This product is no longer available for purchase.

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

Rainbow vapour deposition reproduces the symbolic brick wall imagery in brilliant rainbow hues that shift and change depending on the light. The colourful 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 favourite 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 colour-shifting brick pattern reproduced with vapour 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 vapour deposition, laser etching, and rainbow-coloured printing.

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

Vibrant presence (5600 line: DW-5600RW, GM-5600RW, GM-5600BRW)

Rainbow-hued gradation vapour deposition and black printing is employed for the brick pattern inherited from the very first G-SHOCK. Reproducing the timeless, iconic design with such innovative coloration expresses both truth to origin and constant innovation.

*Every watch in the 5600 line has a totally unique gradation of hues due to details of the special vapour deposition process applied to the glass each time (second image).

A brilliantly distinctive look (2100 line: GA-2100RW, GM-2100RW, GM-2100BRW)

The brick pattern is applied across the surface of the dial using silver vapour deposition, and then partially removed with a laser-peeling process, and rainbow hues are created with multicolour printing. An iconic design element of the very first G-SHOCK — the origin of the 2100 line — is colourfully reproduced in a highly expressive analog style.

Shock-resistant structure with metal bezel

The glass fibre-reinforced resin case is covered with a stainless-steel bezel. The intricately shaped bezel is crafted with meticulous processes of forging, cutting, and polishing, with separate hairline and mirror finishes applied to individual surfaces.

*Image shows the bezel of the GM-2100 models, made in a multi-stage process.

Attention to materials: Bio-based resin

Key resin components used in the case, band, and more are made with bio-based resin. Produced using renewable organic resources, the material is expected to help reduce environmental impact.

*Image is included for illustrative purposes only.
