Rolex Oyster 3359

A manually-wound model from the late 1930s/early 1940s, this reference is significant for its association with both the “Oyster Army” and “Observatory” names. It represents Rolex’s dual marketing strategy of targeting military personnel with a durable watch while simultaneously promoting its chronometric precision. This fusion of ruggedness and certified accuracy in a single product was fundamental to building the brand’s reputation for creating high-quality, reliable instruments during the WWII era.
