The question "What is the Rolex movement called?" doesn't have a single, simple answer. Unlike some brands that might use a single movement across their entire range, Rolex boasts a diverse portfolio of in-house calibres, each with its own designation and characteristics. Understanding the nomenclature and intricacies of Rolex movements requires a deeper dive into the brand's history and manufacturing processes. A Rolex movement, like any other watch movement, is the very heart of the timepiece. It's the complex mechanism responsible for the precise and reliable timekeeping, as well as powering any additional complications the watch might possess – features such as chronographs, annual calendars, perpetual calendars, GMT functions, and date displays.
This article will explore the world of Rolex movements, examining their internal workings, their designations, notable models featuring specific movements, and address common questions surrounding their manufacture and availability.
A List of Rolex Movements:
Providing an exhaustive list of *every* Rolex movement ever produced is a monumental task. Rolex has a long and rich history of continuous innovation and refinement, leading to a vast catalog of calibres, many of which are variations or successors to earlier designs. However, we can highlight some of the most significant and commonly encountered movements:
* Calibre 3135: This is arguably Rolex's most famous movement. A robust and reliable automatic movement with a date function, it powered a significant portion of the brand's professional watches for decades. Its widespread use and proven durability have cemented its place in horological history. We'll delve deeper into this movement later in the article.
* Calibre 3235: The successor to the 3135, the 3235 boasts improved efficiency and chronometric performance. It incorporates the Chronergy escape wheel, a silicon escape wheel that contributes to increased shock resistance and reduced friction.
* Calibre 4130: Specifically designed for Rolex's Daytona chronographs, the 4130 is a highly sophisticated column-wheel chronograph movement known for its precision and reliability.
* Calibre 3255: This movement, found in several models, represents another significant step in Rolex's technological advancements. It combines the performance of the 3235 with improvements in power reserve and efficiency.
* Calibre 2236: An automatic movement often found in women's Rolex models, it is known for its smaller size and refined design.
* Calibre 7040: A quartz movement, a rarity in Rolex's primarily mechanical lineup. This highlights the brand's commitment to mechanical movements, but showcases their willingness to explore different technologies.
This list is not exhaustive, but it represents a selection of key movements that illustrate the breadth of Rolex's calibre offerings. Many other movements exist, often with subtle variations and improvements over time. Consulting official Rolex documentation or specialized watchmaking resources provides the most comprehensive list.
Rolex Movements by Model:
Understanding which movement powers a specific Rolex model is crucial for appreciating its technical capabilities and appreciating its value. The movement is often a key factor in determining a watch's price and collectability. For example:
* Submariner: Often equipped with the calibre 3135 (older models) or the 3235 (newer models).
* GMT-Master II: Typically uses variations of the calibre 3186.
