The most distinctive specs of GMA-S2100 *Editorial
Compact size (46.2 x 42.9 x 11.2 mm, which is less than original GA-2100. Will suit perfectly on small wrists)
The first Octagon for Women (very popular style)
Good for children (boys and girls as the size fits and there is no any “Baby-G” name, that boys do not like)
Basic but useful functions (world time, 1/100-second stopwatch (24 hours), countdown timer, 5 alarms, hand shift function, etc)
Amazing colors line (color schemes aimed at women)


Other G-Shock GMA Watches *similar by price and functions but different by cases
