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^ to 60.0^ (or 14.0^ 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 bottom of the hour readings are shown in the graph.
Temperature tendency graph contents are updated every 30 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.

(part you cannot see) Moon phase (part you can see)
| Moon Phase Indicator | ||||||||
| Moon Age | 0.0 - 1.827.7 - 29.5 | 1.9 - 5.5 | 5.6 - 9.2 | 9.3 - 12.9 | 13.0 - 16.7-20.2 | 20.3 - 23.9 | 24.0 - 27.6 | |
| Moon Phase | New Moon | First Quarter (Waxing) | Full Moon | Last Quarter (Waning) |
•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.

•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 seconds count of the World Time is synchronized with the seconds 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 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.
