Today Casio, Hodinkee, and John Mayer debuted a collaborative limited edition version of the G-Shock Ref. 6900.

Inspired by the Casiotone SK-5 sampling keyboard that Mayer played growing up. “The Casiotone SK-5 was instrumental in Mayer’s musical education, and acts as the design catalyst for this timepiece,” according to the Hodinkee. First launched in 1995, the G-Shock reference 6900 is the iconic Japanese made triple-graph digital quartz watch model that helped Casio gain traction on the fashion and streetwear scene.

“When Casio approached me about the possibility of working together on a G-SHOCK, it actually timed out really well,” said Mayer. “I had already been pretty deep into wearing the ‘Mudmaster’ models, and something felt cosmically right about a G-SHOCK being the first watch collab I’ve ever done. Casio keyboards came to mind as much as the watches did. Then I remembered how important the Casiotone SK-5 was in my life, and it got exciting really fast. It’s the perfect bridge between my double life as a musician and a watch enthusiast.”

As you can see, the slate-gray body and yellow and teal highlight colors of the DW-6900, tie directly into the SK-5 aesthetic. The case measures 53.2 mm by 16.3 mm, weighs 67 grams, and is made of resin with a stainless steel caseback that’s engraved with “JOHN MAYER” and “HODINKEE.” The depth rating is 100 meters.
