Casio G-Shock Sports GBD-100SM-4A1DR

FEATURES

Introducing new colors for the G-SHOCK lineup of GBD-100 sports watches. Black and white base coloring is combined with vivid light collecting resin and semitransparent resin for a dazzling design that contributes to the enjoyment of a wide range of activities.
Function-wise, these models employ Bluetooth® technology to allow access to a smartphone's GPS for quicker calibration of distance measurements. Once calibration is done, the watch is able to perform more accurate running distance measurements, even when it is no longer connected to the phone.
Distance measurements used in combination with run time measurements let you keep track of your 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. In addition, 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. 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. These watches connect with your phone via Bluetooth® to support auto time adjustment, phone notifications, step tracking, and other functions throughout the day. Battery life is approximately two years between replacements.

These watches can link with the GPS of a smartphone for quicker calibration of distance measurements.
