diving time measurement starts at the same time.
● The time submerged is indicated in the 12-hour indication without showing AM/PM.
● The diving time can be measured and indicated for up to 12 hours, but it is only recorded for up to 2 hours
as the log data in memory.
● The DIVING TIME hand moves at 1/5-minute intervals, but the scale is graduated in minutes.
● Do not press buttons B and C at the same time.
How to use the diving function
● Even if you have never made a dive using the watch, log data of two dives is prerecorded in memory
for checking purposes.
● If you start a dive without resetting the hands to “0” position, they automatically return to “0”
position as the watch starts measuring and then move to indicate the depth and diving time.
However, you cannot check the current depth all this while, so therefore be sure to reset the hands
to “0” position before diving.
WARNING FUNCTION FOR DIVING
Rapid ascent warning
● If the diver ascends so fast that the DEPTH hand cannot move exactly in accordance with the actual
change of depth, the 1/10 m hand does not move back and forth but alternately moves and stops
as a warning.
Extra measurement range warning
● If a depth of more than 55.0 m is measured, the log data recorded in memory will be as follows:
