When barometer hand “2” indicates greater numbers such as “9”, barometer hand “1” gets close to
the next graduation of the scale. In the example above, take care not to read the indication as
“959”.
When barometer hand “2” indicates smaller numbers such as “0”, barometer hand “1” may seem to
indicate the position slightly before a graduation. For example, take care not to mistake “950” for
“940”.

To know the current atmospheric pressure: 5 second-interval measurement for 5 minutes
The watch automatically measures the time at 10-minute intervals, and the barometer hands keeps
indicating the same measurement for 10 minutes.
5-second interval measurement mode is useful in case you wish to know the current atmosperic
pressure or in case the atmospheric pressure changes greatly in a short time.
The 5-second interval measurement mode can be started only by pressing button C. It continues
operating for 5 minutes.
(1) Press button Cto start the 5-second interval measurement mode.
(2) The watch will resume the 10-minute interval measurement in 5 minutes.
[To cancel the 5-second interval measurement mode]
To cancel the 5-second interval measurement mode, press button Bto recall the minimum atmospheric
pressure retained in memory. (For details, refer to “How to recall the minimum atmospheric pressure”.)
How to recall the minimum atmospheric pressure/maximum approximate altitude
The watch automatically retains in memory the minimum atmospheric pressure measured, and it can
be recalled as required.
On the sea, this function is useful when you encounter an atmospheric depression.
On land, this function serves as the record of the maximum approximate altitude when you climb a
mountain.
The minimum atmospheric pressure in memory can be erased as required.
(1) Press button Bto recall the minimum atmospheric pressure in memory. The two barometer hands
move to indicate it, and the confirmation sound beeps.
As button Cis pressed, the watch measures the atmospheric pressure immediately. After the
measurement is shown, a confirmation sound will beep.
To continue the 5-second interval measurement, press button Cagain.
If button Cis pressed successively, the 5-second interval measurement continues for 5
minutes after the button is pressed lastly.
