Rolex Oyster Perpetual 6566

The Rolex Oyster Perpetual ref. 6566 is a vintage automatic wristwatch produced in the mid-to-late 1950s, known for its classic proportions and understated styling. This reference features a 34mm stainless steel case, often accompanied by a smooth or fluted bezel in stainless steel or 18k gold, depending on the specific variant. Inside is the Rolex Caliber 1030, a pioneering automatic movement offering bi-directional winding, approximately 42 hours of power reserve, and superior timekeeping reliability for its time. Dial designs were simple yet refined, typically silver or champagne-toned, with applied baton or arrowhead markers, dauphine hands, and a clean outer minute track beneath a domed acrylic crystal. A screw-down crown and caseback ensured water resistance in line with Rolex’s Oyster standards. The watch measures approximately 42mm lug-to-lug with a 19mm lug width, allowing it to wear comfortably on a range of wrist sizes. Often paired with a riveted Oyster bracelet or leather strap, the 6566 reflects the brand’s post-war push to bring precise, durable, and stylish timepieces to the global market. Today, the 6566 remains a favored choice among vintage collectors who appreciate its movement, timeless aesthetic, and historical role in Rolex’s automatic evolution.
