The Rolex Oyster Perpetual, a name synonymous with luxury and reliability, boasts a rich history stretching back nearly a century. While many associate the name with the later, more embellished Datejust and Submariner models, understanding the evolution of the Oyster Perpetual requires a journey back to its foundational years. The reference 17720, though not explicitly detailed in official Rolex archives with the same level of specificity as later models, represents a crucial link in this lineage, a significant step towards the brand’s mastery of waterproof watchmaking. While pinpointing the exact specifications and production run of a reference 17720 proves challenging due to the limited documentation available for early Oyster Perpetual models, its significance lies in its place within the broader narrative of Rolex's waterproof watch development.
This article will explore the historical context surrounding the Rolex Oyster Perpetual 17720, emphasizing its contribution to the evolution of waterproof watch technology. We will also delve into the broader market of vintage Rolex Oyster Perpetual models, addressing related searches such as Rolex Oyster Perpetual 1970 price, Rolex Oyster Perpetual 1970 value, 1970 Rolex Oyster Perpetual Date, 70s Rolex Oyster Perpetual Date, older Rolex Oyster Perpetual Datejust, vintage Rolex Oyster Perpetual value, Rolex Oyster Perpetual Datejust 1970, and Rolex Oyster Perpetual Date vintage to provide a comprehensive understanding of this iconic timepiece and its place within the collector’s market.
The Genesis of Waterproofing: A Leap Forward
The Rolex Oyster Perpetual 17720, with its screw-down crown and case back secured by rubber gaskets, marked a pivotal moment in horological history. This design, while possibly not the absolute *first* waterproof watch ever created (the claim is often debated among watch historians), represented a significant leap forward in terms of reliability and practicality. Prior to this development, watches were highly susceptible to water damage, limiting their functionality and longevity. The implementation of the screw-down crown and case back, along with the crucial addition of rubber gaskets, effectively sealed the watch movement from the elements, providing a level of water resistance previously unattainable. This innovation was a game-changer, transforming the watch from a delicate instrument to a robust and reliable tool capable of withstanding the rigors of daily wear.
While the exact specifications of the reference 17720 remain elusive, it's safe to assume it shared several key characteristics with other Oyster Perpetual models of its era. These would include a relatively simple design, often featuring a plain dial with applied hour markers and hands, reflecting the functional and utilitarian approach prevalent in early watchmaking. The movement itself would likely be a robust and reliable calibre, representative of Rolex's commitment to precision and durability even in its early days. The case material would have likely been stainless steel, a practical and durable choice for a watch intended for everyday use.
Five Years Later: Refinement and Evolution
The success of the Oyster Perpetual 17720 and its waterproof design paved the way for further advancements. Five years later, Rolex further refined its waterproof technology, building upon the foundation laid by the reference 17720. This continued innovation eventually led to the development of more advanced models, including those incorporating features like date displays and increased water resistance, expanding the functionality and appeal of the Oyster Perpetual line.
