The gbd200s are the latest additions to the g-shock move lineup of sports watches, 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. Other standard features include a step tracker (pedometer), interval timers (up to 20 sets of five timers each), lap time measurement (up to 140 records for up to 100 runs), all of which provide plenty of support for your daily training. 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.
