Four new colorways for the GMA-S2100 “Mini CasiOak” series are launching in August. The colored bezels, bands, and band keepers have translucent properties, making the light gray carbon fiber-reinforced cases visible under the bezels. These compact watches are smaller and lighter than the standard GA-2100 at 46.2 x 42.9 x 11.2 millimeters and 46 grams each. Three of the models have a positive LCD display, and the black model has an inverted LCD. The index markers are treated with a half-matte vapor deposition, and the blue and pink models use slightly polarized paint on the dials and dial rings.
The GMA-S2100SK is fully shock-resistant and water-resistant to 200 meters. Other features include world time, 1/100-second stopwatch, 24-hour countdown timer, 5 daily alarms, full auto-calendar, hand shift function, hourly time signal, button tone on/off, and double LED light with adjustable afterglow.
