Casio’s flagship timepiece collection proudly announces the newest edition to the G-Shock family, the GDF100.

A brand new case design for G-Shock, the GDF100 has a front-facing pressure and temperature sensor built into the case/bezel at the 9 o’clock position. The pressure sensor measures barometric pressure as well as converts barometric pressure readings into relative altitude readings based on International Standard Atmosphere conversion values stored in the watch’s memory.
For greater visibility and performance during the critical stages of climbing or descent, both temperature and altitude can be viewed on the watch display simultaneously.

Additional GDF100B features includes G-Shock’s legendary shock resistant structure, 200M Water Resistant, Super Illuminator LED Backlight, World Time (31TZ/48 City), 5 Independent Daily Alarms, Hourly Time Signal, 1/100th Sec. Stopwatch, Countdown Timer, 12/24 Hr. Formats and Mute Function.
