These are the latest additions to the G-SQUAD lineup of sports watches from G-SHOCK, now with Bluetooth® capabilities that allow continuous connection with a smartphone.
These watches can link with the GPS of a smartphone for quicker calibration of distance measurements, enabling more accurate running distance measurements, even during use without a phone connection.

The displays of these watches use a high-definition MIP LCD, while Super Illuminator face illumination keeps face information easy to read, even in the dark. The soft urethane band material provides improved comfort, while a large number of band holes let you adjust the fit to your particular wrist.

From daily health management to improved running endurance, these new G-SQUAD models provide tools that support a wide range of fitness needs.
