Casio has equipped the G-Shock Move with GPS functionality which aids in its data and tracking functions. It boasts an optical sensor that can measure heart rate by detecting the blood flow under the skin. In essence, this is truly is a G-Shock, and one you are probably familiar with in many ways. Think the Mudmaster and you will have some sense of the sheer size and overall capability of the watch itself. But like I said, it all comes down to the heart-rate monitor, which gives the watch the ability to use the new sensor technology in a whole host of ways. This watch now has everything under the sun, including solar-powered charging, which is able to take place even in low-light scenarios. To top it off, all of this functionality can be monitored through a new G-Shock Move app, set to be released by Casio on April 17.
