Plunge into cool-blue waters under the blaze of the mid-summer sun with the hallmark toughness of an oasis-inspired G-SHOCK. The slim, octagonal GA-2100 with a base color of desert sand beige. Then inspired by the refreshing sanctuary of an oasis lake, touches of blue-green accent the dial. Summery seasonal colors evoke the thrill of an oasis suddenly emerging in a tropical landscape. A great casual accessory for your marine sports style or street-savviest fashion.
