The HODINKEE John Mayer Casio G-SHOCK 6900 released in December 2020 at a $180 USD Retail Price. The Casio G-Shock DW6900JM20-8CR was a surprise collab between luxury watch blog Hodinkee and seven-time Grammy Award-winning artist John Mayer. Utilizing the classic G-Shock silhouette DW6900 as a backdrop, Mayer then added his own touches with a slate gray case and strap along with a teal "G-SHOCK" and neon yellow lettering. Mayer was inspired by the Casiotone SK-5 keyboard he owned growing up. Featuring signature shock resistance, the G-Shock DW6900JM20-8CR is as tough as it is nostalgic.
