The G-SHOCK X Transformers Optimus Prime is a collaboration between Casio Japan and toy company Takara Tomy. It consists of a collectable Optimus Prime figure which stows a color-matching G-SHOCK 6900 watch within its chest cavity. The figure transforms into a pedestal for the watch to remove it, which can be replaced with Optimus’ Matrix of Leadership – known as the Chrono Matrix for this figure.
This set is a Japanese-exclusive release, and is retailing for approximately 250 USD.
