John Mayer teamed with Casio and the website Hodinkee to create the G-SHOCK Ref 6900 by John Mayer, which costs under $200. The design of the limited-edition timepiece was inspired by the electronic sampling keyboard that John played as a kid back in the day: the Casiotone SK-5.
Unfortunately, it just sold out, despite the fact that it was released only yesterday.
And there's no word on whether or not more of the watches will be created.
