G-SHOCK has collaborated with the maker’s of Rubik’s Cube for a limited edition. Based on the octagonal GA-2100, and Rubik’s Bauhaus borrowed color scheme the watch can change its appearance as easily as the famously frustrating puzzle, using an interchangeable bezel and tool. The watch offers the choice of white or black bezels against its black strap, green keeper and orange pin buckle, while the geometry of the cube features on the watch’s analogue/digital dial.

Even with the interchangeable elements, the GAE-2100RC-1AER still features G-SHOCK’s carbon core guard architecture to offer the same level of shock resistance and 200m water resistance as other GA-2100 references. The GAE-2100RC-1AER drops on February 9 via G-SHOCK online.

Invented in 1974 by Ernő Rubik, the Rubik's Cube® has become one of the best-selling toys in history, with over 450 million cubes sold. Casio commented on the collaboration as follows: "There are many synergies between G-SHOCK's approach to building watches and Rubik's iconic cube. A robust, eye-catching exterior with a deeper complexity and a shared 'Never Give Up' philosophy make this a very natural partnership."
