Rolex. A Fine Stainless Steel Chronograph Wristwatch with Bracelet

A true Oyster case is defined by the screw-down case back, screw down crown and screw down chronograph pushers, thus ensuring increased water resistance. Reference 6265 is indeed one of these highly sought-after models. Together with its sister reference 6263 (the difference being the black-insert bezel rather than the metal one), the reference 6265 is the final evolution of manually wound Daytonas. It is defined, beyond its metal insert and screw-down pushers, by the caliber 727 (evolved from caliber 722-1).
