Year It First Dropped: 1997

There could be an entire list of GShock collaborations with streetwear brands alone, but this one pioneered them all. In an era before everyone was collaborating with everyone, Stussy continued to pave the way with this exclusive DW-6900 watch done with Casio Japan. It's been revisited a few times since its inital (and very, very limited) launch in 1997, but the original remains not only a collector's item, but also signified the beginning of a new era for streetwear.
