Rolex, a name synonymous with luxury and precision, boasts a rich history of in-house movements. Two of its most celebrated calibers, the 3135 and the 3255, represent different eras in the brand's relentless pursuit of horological excellence. While both are automatic, self-winding movements known for their robustness and reliability, several key differences set them apart, impacting accuracy, performance, and overall longevity. This article will delve into a comprehensive comparison of the Rolex 3135 and 3255, addressing common questions and misconceptions surrounding these iconic movements. We will also touch upon related movements, such as the 3235, clarifying their relationships and key distinctions.
Understanding the Lineage: The Rolex 3135 Movement
The Rolex caliber 3135 is a workhorse movement, a legend in its own right. Introduced in the 1980s, it served as the backbone for countless Rolex models across various lines, including the Submariner, Datejust, and GMT-Master II (pre-2018). Its robust construction, featuring a solid bridge architecture and a high level of finishing, contributed to its exceptional reliability and long lifespan. The 3135 is a relatively simple movement compared to its successor, the 3255, yet it offers impressive performance. It’s a 31-jewel movement with a frequency of 28,800 vibrations per hour (vph), offering a power reserve of approximately 48 hours.
Key Features of the 3135:
* Automatic Winding: The 3135 utilizes a highly efficient self-winding system, ensuring consistent power reserve.
* Date Function: It incorporates a date display, instantly changing at midnight.
* Paraflex Shock Absorption: The 3135, and many models using it, includes Rolex's Paraflex shock absorption system, designed to protect the delicate balance staff from impacts and jolts. This system significantly enhances the movement's robustness and resistance to damage.
* Microrotor: The 3135 employs a microrotor, which contributes to its slim profile and allows for a more compact movement.
* High-Quality Finishing: The movement showcases meticulous finishing, including Côtes de Genève, perlage, and polished screws, reflecting Rolex's commitment to craftsmanship.
