Travel to past futures inspired by a G-SHOCK science fiction world where steam power still rules. To give the GM-110 metal-clad large case of the look and feel of worn brass, the GM-110VB bezel is treated with aged IP in black, while the GM-110VG is finished with aged IP in gold. Hour and minute hands shaped like machinery gears add a mechanical touch to the rugged design. Cool designs to accessorize roguish, casual styles.
