Charging Precautions
Certain charging conditions can cause the watch to become very hot. Avoid leaving
the watch in the areas described below whenever charging its rechargeable battery.
Also note that allowing the watch to become very hot can cause its liquid crystal
display to black out. The appearance of the LCD should become normal again when
the watch returns to a lower temperature.
Warning!
Leaving the watch in bright light to charge its rechargeable battery can cause it
to become quite hot. Take care when handling the watch to avoid burn injury.
The watch can become particularly hot when exposed to the following
conditions for long periods.
•
On the dashboard of a car parked in direct sunlight
•
Too close to an incandescent lamp
•
Under direct sunlight

Charging Guide
The following table shows the amount of time the watch needs to be exposed to light
each day in order to generate enough power for normal daily operations.
•
For details about the battery operating time and daily operating conditions, see the
“Power Supply” section of the Specifications.
•
Stable operation is promoted by frequent exposure to light.

functions of this watch.
Moon Phase Indicator
The Moon phase indicator of this watch indicates the
current phase of the Moon as shown below. It is based on
the view of the left side of the moon at meridian transit
from the northern hemisphere of the Earth. If the
appearance of the Moon phase indicator is reversed from
the actual Moon as viewed from your location, you can
use the procedure under “To reverse the displayed Moon
phase” to change the indicator.

Tidal Movements
Tides are the periodic rise and fall of the water of oceans, seas, bays, and other
bodies of water caused mainly by the gravitational interactions between the Earth,
Moon and Sun. Tides rise and fall about every six hours. The Tide Graph of this watch
indicates tidal movement based on the Moon’s transit over a meridian and the lunitidal
interval. The Tide Graph calculates and graphically represents current tide conditions
in your Home City or a port city in the vicinity of the Home City based on longitudes,
lunar day length, and lunitidal interval preset in watch memory, and on high tide times
specified by you.
Tide Graph
The Tide Graph graphically represents the current tide condition using one of three
patterns that represent spring tide, intermediate tide, and neap tide, as shown below.
Large difference between high tide
and low tide. Occurs a few days
before and after a New Moon and Full
Moon.
Medium difference between high tide
and low tide.
Small difference between high tide
and low tide. Occurs a few days
before and after the first quarter and
last quarter of a half moon.

•
The Tide Graph flashes as shown below to indicate the tide range.
•
The segments on either end of the Tide Graph flash during high tide.
Lunitidal Interval
Theoretically, high tide is at the Moon’s transit over the meridian and low tide is about
six hours later. Actual high tide occurs somewhat later, due to factors such as
viscosity, friction, and underwater topography. Both the time differential between the
Moon’s transit over the meridian until high tide and the time differential between the
Moon’s transit over the meridian until low tide are known as the “lunitidal interval”.
