Since its launch in 1983, the Toughness watch continues to evolve in pursuit of strength and endurance, the GM-110 series is based on the combination model GA-110 with digital and analog displays. The GM-110 is finished with a metallic texture, and the dial features a distinctive Y-shaped part with a digital display and hour and minute hands balanced for improved visibility. The popular model has evolved into the new G-SHOCK standard.
