Casio Baby-G BGS-100 Series

One of the first Baby-G running models with a pedometer sensor. The three-axis sensor is able not only to count the number of steps taken during training, but also eliminates false sweeps with your hands, and also emits a sound signal for prolonged inactivity [provided that you have not yet completed the daily goal of the steps]. Bright colors of the BGS-100 will come in handy for sports shoes and clothing, and the small dimensions of the case will definitely not interfere with the movements of the wrist during races and other activities. Right on the watch screen displays the history of the steps taken in the form of graphs – weekly, daily and hourly. The stopwatch has a solid capacity – up to 24 hours with an accuracy of 1/100 of a second. Of the basic functions, one can also distinguish a timer, world clock, alarm clock and backlight.

Enjoy our Baby-G BGS-100 Watch Review

The case size, to put it mildly, surprised, I have never seen such a small watch. It’s about 45.2×42.6 x 13.3mm. Honestly, when you study the characteristics at the office. site or you look stock photos, specific figures speak little about. You need to see and feel. This watch is not just small, the BGS-100 can even be called miniature. I tried to put them on my hand, but as you guessed, nothing came of it. I had to try on my wife’s hand [she herself has a BGA-190 and BGA-160, so there is something to compare with]. Perfect for both women and children’s wrists. Read Full Review →
