The Rolex Submariner 16620. The mere mention of this reference number conjures images of rugged elegance, unparalleled reliability, and a legacy forged in the depths of the ocean. Unlike its more commonly discussed cousin, the 16610 (which featured a date window), the 16620 stands alone as a purist's Submariner, a no-date marvel that has captured the hearts of collectors and enthusiasts alike. This article will delve deep into the intricacies of the 16620, exploring its design, its history, its place within the broader Submariner lineage, and its current market value. While the provided categories primarily focus on the 16610, we will draw parallels and contrasts to fully appreciate the unique character of the 16620.
A Clean, Uncluttered Dial: The Hallmark of the 16620
The defining characteristic of the 16620 is its unadorned dial. The absence of a date window results in a cleaner, more symmetrical aesthetic. This minimalist design philosophy underscores the watch's purpose: to provide unwavering reliability and legibility in challenging underwater environments. The dial itself is a masterpiece of understated elegance. Large, luminous hour markers, typically applied indices, provide excellent visibility even in the darkest depths. The luminescent Chromalight display, a Rolex innovation, significantly improved visibility in low-light conditions, a crucial feature for professional divers. The hands, mirroring the markers, are generously sized and filled with the same luminous material, ensuring effortless timekeeping in any situation. The simple, clean design of the dial is a key element of the 16620's enduring appeal. It's a testament to the principle that less is often more, especially when functionality and durability are paramount.
The Robust Case and Movement: Engineering Excellence
Beyond its visually striking dial, the 16620 boasts a robust and incredibly durable case. Constructed from highly corrosion-resistant 904L stainless steel, the case is built to withstand the pressures of the deep sea. Its 40mm diameter, while seemingly modest by today's standards, provides a perfect balance between wearability and presence. The unidirectional rotating bezel, a hallmark of the Submariner line, is crucial for safe diving. Its serrated edge ensures a secure grip, even with gloved hands, while the luminous pip at 12 o'clock provides a clear reference point for tracking elapsed dive time. The screw-down crown and caseback further enhance the watch's water resistance, ensuring its reliability at significant depths.
The heart of the 16620 beats with the Calibre 3130, a self-winding mechanical movement that embodies Rolex's commitment to precision and reliability. Known for its robustness and accuracy, the 3130 is a testament to Rolex's horological expertise. Its power reserve of approximately 48 hours ensures dependable timekeeping, even when the watch is not worn for extended periods. The movement's components are meticulously crafted and rigorously tested, reflecting Rolex's unwavering dedication to quality. The movement's performance is a key factor contributing to the 16620's enduring popularity amongst collectors and enthusiasts.
