Rolex Oyster 3270

A manually-wound Oyster model from the late 1930s, housed in a “cushion” or “tonneau” shaped case. Its historical significance lies in its role as a foundational piece that helped establish the reputation of the waterproof Oyster case before the “Perpetual” automatic movement became standard. These durable and functional watches were crucial in building the brand’s identity and consumer trust in the pre-war era, emphasizing resilience and reliability.
