– Tough Solar (CASIO’s original solar-charging system converts not only sunlight but also light from fluorescent lamps and other sources into power)
– Carbon Core Guard structure (integrates the lugs and pipes that connect the band into single pieces, creating a wall that isolates the watch’s module from impact. The resin of the center case is also reinforced with carbon fibers, which further enhances module protection, while reducing overall weight)
– G-SHOCK Connected App (you may manage all watch settings through your phone)
– Mobile link (Wireless linking using Bluetooth(R)) (for time sync with your phone data)
– Digital compass (measures and displays direction as one of 16 points)

– Thermometer (can measure and display the outside temperature in a range from -10 C to 60 C)
– Barometer (measures the air pressures and displays tendencies in the weather)
– Altimeter (The electronic mechanism “estimates” the altitude based on the air pressure)
