We all knew that John Mayer could make the ladies swoon with his sexy blues guitar and sultry vocals, but a watch collector? With a emphasis in Vintage Rolex’s? There seems to be nothing this man can’t do. In a new series of watch-focused blog posts, Mayer outlines the five best Vintage Rolex’s that $8000 can buy, including classics like the Submariner and Explorer II. It’s obvious that this guy knows exactly what he’s talking about, all the way down to comparing the movements on the GMT Master and Explorer II. Keep your eye from more timepiece advice from Mayer, as it’s certainly bound to be exceptional.
