The Rolex Submariner 5512, a legendary dive watch revered by collectors and enthusiasts alike, boasts a rich history marked by subtle yet significant variations. One such detail, often overlooked yet crucial in authentication and dating, is the design of its crown guards. Depending on the production year, three distinct types of crown guards can be found on the 5512, each telling a story of the watch's evolution and reflecting the meticulous craftsmanship of Rolex. This article delves into the nuances of these crown guards, exploring their characteristics and significance within the broader context of the Rolex 5512's legacy.
Rolex 5512 Crown Guards: A Tale of Three Types
The Rolex 5512, produced from the late 1950s to the mid-1980s, underwent several subtle modifications throughout its production run. One of the most noticeable changes lies in the design of its crown guards, the protective extensions flanking the crown. These seemingly minor details provide valuable clues for discerning collectors attempting to pinpoint the exact production year of a particular watch. We can categorize the 5512 crown guards into three primary types:
1. Early Square Crown Guards (circa 1950s-early 1960s): These are characterized by their relatively short and sharply defined square shape. The angles are pronounced, creating a distinct, almost boxy appearance. The transition from the case to the crown guard is abrupt, with little to no curvature. These early guards often exhibit a slightly more pronounced "step" or transition where they meet the case. Finding a 5512 with these early square crown guards is a testament to its age and rarity, as these are among the earliest examples of the model. The machining of these early guards often shows slightly more visible tool marks, a characteristic appreciated by many vintage watch collectors.
2. Transitional Square Crown Guards (mid-1960s-late 1960s): As Rolex refined its manufacturing processes, the design of the crown guards subtly evolved. The transitional period saw a slight softening of the sharp angles found on the earliest models. The square shape remains, but the corners are slightly more rounded, resulting in a less severe and more refined aesthetic. The transition between the case and crown guard becomes slightly more smoothly integrated, although the "step" is still noticeable. Identifying these transitional guards requires a keen eye and a thorough understanding of the subtle variations between the early and later types. The tool marks on these transitional guards are often less pronounced than on the earliest examples.
3. Later Square Crown Guards (late 1960s-mid-1980s): The final iteration of the 5512's square crown guards features a more pronounced curve and a smoother transition from the case. The square shape is still present, but the corners are significantly rounded, creating a more flowing and less angular profile. The "step" between the case and crown guard is less pronounced or virtually absent in many examples. This smoother integration reflects the advancements in Rolex's manufacturing techniques over the years. These later guards often exhibit a higher degree of polish and fewer visible tool marks.
