Casio G-SHOCK GA-110 Series – Model GA110GB-1A
The GA110GB-1A brings striking luxury to G-SHOCK’s rugged DNA, blending glossy black with bold gold for an unforgettable look. Using the iconic GA-110 as its base, this watch combines high-impact design with the legendary toughness that defines G-SHOCK.
