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:
