Vintage Rolex Daytona Reference 6240

By Paul Altieri, 

The Rolex Daytona reference 6240 is one of the rarest and most desired Rolex chronographs. The Daytona reference 6240 was the first Rolex chronograph to feature "screw-down" chronograph pushers. These pushers were designed to lock the two pushers in place, increasing water resistance and allowing these Daytonas to later gain the moniker "Oyster" on the dial signaling enhanced water resistance. Daytona reference 6240 examples also frequently did not say "Oyster" on the dial and instead shared dials that were the same as the Rolex 6239. Daytona reference 6240 examples had early Mark 0 or Mark 1 pushers that featured wider and more aggressive looking screw-down pushers. They are highly prized by collectors, and many were changed to later Mark 2 and Mark 3 pushers during service. The present watch features a "floating" Daytona, meaning the word "Daytona" is separated by some space below "Cosmograph". These dials are prized by collectors of vintage Rolex Daytonas. This watch features a manual-winding Valjoux chronograph movement that was regulated by Rolex.

    I have made several purchases and one sales through Bob’s. The order process, payment, processing, and most importantly delivery have all been absolutely flawless. Very quick and efficient. I never look anywhere else for used Rolex.

    Superb site and transaction, phenominal delivery time. Some slight confusion concerning the special discount at the time. I didn't receive it. No big deal I would not hesitate to purchase another rolex from Bob's ! ***
