The Ga2110 models combine practical and utilitarian colors of the bezels, faces, and bands that go well with today's fashions to create distinctive looks. These new G-Shock models combine thin cases with new designs. A carbon core guard structure protects the module by enclosing it in a carbon case. The 45mm blue case is made of fine resin embedded with carbon fibers for outstanding strength, crack resistance, and durability. The blue resin strap secures with a buckle clasp and the watch is water-resistant to 200m.
