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, the
Moon and the 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.
E-52
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”.

Auto Return
If you do not perform any operation for about two or three minutes while a setting
screen (with a flashing setting) is on the display, the watch will exit the setting screen
automatically.
Scrolling
The B and D are used in various modes and setting screens to scroll through data
on the display. In most cases, holding down these buttons during a scroll operation
scrolls at high speed.
Initial Screens
When you enter the World Time Mode or Alarm Mode, the data you were viewing
when you last exited the mode appears first.

Timekeeping
• Resetting the seconds to 00 while the current count is in the range of 30 to 59
causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are
reset to 00 without changing the minutes.
• The year can be set in the range of 2000 to 2099.
• The watch’s built-in full automatic calendar makes allowances for different month
lengths and leap years. Once you set the date, there should be no reason to change
it except after you have the watch’s battery replaced.
• The current time for all city codes in the Timekeeping Mode and World Time Mode is
calculated in accordance with the Coordinated Universal Time (UTC) for each city,
based on your Home City time setting.
World Time
The seconds count of the World Time is synchronized with the seconds count of the
Timekeeping Mode.
