The Rolex Oyster Perpetual Datejust, a cornerstone of the brand's collection, has housed a variety of movements over its decades-long history. Among the most prominent are the calibers 3185 and 3187, both automatic movements renowned for their reliability and precision. While superficially similar, subtle yet significant differences exist, impacting performance, maintenance, and ultimately, the value of the watch they power. This article will delve into a comprehensive comparison of the Rolex 3185 and 3187 movements, addressing key features, differences, and addressing frequently asked questions related to these calibers.
Understanding the Rolex Caliber 3185
The Rolex caliber 3185 is a self-winding mechanical movement that served as the backbone of many Datejust models for years. Its robust construction, inherent accuracy, and proven reliability cemented its place as a benchmark in the watchmaking industry. This movement is characterized by its:
* High Precision: The 3185 is known for its exceptional timekeeping capabilities, maintaining accuracy within the strict tolerances set by Rolex. Its robust design minimizes the impact of shocks and temperature variations.
* Automatic Winding: The self-winding mechanism, using a rotor, automatically winds the mainspring, eliminating the need for manual winding. This ensures consistent power reserve.
* Date Function: A crucial feature of the Datejust, the 3185 incorporates a date display, instantaneously changing at midnight.
* Robust Construction: The movement utilizes high-quality components, including meticulously finished gears and jewels, contributing to its durability and longevity.
Rolex Caliber 3185 Review:
Numerous reviews consistently praise the 3185 for its dependability. Owners often report minimal issues over years of wear, highlighting the movement's resilience and precise timekeeping. The 3185’s enduring performance has earned it a reputation as one of Rolex’s most successful and reliable calibers. However, some older examples might require servicing due to age and wear, a common occurrence with mechanical movements regardless of brand. The longevity and ease of servicing, thanks to widely available parts, contribute to its positive reputation.
Rolex Caliber 3185 Price:
The price of a Rolex movement, whether a 3185 or any other, is rarely discussed independently. The value is intrinsically tied to the entire watch. A used Rolex Datejust with a 3185 movement will command a price influenced by factors like its condition, year of manufacture, and overall market demand. Finding the price of a 3185 movement alone is difficult, as Rolex generally doesn't sell them separately. Replacement movements, often sourced through authorized service centers, are significantly more expensive than purchasing a pre-owned complete watch.
