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.
- 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. To 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 Tendency 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 the bottom of the hour readings are shown in the graph.
- Temperature tendency graph contents are updated every 30 minutes.
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 +10.0°C (+18.0°F), the dot at the highest point for the applicable hour flashes.
- When the relative change from one hour to the next exceeds –10.0°C (–18.0°F), 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.
Recalling Temperature Data
- The measurements the watch takes at the top and the bottom of each hour are stored in memory automatically. Memory can hold up to 50 measurement records. You can use the Temperature Data Recall Mode to recall memory data when you need it.
- Each temperature data record has a number. The newest data record is number 01, while the oldest data record is the one with the highest number.
- When there are already 50 records in memory, storage of a new temperature reading causes the oldest record (record number 50) to be deleted automatically to make room for the new data. The new data is assigned record number 1, and all of the numbers of all the other records (01 to 49) are incremented by 1 (becoming 02 through 50).
To recall temperature records
- In the Timekeeping Mode, press C twice to enter the Temperature Data Recall Mode.
- This displays the newest record currently in memory.
- Use D (+) to scroll through the records.

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 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. The greater the angular distance between the Moon and the Sun,* the more we see illuminated.
- The angle to the Moon in relation to the direction at which the Sun is visible from the Earth.
- This watch performs a rough calculation of the current Moon age starting from day 0 of the moon age cycle. Since this watch performs calculations using integer values only (no fractions), the margin for error of the displayed Moon age is ± 1 day.
Thermometer
Temperature Sensor Calibration
The temperature sensor built into the watch is calibrated at the factory and
normally requires no further adjustment. If you notice serious errors in the
temperature readings produced by the watch, you can calibrate the sensor to
correct the errors.
Important!
Incorrectly calibrating the temperature sensor can result in incorrect
readings. Carefully read the following before doing anything.
- Compare the readings produced by the watch with those of another reliable and accurate thermometer.
- If adjustment is required, remove the watch from your wrist and wait for 20 or 30 minutes to give the temperature of the watch time to stabilize.
To calibrate the temperature sensor
- In the Timekeeping Mode, hold down A until the seconds start to flash, which indicates the setting screen.
- Press C nine times to display the temperature sensor calibration screen.
- Use D (+) and B (–) to change the calibration value.
- You can change the value in 0.1°C (0.2°F) steps, in a range of ±10°C (±18°F). The calibration value shows ‘‘–.-’’ when the setting is outside the allowable range.
- To return the calibration value to its default (no calibration, indicated by ‘‘- -’’), press D and B at the same time.
- Temperature sensor calibration will not be possible if the current reading is outside the allowable display range (–10.0°C/14.0°F to 60.0°C/140.0°F) and the calibration value shows ‘‘- -’’.
- Setting a sensor calibration value does not affect temperature values that are already stored in memory.
- After configuring the setting you want, press A twice to exit the setting screen.
To specify the temperature display unit
- In the Timekeeping Mode, hold down A until the seconds start to flash, which indicates the setting screen.
- Press C 10 times to display the temperature unit setting screen.
- Use D to switch between Celsius ( OC ) and Fahrenheit ( OF ).
- The initial factory default and the initial default after battery replacement is Celsius ( OC ).
- After configuring the setting you want, press A twice to exit the setting screen.
- The temperature display unit setting you select is also applied to temperature values that are already stored in memory.
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 Countdown 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 (mute indicator not displayed) and off (mute indicator displayed).
- Since the C button is also the mode change button, holding it down to turn the button operation tone on or off also causes the watch’s current mode to change.
- The mute indicator is displayed in all modes when the button operation tone is turned off
Auto Return Feature
- If you leave a screen with flashing digits on the display without performing any operation for two or three minutes, the watch saves any settings you have made up to that point and exits the setting screen automatically.
- The watch will change to the Timekeeping Mode automatically if you do not perform any operation in the Fishing Mode, Temperature Data Recall Mode, Alarm Mode, or Hand Setting Mode for two or three minutes.
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.
- With the 12-hour format, the P (PM) indicator appears on the display for times in the range of noon to 11:59 p.m. and the A (AM) indicator appears for times in the range of midnight to 11:59 a.m.
- With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without any indicator.
- 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 batteries replaced.
World Time
- The second count of the World Time is synchronized with the second’s count of the Timekeeping Mode.
- All World Time Mode times are calculated from the current time in the Timekeeping Mode using UTC time differential values.
Illumination Precautions
- The electro-luminescent panel that provides illumination loses power after very long use.
- Illumination may be hard to see when viewed under direct sunlight.
- The watch may emit an audible sound whenever the display is illuminated. This is due to the vibration of the EL panel used for illumination and does not indicate malfunction.
- Illumination turns off automatically whenever an alarm sounds.
- Frequent use of illumination runs down the batteries.
