G-SQUAD SMARTPHONE LINK BSA-B100MT-1AJF. This is a mobile link compatible model that comfortably supports daily exercise and training. We have adopted a thin case so that it does not get in the way during exercise. It is equipped with functions that are useful for daily health management and sports, such as an automatic double LED light, a step counting function, a timer that can measure up to 5 x 20 sets, and a lap memory of up to 200. In addition, daily activity record management and exercise settings have been realized by linking with the dedicated app “BABY-G Connected” via Bluetooth communication. You can also calculate calories and set target steps. By linking with the app, we are also pursuing the original functions of the watch, such as automatic time correction. Case size (length x width x thickness) 49.6 x 41.4 x 12.6 mm. Shock-resistant structure (shock resist). 10 ATM water resistant. Battery life: about 2 years. Step reminder function (notifies you with a display and electronic sound if there is little walking within a certain period of time, with ON/OFF switch). Step count graph (displays the number of steps per hour in 6 levels for 11 hours). Step count display range: 0 to 999,999 steps. International Buyers – Please Note.
