A ref. 6262 Daytona, a transitional Daytona in production for one year. The 6262 introduced the Valjoux 727, a higher-strung 21600 vph calibre, but looks nearly identical to the inaugural ref. 6239 Daytona. For those who study Daytonas, the 6262 is an extremely interesting and rarely seen transitional series. It represents the final chapter in all of Pre-Daytona and early Rolex chronograph evolution, handing off the baton from low-beat, pump pusher Daytona to high-beat, Oyster-only Daytona.
