John Mayer is an American singer, songwriter, guitarist, Grammy-winner, and all-around musical legend that requires no introduction anywhere he goes. But in addition to his many musical accomplishments, he’s also a renowned watch collector, writer, and designer that’s partnered with Hodinkee on more than one occasion. Following up on the smashing success of the John Mayer-designed Casio G-Shock Ref. 6900 Watch is another Hodinkee collaboration. This time it’s the Casio G-SHOCK Ref. 6900-PT80 you see here. This limited-edition timepiece takes its design cues from the original Casio PT-80 keyboard and features the legendary “Triple Graph” display with red/green/gray registers, an off-white resin case and strap, and plenty of bright pops of color throughout. As if the understated yet stunning exterior wasn’t enough, it includes a caseback engraved with all the parties involved so you’ll never forget what kind of pedigree you’re wearing on your wrist–even if it’s an incredibly affordable watch.
