The Rolex caliber 3185 is a highly regarded automatic movement, a cornerstone of many iconic Rolex models. Its robust construction, reliable performance, and impressive accuracy have cemented its place as a benchmark in the Swiss watchmaking industry. This article will delve into the detailed specifications of the Rolex 3185, comparing it to its successor, the 3186, and addressing common misconceptions. We'll explore its presence across various Rolex models and dissect its place within the broader Rolex movement family.
Rolex Model 3185:
The Rolex caliber 3185 isn't a model in itself; rather, it's the *movement* powering a range of Rolex models. It's not affixed to a specific watch design, but rather serves as the engine within various Oyster Perpetual, Datejust, and other collections. This means you won't find a watch explicitly named "Rolex 3185." Instead, the caliber number is revealed through the watch's case back engraving or through service documentation. The specific model number of the *watch* will depend on case size, material, dial configuration, bracelet type, and other aesthetic features. Understanding the 3185's presence is key to appreciating the history and lineage of many popular Rolex timepieces.
Rolex Cal 3185:
The Rolex caliber 3185 is a self-winding (automatic) mechanical movement. This means it uses the natural movement of the wearer's wrist to wind the mainspring, eliminating the need for manual winding. Key specifications include:
* Jewels: Typically 31 jewels. These synthetic rubies reduce friction in the movement, enhancing efficiency and longevity.
* Oscillator: A Glucydur balance wheel, known for its temperature compensation properties, ensuring consistent timekeeping across varying temperatures. This is paired with a KIF Parechoc shock absorber system, protecting the delicate balance wheel from impacts.
* Escapement: A lever escapement, a common and reliable mechanism found in many high-quality mechanical watches.
* Power Reserve: Approximately 48 hours. This allows the watch to continue running for two days even if it's not worn.
* Frequency: 28,800 vibrations per hour (8 beats per second). This is a standard frequency for many high-end mechanical movements, contributing to accuracy.
* Functions: Hours, minutes, seconds, and a quickset date. The quickset date function allows the date to be adjusted rapidly using the crown, without having to cycle through the entire date range. This is a significant improvement over movements requiring multiple crown rotations for date adjustment.
* Construction: The movement is meticulously crafted with high-quality components and materials, reflecting Rolex's commitment to precision and durability. The bridges and plates are typically made of high-grade brass, often decorated with Côtes de Genève (Geneva stripes) for an enhanced aesthetic.
