Casio Releases New G-SHOCK with Two Sensors for measuring atmospheric pressure/altitude and temperature

Casio announced today the release of a new shock-resistant watch in its G-SHOCK lineup—the GDF-100, equipped with two sensors for measuring atmospheric pressure/altitude and temperature. The new Casio GDF-100 is equipped with two types of sensors, one for pressure and the other for temperature, making it highly practical and functional for use in the great outdoors. High-brightness LEDs have been used for the display backlighting, providing greater display readability in dark locations. The pressure sensor, installed in the case at the 9 o’clock position and designed to take in ambient air from the front of the watch face, automatically measures atmospheric pressure every two hours. In addition to displaying atmospheric pressure numerically, the new Casio GDF-100 shows pressure changes since the previous reading in plus and minus increments of five in a circular indicator at the 2 o’clock position. Accordingly, the user can forecast improvements in the weather based on a positive pressure change, or a deterioration based on a negative pressure change.

The Casio GDF-100 also measures altitude up to 10,000 meters, using atmospheric pressure conversion. The altitude is shown every five seconds for the first three minutes after the start of altitude measurement, and is shown every two minutes after that, making the watch very useful for mountain climbing and rock climbing. Data obtained through the temperature sensor are displayed simultaneously with either the atmospheric pressure or altitude. This allows the user to confirm the current environmental conditions. With other features such as a world time function that displays the current time in 48 cities, the GDF-100 offers rich functionality in addition to its tough performance.
