The Rolex Submariner reference 5513 holds a unique place in horological history. Unlike its close cousin, the 5512, the 5513 never boasted the coveted COSC certification and its accompanying "Superlative Chronometer Officially Certified" text on the dial. This seemingly minor detail significantly impacts the watch's character and collector appeal, differentiating it from its more formally-accredited sibling. This article will delve into the intricacies of the Rolex 5513, exploring its key features, variations, history, and what makes it such a desirable and historically significant timepiece, particularly focusing on its lack of crown guards. While the absence of crown guards isn't a defining characteristic of the 5513 itself (as it shares this feature with many examples), it is a key visual element that contributes to its distinct aesthetic.
The 5513 and its Distinguishing Features: Absence of COSC Certification
To reiterate a crucial point, the most significant difference between the Rolex 5512 and the 5513 lies in their movement certification. The 5512, generally equipped with the calibre 1570 or 1575, almost invariably featured a COSC-certified movement. This meant the movement underwent rigorous testing by the Contrôle Officiel Suisse des Chronomètres (Official Swiss Chronometer Testing Institute), ensuring accuracy within strict parameters. This certification is reflected on the dial of the 5512 with the aforementioned inscription. The 5513, however, typically housed the calibre 1520 or 1530 movements, which were not COSC-certified. This doesn't imply inferior quality; rather, it points to a different production philosophy and target market. The 5513, while robust and reliable, was arguably a more utilitarian and less formally-presented piece compared to its 5512 counterpart. This difference contributes to its unique appeal amongst collectors. Many appreciate the 5513 for its understated elegance and its connection to a more rugged, less formally-dressed era of diving watches.
Rolex 5513 Gilt: A Golden Touch of History
The Rolex 5513 is renowned for its various dial variations, with gilt dials being particularly sought after. Rolex 5513 gilt dials, exhibiting a warm, golden hue, offer a beautiful contrast to the watch's steel case. The aging of these gilt dials over time creates unique patina, adding to their character and desirability. The intensity and tone of the gilt can vary considerably, influenced by factors such as the age of the watch, exposure to light, and the original manufacturing process. This variation is part of what makes each Rolex 5513 gilt dial unique and collectible. The subtle shifts in color, often described as "tropical" or "creamy," are highly valued by connoisseurs, making these dials a focal point of many 5513 collections.
