The 40th anniversary Adventurer’s Stone shock-resistant models are inspired by the stones known to adventurers as useful compasses since the Middle Ages. The G-SHOCK brand concept of continuous innovation inspires people to take on new challenges, and the design of this line is based on the value that these stones have always had to people seeking adventure. The GM-S110 is the base for this purple calcite-inspired model. After an initial overall ion plating in purple, the sides are masked at 2 and 7 o’clock and the bezel is ion plated in grey, recreating the distinctive gorgeous purple of this form of calcite.
