The Rolex Submariner, a legend in the world of horology, has undergone numerous refinements throughout its history. While the iconic design remains largely consistent, subtle changes in the movement have consistently improved accuracy, reliability, and longevity. The 2019 models, while outwardly appearing similar to their predecessors, often housed the calibre 3130 movement, a workhorse known for its robustness and precision. This article delves into the specifics of the calibre 3130, comparing it to its close relative, the calibre 3135, and exploring its place within the broader context of Submariner history and variations.
The calibre 3130, powering many reference 114060 Submariners from 2019, is a self-winding mechanical movement, a testament to Rolex's commitment to traditional watchmaking. Sharing a significant lineage with the widely acclaimed calibre 3135, it boasts a similar architecture but with key differences that contribute to its unique characteristics. Both movements are 31-jewel, automatic movements, certified by the Contrôle Officiel Suisse des Chronomètres (COSC), signifying their exceptional accuracy and precision. This certification guarantees that each movement has passed rigorous testing, ensuring that it meets COSC's stringent standards for timekeeping. This rigorous testing involves subjecting the movement to various positions and temperatures to assess its performance under different conditions. Only movements meeting these high standards receive the coveted COSC certification.
Calibre 3130 vs. Calibre 3135: A Comparative Analysis
While both movements share the same fundamental architecture and are both renowned for their reliability, there are subtle distinctions that set them apart. The most significant difference lies in their functionality. The calibre 3135, found in many other Rolex models including some Submariners and Datejusts, incorporates a date function, requiring additional components and complexity. The calibre 3130, on the other hand, is a simpler movement, focusing solely on timekeeping, eliminating the date mechanism. This simplification contributes to a slightly more robust and potentially more resilient movement, reducing the number of potential points of failure.
This simplification also translates to a slightly slimmer profile for the calibre 3130, contributing to the overall sleekness of the Submariner. The absence of the date mechanism reduces the overall thickness of the movement, making the watch more comfortable to wear. The reduced complexity also contributes to easier maintenance and potentially lower servicing costs. However, this simplicity comes at the cost of functionality – the lack of a date window is a trade-off some users might find significant.
Both movements are constructed using Rolex's proprietary materials and manufacturing techniques, ensuring exceptional durability and longevity. They feature a Parachrom hairspring, resistant to magnetic fields and temperature variations, significantly enhancing the movement's accuracy and stability over time. The high-performance Paraflex shock absorbers further protect the movement from impacts, crucial for a watch designed for demanding underwater environments. The self-winding mechanism, driven by the rotor, efficiently winds the mainspring, ensuring consistent power reserve. Both movements typically boast a power reserve of approximately 48 hours.
The meticulously crafted components of both movements, including the meticulously finished bridges and plates, showcase Rolex's commitment to quality and precision. This attention to detail is not just aesthetic; it contributes to the movement's reliability and performance. The high-quality lubricants used ensure smooth operation and longevity, reducing friction and wear over time.
