The Rolex Sea-Dweller, a name synonymous with underwater exploration and horological excellence, has a rich history. While the reference number 116660 isn't officially a model designation (the correct reference for the model discussed here is 116600), the frequent misidentification highlights the watch's enduring popularity and the confusion surrounding its lineage. This article focuses on the movement powering the Rolex Sea-Dweller ref. 116600 (often mistakenly called 116660), the robust and reliable Caliber 3135, exploring its features, performance, and significance within the context of the watch itself. We'll also delve into various aspects of the Sea-Dweller 116600 (again, the correct reference), addressing common searches like "Rolex Sea-Dweller 116660 review," "Rolex 116660 price," and the differences between it and the Deepsea.
The Heart of the Beast: Rolex Caliber 3135
At the core of the Rolex Sea-Dweller ref. 116600 lies the Caliber 3135, a self-winding mechanical movement that is a testament to Rolex's commitment to precision and durability. This workhorse movement, a staple in many of Rolex's professional watches, is renowned for its reliability and accuracy. Its performance is a critical element contributing to the Sea-Dweller's reputation as a tool watch capable of withstanding extreme conditions.
The Caliber 3135 is a marvel of engineering, featuring a highly efficient self-winding mechanism via a Perpetual rotor. This system ensures the mainspring is constantly wound, minimizing the need for manual winding. The movement boasts a power reserve of approximately 48 hours, allowing the watch to continue functioning even if it's not worn for a couple of days. This is crucial for a professional diving watch, where extended periods without wear might occur.
Beyond the self-winding mechanism, the Caliber 3135 incorporates several key features that enhance its performance and longevity:
* Paramagnetic blue Parachrom hairspring: This patented hairspring, made from a paramagnetic alloy, is significantly more resistant to magnetic fields than traditional hairsprings. This is vital in an era of increasing electromagnetic interference, ensuring consistent timekeeping even in challenging environments.
* Microstella regulating screws: These tiny screws allow for precise adjustment of the balance wheel, enabling fine-tuning of the movement's accuracy. This level of adjustment contributes to the Caliber 3135's chronometric performance.
* High-precision manufacturing: Rolex's meticulous manufacturing processes ensure exceptional tolerances and tight assembly, leading to the movement's remarkable reliability. Each component is crafted to exacting standards, minimizing friction and maximizing efficiency.
* Shock resistance: The Caliber 3135 is designed to withstand significant shocks, a vital feature for a watch intended for use in demanding underwater environments. The robust construction minimizes the risk of damage from impacts.
