This is a seriously unique collaboration between G-shock and the artist Stash. It is the only G-shock I know of which has a faux spray can as it's OEM watch box. It is also a very attractive design by Stash in his own famous style. If you like blue and black you will like this watch. It also has a stainless buckle and keeper which is unusual for a GA100. I don't know how "limited" it is but I like it so much I have two, one to wear and one for later. Prices for this model are dropping at the moment, get em while you can! (See what I did there?)
