The Rolex Submariner, a legend in the world of horology, is instantly recognizable, not just for its iconic case shape or its exceptional water resistance, but also for its crown. This seemingly small detail, the winding crown, acts as a crucial interface between the wearer and the intricate mechanism within. More than just a functional component, the Submariner's crown tells a story, a story interwoven with the watch's evolution, its manufacturing techniques, and the preferences of collectors. Now, moving forward in history, you may have noticed that different Rolex watches, even within the Submariner family, have different symbols on their crowns. Some have dots, others have one dot, and some have a line. These seemingly minor variations often hold significant clues about the watch's age, provenance, and even its rarity. This article will delve deep into the intricacies of the Rolex Submariner crown, exploring its design, evolution, and the significance of its markings.
The Crown's Function and Evolution:
The Rolex Submariner crown, unlike many other watch crowns, is exceptionally robust. Its Triplock triple waterproofness system, a hallmark of Rolex engineering, ensures exceptional water resistance, a critical feature for a dive watch. This system involves three separate sealing mechanisms, making the crown incredibly resistant to water ingress, even at significant depths. The crown's screw-down mechanism is another key element, ensuring a secure seal when the watch is underwater. This secure fastening is crucial for maintaining the watch's internal pressure and preventing damage from water pressure.
The evolution of the Submariner crown reflects Rolex's continuous pursuit of improvement. Early models featured simpler crown designs, less robust than those found on later iterations. Over time, Rolex refined the crown's design, incorporating larger, more easily grippable crowns with more pronounced knurling (the textured surface for grip). This improved ergonomics made setting the time and winding the watch much easier, particularly when wearing gloves or in challenging underwater conditions.
The material of the crown also underwent changes. While early models might have utilized different materials, modern Submariner crowns are typically crafted from high-grade stainless steel, ensuring durability and resistance to corrosion. This choice of material reflects Rolex's commitment to using only the highest quality components in its watches.
Crown Markings: A Collector's Guide:
As mentioned earlier, the presence or absence of dots and lines on the crown is a significant indicator of the watch's age and model. These markings are not arbitrary; they are often associated with specific production years and model variations. For instance, some vintage Submariners feature a crown with a single dot, while others have two or even a line. These subtle differences can significantly impact a watch's value among collectors.
Understanding these markings requires a deep dive into Rolex's production history. A comprehensive Rolex winding crown position chart, readily available online and in specialized literature, can help decipher these markings. This chart provides a visual guide, correlating crown markings with specific model numbers and production years. For example, a Rolex Submariner 5512, one of the most sought-after vintage models, might exhibit particular crown markings depending on its production year. The variations in the 5512 dial variations themselves also sometimes correspond to crown markings, adding another layer of complexity and interest for collectors.
