This proprietary CASIO solar-powered battery-recharging system assures stable operation of various power-hungry functions, including dial lighting, alarms, stopwatches and measurement functions.
The altimeter determines the altitude at your current location based on accumulated atmospheric pressure changes measured by the pressure sensor. Setting the altimeter at a location where you know the precise altitude before starting your ascent enables it to take even more precise altitude measurements.
Setting the altimeter at a location where you know the precise altitude enables you to determine the elevation of your current position with respect to sea level. If you come across a marker indicating 400 meters above sea level while hiking or climbing, for example, simply set the altimeter at 400 meters. This enables you to obtain more accurate readings with respect to sea level when you take subsequent measurements after moving on.
The altitude memory stores data on the month, date, time and results of altitude readings taken automatically at regular intervals and displays the highest and lowest altitudes measured as well as the cumulative ascent/descent altitude and relative altitude. This data provides an easily understandable summation of your ascents and descents during a climb.
Checking against contour lines on a map enables you to confirm your cumulative ascents/descents. Determining the height of your hourly ascents by resetting the altitude differential display once an hour can be helpful in establishing a reasonable climbing plan, for example.

A graphic display of atmospheric pressure readings taken at regular intervals reveals pressure trends at a glance. When the pressure is rising, the weather is likely to improve; when it's falling, there's usually worse weather ahead. This feature can remind you to take your swimming suit along, or alert you to approaching trouble.
The barometer measures the atmospheric pressure every two hours automatically and displays the recent atmospheric pressure tendency and the current pressure graphically.
If you determine magnetic north with the direction measurement function and place a map beside your watch, you can align the map with the surrounding geography.
You can change the direction measurement standard from “magnetic north” to “true north” by inputting the magnetic declination data indicated on a topographical map to correct the direction.
The Bearing Memory memorizes directions detected by the direction measurement function and displays them continuously in graphic format. You can travel straight toward your destination by following a course determined with the memorized direction displayed steadily in the 12 o’clock position on your watch face. This capability also comes in handy when visibility is low due to such factors as trees or fog.
The temperature generally decreases by approximately 6.5°C with every increase in altitude of 1,000 meters, or 3.6°F with every increase of 1,000 feet. If the temperature at 1,000 meters is 10°C, therefore, the temperature at 3,000 meters will probably be about -3°C.
