Casio G-Steel GM-5600RW-1 Black Bio-Based Resin Band Men Sports Watch

Another brick in the wall — this one in a full rainbow of color. Introducing bold designs with watch glass or dial featuring the original brick wall pattern of the very first G-SHOCK in full-on color. 

Rainbow vapor deposition reproduces the symbolic brick wall imagery in brilliant rainbow hues that shift and change depending on the light. The colorful design stays true to the origin of G-SHOCK with the spirit of toughness it takes to overcome barriers and constantly push limits. 

Choose your favorite from the iconic 5600 models or the 2100 analog-digital combination models. 

For the DW-5600 and GM-5600 models, the watch glass features the color-shifting brick pattern reproduced with vapor deposition in a rainbow-hued gradation. For the GA-2100 and GM-2100 models, the dial’s iridescent brick pattern is achieved with a combination of silver vapor deposition, laser etching, and rainbow-colored printing. 

A cool, colorful fashion accessory with a dynamic design that wows from every angle.
