G-Shock G-Squad GBD-H2000 Watch
G-Shock's latest G-Squad watch makes it one of the most robust fitness trackers on the market — along with being an outstanding watch. The G-Squad GBD-H2000 packs six sensors — an accelerometer, gyroscope, an optical heart rate and blood oxygen sensor, magnetic sensor, pressure sensor, and thermo sensor — giving a data-rich picture of both the workout and the conditions it takes place in. Built-in GPS and eight different modes track activities from running to swimming, along with the Nightly Recharge feature that tracks sleep. The GBD-H2000 features a biomass plastic bezel and band with USB and solar charging.
