G-Shock Digital Bluetooth Fitness Watch G Squad Series GBD100-2D

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.
Distance measurements used in combination with the stopwatch let you keep track of your running pace, and also enable use of an Auto Lap feature that automatically keeps track of times over a specific distance.
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), and calories burned measurement, all of which provide plenty of support for your daily training. Also, new phone apps are now available to help you configure watch settings more easily and manage your workouts. In addition to Life Log and Activity History apps, you can automatically create a training plan based on targets specified by you.
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.
