• The tide graph shows tidal movements for the current date in accordance with the current time as kept in the Timekeeping Mode.

• The Moon phase indicator shows the current Moon phase in accordance with the current date as kept in the Timekeeping Mode.

• See “Thermometer” for details about the thermometer screen and temperature tendency graph.

Important!

• Be sure to configure the current time and date, and your Home Site data (data for the site where you use the watch) correctly before using the functions of this watch. See “Home Site Data” for more information.

Setting the Digital Time and Date

This watch is preset with UTC differential values that represent each time zone around the globe. Before setting the digital time, be sure to first set the UTC differential for your Home Site, which is the location where you normally will be using the watch.

• Note that World Time mode times are all displayed based on the time and date settings you configure in the Timekeeping Mode.

Home Site Data

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

• The UTC differential indicates the time differential with Greenwich, England.

• The letters UTC is the abbreviation for Coordinated Universal Time, which is the

world-wide 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.

1.In the Timekeeping Mode, hold down A until the seconds start to flash, which indicates the setting screen.

2. Press C once and the DST setting screen appears.

3. Press D to toggle between Daylight Saving Time (

displayed) and Standard Time (OF displayed).

4. Press A twice to exit the setting screen.

• The DST indicator appears on the Timekeeping, Tide/ Moon Data, Alarm, and Hand Setting Mode screens to indicate that Daylight Saving Time is turned on. In the case of the Tide/Moon Data Mode, the DST indicator appears on the Tide Data screen only.

• 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” for more information.

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

• The “Site/Lunitidal Interval Data List” provides UTC differential and longitude

information around the world.

• The following is the initial factory default Home Site data (T okyo, Japan) when you first purchase the watch and whenever you have the batteries replaced. Change these settings to match the area where you normally use the watch.

Tide/Moon data lets you view the Moon age and the Moon phase for a particular date, and tidal movements for a particular date and time for your Home Site.

• When you enter the Tide/Moon Data Mode, the data for 6:00 a.m. on the current date appears first.

• If you suspect that the Tide/Moon data is not correct for some reason, check the Timekeeping Mode data (current time, date, and Home Site settings), and make changes as required.

• See “Moon Phase Indicator” for information about the

Time

Thermometer

This watch uses a temperature sensor to measure temperature. A reading is taken during each even-numbered minute, and the result of the last reading is displayed on the thermometer screen. The watch also takes separate readings and stores them in memory for display in the temperature tendency graph, which can be viewed in the Timekeeping Mode. Measured temperature values are stored in memory for later recall when you need them.

Thermometer Screen

Thermometer

• You can select either Celsius (°C) or Fahrenheit (°F) units for the thermometer screen. See “To specify the temperature display unit” for more information.

• The thermometer screen displays temperature values in 0.1°C units (or 0.2°F units).

• The display range of the thermometer screen is –10.0°C to 60.0°C (or 14.0°F to

140.0°F).

• You can calibrate the temperature sensor if you feel that the displayed temperature

values are not correct. See “Temperature Sensor Calibration” for more information.

Important!

• Temperature measurements are affected by your body temperature (while you are wearing the watch), direct sunlight, and moisture. T o achieve a more accurate temperature measurement, remove the watch from your wrist, place it in a well ventilated location out of direct sunlight, and wipe all moisture from the case. It takes approximately 20 to 30 minutes for the case of the watch to reach the actual surrounding temperature.

Temperature T endency Graph

The watch also takes temperature readings at the top and the bottom of each hour and stores the results in memory for display on the temperature tendency graph. Depending on the current Timekeeping Mode time, the temperature tendency graph shows either the top of the hour measurements or the bottom of the hour measurements for the past 17 hours. From the top of each hour to the 29th minute, past top of the hour readings are shown in the graph. From the bottom of each hour to the 59th minute, past bottom of the hour readings are shown in the graph. Temperature tendency graph contents are updated every 30 minutes.

▲

Past 17 hours of measurement values

The horizontal axis of the graph represents time. The rightmost column is the newest temperature value in memory, while the leftmost column is the temperature value stored approximately 17 hours ago (1 dot = 1 hour). The vertical axis of the graph represents the relative change from one hour to the next.

• When the relative change from one hour to the next exceeds +10.0ºC (+18.0ºF), the dot at the highest point for the applicable hour flashes.

• When the relative change from one hour to the next exceeds –10.0ºC (–18.0ºF), there is no dot in the applicable hour's column.

• If a measurement error occurs for some reason, only a single the dot in the center column will be displayed.
