Most of you probably already know that this year is G-SHOCK’s 30th anniversary and for that they have been collaborating with different brands throughout the year. One collaboration we haven’t seen yet for the 30th anniversary is the one with Mastermind Japan, which couldn’t be skipped of course. The collection consist of three models representing three decades in total. The models chosen are the DW5600, DW6900 and the G100. Keep an eye out at nearby G-SHOCK retailers for this collab.
