Rolex Oyster 3139

Often marketed as the “Oyster Viceroy,” this manually-wound reference from the early 1940s is significant for representing Rolex’s focus on combining durability with certified precision. Housed in a distinctive flared case, the Viceroy line aimed to prove that a robust Oyster watch could also be a highly accurate chronometer. This strategy was key in elevating the brand’s status beyond simple durability, establishing the foundation for its post-war reputation as a premier maker of luxury chronometers.
