• Casio Tough Solar Powered technology charges the watch by light. With this eco-friendly feature, you never need to replace the battery, also helping maintain the water resistancy of the watch.
• Tough Movement - a CASIO-original super-thin analogue movement made possible by hybrid mounting protects against damage and enables auto home position correction that helps keep you on time all the time.
• MULTIBAND 6 Radio Controlled allows reception of time calibration signals from one of six transmitters around the globe : Germany, The United Kingdom, The United States, China, and Japan (two transmitters).
• Barometer (260 / 1.100 hPa) sensor measures the air pressure (measuring range: 260/1100 hPa) and presents this on the display in the form of a symbol. This enables early detection of weather trends.
• An audible alarm will sound if there is a sudden change in barometric pressure is sensed by the watch, the blue bezel marked over/under 1-10 will display the severity.

• A pressure sensor detects changes in the air pressure and converts the result into an altitude up to 10,000 m.
• A thermometer sensor measures the ambient temperature around the watch and displays it in °C (-10°C /+60°C).
• 10,000m altimeter pressure sensor detects changes in the air pressure and converts the result into an altitude up to 10,000 m.
• Chronograph function accurate to 1/100 sec. - 24 hours measures elapsed time, split time and final time are measured with 1/100-sec accuracy. The watch can measure times of up to 24 hours.
