The Rolex Submariner 5513. The name alone conjures images of rugged exploration, daring underwater adventures, and a timeless elegance that transcends fleeting trends. A cornerstone of Rolex's history, the 5513 holds a special place in the hearts of collectors and enthusiasts alike, largely due to its robust construction, enduring design, and, significantly, its use of tritium luminous material. Unlike later models, every single example of the Rolex 5513 utilized either tritium or, in the very earliest production runs, radium for its luminous hour markers and hands. This fact, coupled with its long production run and diverse dial variations, makes the 5513 a fascinating and complex watch to study. This article will delve deep into the world of the Rolex 5513 tritium, exploring its history, variations, and the factors that contribute to its enduring appeal and significant value.
The Significance of Tritium in the 5513:
Before diving into the specifics of the 5513, it's crucial to understand the role of tritium. Tritium, a radioactive isotope of hydrogen, was widely used in watchmaking from the 1950s through the 1990s as a luminous material. It offered a significantly longer lifespan and brighter glow than earlier radium-based paints, making it ideal for professional-grade instruments like the Submariner. Rolex, a pioneer in watchmaking technology, readily adopted tritium, incorporating it into the 5513 throughout its extensive production run. The eventual abandonment of tritium by Rolex in favor of LumiNova, a non-radioactive luminescent material, occurred *after* the 5513 was discontinued. This means that every single 5513 ever produced features either tritium or radium lume – a key characteristic that sets it apart from subsequent Submariner models.
The distinctive glow of tritium in a 5513 is a highly sought-after feature amongst collectors. Over time, the tritium decays, resulting in a unique patina that varies depending on the age of the watch and its exposure to light and environmental factors. This aging process is often referred to as "tritium lume aging" and can range from a creamy, yellowish hue to a rich, brown or even almost black tone. The variation in lume aging contributes significantly to the individuality and character of each 5513, making no two watches exactly alike. This unique characteristic is a significant part of the watch's appeal, with many collectors actively seeking out examples exhibiting specific shades of aged tritium.
Rolex 5513 Dial Variations: A Collector's Paradise:
The dial is arguably the most visually striking element of the 5513, and its variations contribute significantly to the watch's collectibility. The simplicity of the design, with its clear, uncluttered layout, belies the subtle yet significant differences found across various production years. Understanding these variations is key to appreciating the complexity and depth of the 5513's history.
