Along with the full size metal-covered GM-2100 series, G-Shock is also releasing the smaller GM-S2100 series in August. The three launch models for this mini “CasiOak” line include the silver and green GM-S2100-3AJF (24,200 yen tax-included), gray and black GM-S2100B-8AJF (26,400 yen), and rose gold and black GM-S2100PG-1A4JF (26,400 yen). The GM-S2100-3A, GM-S2100B-8A, and GM-S2100PG-1A4 are also expected to be released worldwide after the Japan release. G-Shock U.S. is expected to release the GMS2100-3A ($180), GMS2100B-8A ($200), and GMS2100PG1A4 ($200).
The GM-S2100 measures 45.9 x 40.4 x 11 and weighs approximately 55 grams. The functions are the same as the GM-2100. Unlike the GM-2100 and the full resin GMA-S2100, the GM-S2100 does not have an analog day of the week indicator, but it has a new module, and the day of the week (or date or time) can be displayed on the LCD display along with the seconds.
The S Series is a women’s G-Shock line featuring the full shock resistance and 200-meter water resistance of their larger counterparts. These GM-S2100 models have a unisex style that are suitable for anyone who prefers a smaller watch, although the larger GM-2100 is considered mid-sized and not a very large G-Shock.
