Year It First Dropped: 2013

For fans of collectible toys and watches, this collaboration is a dream come true. G-Shock teamed up with Medicom Toy for this awesome timepiece. Of course it can't be a true Medicom Toy collaboration without its trademarked Bearbrick, and it came in the form of a large Bearbrick head as part of the packaging. Die-hard collectors of G-Shock were probably fighting with Bearbrick buffs to get their hands on the complete packaging. That combination alone made these tough to get a hold of.
