GM-2100MWG-1A
Travel the Milky Way with a very special metal-covered G-SHOCK.
This limited edition starts with the GM-2100 and recreates its iconic octagonal bezel in purple ion-plated metal with a laser-printed galaxy motif. The dial features a gradation of color in a vapor deposition finish, evoking the Milky Way shining in the night sky. The band echoes the night sky image, its depth captured with a matte translucent band in navy blue resin. The case back is ion plated in black and laser engraved with a design inspired by the Milky Way.
All these details come together in a gorgeous design that brings the awe of the cosmos to your wrist in stylish purple, black, and navy — just right to complement an array of different occasions.
