Calibrating the High Tide Time
You obtain more accurate tide indications by the watch by calibrating its high tide time with information
you can fi nd on the Internet or in a newspaper.
• Note that the high tide time differs according to your location and the current season.
To calibrate the high tide time
1. Perform steps 1, 2, and 3 under “To view the tide level and Moon age for a specifi c date and time” and
then specify the date whose high tide time you want to calibrate.
2. Pull out the crown.
• This will cause the hour and minute digits of the high tide time to
fl ash.
3. Rotate the crown to change the minute setting.
• The hour setting will change in accordance with minute setting
changes. To set the hour hand separately, go to step 4 of this
procedure.
• Any time during steps 3 through 5, you can discard your changes
and return to the uncalibrated high tide time for the selected date
by pressing
A
and
C
at the same time.
• If there are two high tides on a date, set the time of the fi rst high
tide. The watch will automatically calculate the time of the second
one.
• If summer time is turned on for your Home Time ( DST displayed),
you should also use summer time when setting the high tide time
(page E-36).

You can also check information for another city by changing to a different Home City (page E-36).
• Note that the tide and Moon information displayed by this watch is approximate and is intended as
general information only. Never try to use it for marine navigation or any other purposes requiring
accurate measurements.
To view the current tide level and Moon age
The small hand indicates the tide level.*
* Except in the Compass Mode, Altitude Mode, or Barometer Mode, or
while the crown is pulled out.
In the Tide/Moon Mode, the tide level for a specifi ed date and time is
indicated. See the information starting from page E-92.
• The tide level is indicated as one of six levels.
• The tide in the Home City is indicated even while the watch is in the
World Time Mode.
• If the Tide Graph hand indication is not correct, check the Timekeeping
Mode time and date, and the Home City settings. If this does not
correct the problem, refer to “Calibrating the High Tide Time” (page E-95).
