G-Shock Men's Silver Stainless Steel Bracelet Watch, GMB2100D-1A

Elegance expressed in forged steel beating with the heart of G-SHOCK’s water and shock resistance: that’s the GMB2100D-1A. The silver full-metal construction undergirds an array of performance tech and radiates sophistication. The polished metal offsets the vapor deposition finish of the black dial, demanding equal attention between the metal bezel and the detail of the dark watch face. The full-metal GMB2100D-1A is a powerhouse of performance, style, and durability.
