The Rolex 3187 movement, though not as widely discussed as some of its more prolific counterparts, represents a significant chapter in the brand's history. This article delves into the intricacies of the Rolex 3187, focusing on its jewel count, beat rate, and its place within the broader context of Rolex movements. We will explore its specifications, compare it to other Rolex calibers, and examine resources like the Ranfft database for further insights. Understanding the 3187 requires a nuanced appreciation of Rolex's commitment to precision and its evolution in watchmaking technology.
Rolex 3187 Watch: Unveiling the Mystery
The Rolex 3187 is not a movement readily identified by a specific model name like the Daytona or Submariner. Unlike calibers prominently featured in iconic Rolex lines, the 3187 represents a less visible, yet equally important, part of the brand's horological legacy. Its application within specific Rolex watches remains somewhat shrouded in mystery due to the limited publicly available information. Unlike the readily accessible data for movements like the 3135 or the 2824-2, the 3187's usage remains relatively obscure, potentially suggesting a limited production run or its integration into less widely known models. Further research into vintage Rolex catalogs and archives might be necessary to definitively pinpoint the models incorporating this caliber.
Rolex 3187 Specs: Deconstructing the Mechanism
While comprehensive technical specifications for the Rolex 3187 are scarce, we can infer certain characteristics based on its classification as a self-winding mechanical movement. The "jewels" in the designation "Rolex 3187 jewels" refer to the synthetic rubies or sapphires used in the movement's bearings. These jewels significantly reduce friction, improving the efficiency and longevity of the mechanism. The exact number of jewels used in the 3187 remains to be definitively confirmed, but based on similar Rolex movements of the era, a count in the range of 26 to 31 jewels is plausible. The higher the jewel count, generally, the more sophisticated and robust the movement.
The beat rate, or frequency at which the balance wheel oscillates, is another crucial specification. While precise data for the 3187's beat rate is unavailable, we can speculate based on comparable Rolex movements. A common beat rate for Rolex movements is 28,800 vibrations per hour (vph), or 8 beats per second. This is a relatively high frequency, contributing to improved accuracy and timekeeping precision. However, the 3187's actual beat rate could potentially differ, requiring further investigation.
Other key specifications, such as the power reserve (the length of time the watch runs on a full wind), the diameter of the movement, and the materials used in its construction, remain largely unknown without access to official Rolex documentation or detailed technical drawings. This scarcity of information underscores the challenge of researching lesser-known Rolex calibers.
