The Rolex Oyster Perpetual Submariner Date Men's 39, while no longer in current production, remains a highly sought-after timepiece among collectors and enthusiasts. This iconic dive watch represents a crucial chapter in Rolex's history, bridging the gap between the classic Submariner and the modern, larger iterations. Understanding its significance requires delving into its design, functionality, history, and its place within the broader Rolex Submariner lineage. This article will explore all these aspects, offering a comprehensive overview of the 39mm Submariner Date and its enduring appeal.
An Underwater Tool of Precision and Elegance:
The Submariner's reputation as a quintessential dive watch is deeply rooted in its robust construction and practical functionality. The 39mm model, though smaller than its successors, retains all the essential elements that define a Submariner. Its most distinctive feature, and a key to its functionality as a diving instrument, is the unidirectional rotatable bezel. This bezel, with its 60-minute graduations, allows the diver to precisely monitor their elapsed dive time, a crucial safety measure for managing decompression stops and preventing decompression sickness ("the bends"). The precise clicks of the bezel ensure accurate timekeeping, even in challenging underwater conditions.
The bezel insert on the Rolex Oyster Perpetual Submariner Date 39, typically made from a hard, corrosion-resistant ceramic known as Cerachrom, is virtually scratch-proof. This material ensures the long-term legibility of the graduations, maintaining the watch's accuracy and reliability even after years of use, both in and out of the water. The superior durability of the Cerachrom bezel is a significant improvement over earlier aluminum bezels, reflecting Rolex's ongoing commitment to innovation and material science. This attention to detail speaks volumes about the watch's intended purpose – to be a dependable and precise instrument in the most demanding environments.
Beyond the bezel, the Oyster case itself is a testament to Rolex's engineering prowess. The robust construction, with its Triplock winding crown and screw-down caseback, provides exceptional water resistance, typically rated to 300 meters (1,000 feet). This ensures the watch's internal components are protected from water ingress, crucial for maintaining its accuracy and longevity under pressure. The case's design, refined over decades, is both functional and aesthetically pleasing, showcasing the perfect blend of form and function that characterizes Rolex's approach to watchmaking.
The Heart of the Submariner: Caliber 3135
The Rolex Oyster Perpetual Submariner Date 39 typically houses the Caliber 3135, a self-winding mechanical movement renowned for its accuracy, reliability, and robustness. This movement, entirely manufactured in-house by Rolex, is a testament to the brand's commitment to vertical integration and its mastery of watchmaking techniques. The Caliber 3135 boasts a power reserve of approximately 48 hours, ensuring the watch continues to function even if it's not worn for a period of time. Its robust construction, with its paramagnetic blue Parachrom hairspring, makes it highly resistant to shocks and magnetic fields, further enhancing its reliability in challenging conditions. The movement's precision and accuracy are hallmarks of Rolex's commitment to quality and performance. Regular servicing by an authorized Rolex service center is key to maintaining the Caliber 3135's optimal performance and longevity.
