Rolex Oyster Perpetual 5011

The Rolex Oyster Perpetual 5011 is a notable “Bubbleback” reference from the mid-to-late 1940s, distinguished by its unique case designs. Produced around 1946, its significance lies in variations featuring “hooded lugs” or a “monoblocco” case, showcasing Rolex’s design experimentation. It was offered in stainless steel and 18k yellow gold. The 32mm case houses a Rolex 9 3/4 ligne automatic movement (likely Cal. A.260). The lug width is typically 17mm, and the lug-to-lug distance is estimated at 39mm. The unique case architecture makes it a particularly interesting model for vintage Rolex collectors.
