Set includes: main body, box, instruction manual, warranty card included in the instruction manual Water resistance specification: 20 ATM water resistance function World Time GMT/UTC Alarm LED light Details: This is G-SQUAD, the sports line of G-SHOCK that pursues insatiable toughness. The G-SQUAD has a square form inherited from the first generation G-SHOCK, and is equipped with functions that are useful for training such as running, such as an acceleration sensor, distance measurement function, and smartphone linkage function. By linking with the GPS function of a smartphone, the distance measured by the acceleration sensor can be corrected. Once the distance is corrected, it can be measured more accurately by the watch itself next time. In addition, it is possible to measure the running pace and the auto-lap function that automatically measures the time every time you run a certain distance. In addition, by connecting the watch to the dedicated "G-Shock Move" application, which is useful for managing various watch settings and training, you can check your life log and activity history, and automatically create a training plan that matches your set goals. It also automatically creates training plans that match the goals you set, supporting your daily training. The display is made of high-definition MIP LCD, and when the front button is pressed, the Super Illuminator light comes on for visibility in dark places, giving the watch a G-SHOCK-like gadget feel. The band is made of soft urethane material to enhance the fit and has a large number of holes to allow for fine fitting adjustments. The watch is also equipped with a Bluetooth® connection for automatic time correction and notification functions*, making it a useful addition to your lifestyle. This G-Shock is useful for a wide range of purposes, from daily health management to enhancing endurance in running. The G-Shock's vibration function alerts the user to elapsed time and calories burned during training, as well as notifications of incoming calls, e-mails, and SNS from smartphones connected via Bluetooth®.
