This is vintage 1958 Rolex Oyster Perpetual ref. 6552 with a pristinely restored black dial having restored Dauphine hands and white, arrow-tipped sweep seconds. This second hand was likely replaced at some time, but really does work well with the dial. The 34mm stainless steel case really does look very clean on the wrist. The caliber 1030 Rolex automatic movement was recently cleaned and is accurately maintaining time. You will enjoy the bold, deep-black dial!
