Casio GShock MT-G Smart Phone BT Solar World Time Model MTGB1000-1A

The new shock resistant structure of these models is the result of the G-SHOCK MT-G constant pursuit of improved strength and durability. A New 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. A Bluetooth® communication function makes it possible to connect with a smartphone running the G-SHOCK Connected* app and obtain accurate time information from an on-line time server
