An array of large metal buttons on the right provide one-touch access to compass, barometric pressure/altitude, and temperature readings that appear on the LCD.
Icons on the face glass next to each of the buttons contribute to easy –to-understand, intuitive outdoor environment.
The digital LCD uses a high-contrast bold font, which, in combination with an STN LCD, ensures improved visibility even under harsh sunlight.


Triple Sensor, Ver.3

Miniature built-in sensors take highly accurate readings of direction, atmospheric pressure/temperatures and altitudes and indicate the measurement values with an LCD. They detect changes in natural phenomena immediately to support users in making appropriate responses.

Tough Solar

This proprietary CASIO solar-powered battery-recharging system assures stable operation of various power-hungry functions, including dial lighting, alarms, stopwatches and measurement functions.

Large direct buttons

Designed for quick measurement with a single push, the buttons can be operated without taking gloves off.

Auto Light Switch

For quick, easy data confirmation, even in the dark or with both hands occupied. You need both hands for many outdoor activities, and you don't always have one free to illuminate your watch face in low-light conditions. The Auto Light Switch solves this problem by illuminating the light whenever you turn your wrist to bring the watch into the viewing position.


Display visibility has been improved by adoption of a dot matrix STN LCD panel. A hand retraction function is also installed to prevent overlapping hands from obstructing the LCD in the Timekeeping mode by temporarily retracting the hands from above the LCD.

Sunrise, sunset time display

Knowing the time remaining before sunset helps you to schedule climbs to assure a safe descent, or to determine the appropriate time to wake up or pitch a tent.

Atmospheric pressure tendency alarm

An atmospheric pressure tendency alarm has been installed to alert wearers to any notable change.
