Home Site Data
Moon phase, tide graph data, and Moon/Tide Data Mode data will not be displayed properly unless Home Site data (UTC differential, longitude, and lunitidal interval) is
configured correctly.

• The UTC differential is a value that indicates the time difference between a reference point in Greenwich, England, and the time zone where a city is located.

• The letter “UTC” is the abbreviation for “Coordinated Universal Time”, which is the worldwide scientific standard of timekeeping. It is based upon carefully maintained
  atomic (cesium) clocks that keep time accurately to within microseconds. Leap seconds are added or subtracted as necessary to keep UTC in sync with the Earth’s rotation.

• The lunitidal interval is the time elapsing between the Moon’s transit over a meridian and the next high tide at that meridian. See “Lunitidal Interval” (page EN-45) for more information.

• This watch displays lunitidal intervals in terms of hours and minutes.

• The “Site/Lunitidal Interval Data List” at the back of this manual provides UTC differential and longitude information around the world.

• The following is the initial factory default Home Site data (Tokyo, Japan) when you first purchase the watch, and whenever you have the battery replaced. Change these settings to match the area where you normally use the watch. UTC differential (+9.0); Longitude (East 140 degrees); Lunitidal interval (5 hours, 20 minutes)

Reference

This section contains more detailed and technical information about watch operation. It also contains important precautions and notes about the various features and functions of this watch.
Moon Phase Indicator
The Moon phase indicator of this watch indicates the current phase of the Moon as shown below.

• The Moon phase indicator shows the Moon as viewed at noon from a position in the Northern Hemisphere looking south. Note that at times the image shown by the
  The Moon phase indicator may differ from that of the actual Moon in your area.

• The left-right orientation of the Moon phase is reversed when viewing from the Southern Hemisphere or from a point near the equator.
  Moon Phases and Moon Age
  The Moon goes through a regular 29.53-day cycle. During each cycle, the Moon appears to wax and wane as the relative positioning of the Earth, Moon, and Sun changes.

Tide Graph
The Tide Graph has six graphic segments, each of which indicates a different tide level. The current tide level is indicated by the displayed graphic segment.

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 lunitidal interval differs according to your current location, so you must specify a lunitidal interval in order to obtain the correct tide graph readings.

• The tide graph displayed by this watch is based on the current Moon age.
  Remember that the margin for error of the Moon age displayed by this watch is ±1 day. The greater the error in a particular Moon age, the greater the error in the resulting tide graph.

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”. When setting the lunitidal interval for this watch, use the time differential between the Moon’s transit over the meridian until high tide.

Button Operation Tone

Button Operation Tone
The button operation tone sounds any time you press one of the watch’s buttons. You can turn the button operation tone on or off as desired.

•  Even if you turn off the button operation tone, the alarm, Hourly Time Signal, and Timer Mode alarm all operate normally.

To turn the button operation tone on and off
In any mode (except when a setting screen is on the display), hold down C to toggle the button operation tone on ( not displayed) and off ( displayed).

• Holding down C to turn the button operation tone on or off also causes the watch’s current mode to change.
• The indicator is displayed in all modes when the button operation tone is turned off.

Auto Return Features

•  If you leave a screen with flashing digits on the display for two or three minutes without performing any operation, the watch automatically exits the setting screen.
• If you leave the watch in the Moon/Tide Data or Alarm Mode for two or three minutes without performing any operation, it automatically changes to the Timekeeping Mode.
  Scrolling
  The B and D buttons 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 through the data at high speed.

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.

Illumination Precautions

• Illumination may be difficult to see when viewed under direct sunlight.
• Illumination turns off automatically whenever an alarm sounds.
• Frequent use of illumination runs down the battery.
