A classic 1950's steel, 32 mm Rolex Oyster Royal manual and wristwatch. This model features a distinctive scooped bezel and is fitted with Rolex?s 'Super Oyster' crown. Introduced for a short period of time from c. 1951-1953, the super oyster crown was developed as an alternative water-resistant crown to the traditional screw-down crown that Rolex had first launched in 1926. Super oyster crowns were used for only a very short period of time in the early 1950s with production quickly reverting back to the screw-down oyster in c. 1953. Many of the super oyster crowns were replaced with screw-down crowns during later servicing and original examples are becoming increasingly scarce. The super oyster crown acts in the same way as a standard crown and can be wound in the resting position. .
