Rolex Oyster Perpetual 6618

The Rolex Oyster Perpetual ref. 6618 is a vintage ladies’ automatic model produced throughout the 1960s and early 1970s. Housed in a 26mm stainless steel case, this reference was among the first compact Rolex watches to consistently feature an automatic movement, aligning with the brand’s growing emphasis on self-winding technology. It is powered by the Rolex Caliber 1160 or 1161, both reliable manually wound movements from the era, though some later iterations included the automatic Caliber 1165. The watch typically features a smooth or occasionally engine-turned bezel, an acrylic crystal, and simple dial configurations in silver, champagne, or black with baton hour markers and pencil hands. With a lug width of 13mm and lug-to-lug length around 33mm, the 6618 maintains excellent proportions for daily wear while retaining Rolex’s hallmark Oyster toughness, including a screw-down crown and caseback for water resistance. Paired most often with folded Oyster bracelets, the 6618 has become a sought-after choice among collectors and vintage enthusiasts seeking a durable, compact Rolex with mechanical authenticity and classic mid-century styling.
