Casio G-Shock Earth Tone Analog Digital Quartz Diver's GA-2110ET-2A GA2110ET-2 200M Men's Watch The Earth Tone timepiece combines the toughness that made G-SHOCK a standard. It bridges the gap between urban and outdoor, between every day and extraordinary. It goes with a wide range of different fashions for its slim case and double- moulded octagonal bezel and the gray tone, with the case following the shape of the bezel at all the hard turns.
