The Rolex Submariner, a legend in the world of dive watches, owes much of its enduring reputation to the robust and reliable movement ticking within its heart: the caliber 3135. This automatic mechanical movement, a cornerstone of Rolex's production for decades, has powered countless Submariners and other prestigious Rolex models, solidifying its place as one of the most recognizable and respected watch movements ever created. While it has since been superseded by the newer 3235, the 3135 remains a highly sought-after and valuable component, both in functioning watches and as a sought-after part for restoration and servicing. This article will delve into the intricacies of the Rolex 3135, addressing its key features, common misconceptions, and various aspects relevant to its ownership, maintenance, and market value.
Understanding the Rolex Caliber 3135: Power Reserve and Beyond
The Rolex 3135 is a self-winding mechanical movement boasting a robust design built to withstand the rigors of daily wear and, crucially, the harsh conditions for which the Submariner was intended. One of its key specifications often cited is its power reserve. While officially stated as approximately 48 hours, many online sources incorrectly round this figure up to 50 hours. This slight discrepancy highlights the importance of relying on official Rolex documentation or reputable sources for precise technical specifications. The actual power reserve can also vary slightly depending on the individual movement's condition, wear, and the activity level of the wearer. A fully wound 3135 will provide approximately 48 hours of continuous operation before needing to be wound again, a testament to its efficient design and power storage capabilities.
Beyond the power reserve, the 3135 incorporates several other key features that contribute to its reliability and accuracy. These include:
* Paramagnetic blue Parachrom hairspring: This unique hairspring, made from a paramagnetic alloy, is highly resistant to magnetic fields, a significant improvement over traditional hairsprings. This resistance to magnetism contributes to the movement's overall accuracy and stability, ensuring consistent timekeeping even in environments with strong magnetic fields.
* Microstella regulating screws: These screws, found on the balance wheel, allow for precise adjustment of the movement's rate, enabling watchmakers to fine-tune the timekeeping accuracy to exceptional levels.
* KIF shock absorbers: These protect the delicate balance staff from the shocks and vibrations that a watch inevitably experiences during daily wear, contributing to the movement's longevity and resilience.
* Automatic winding system: The self-winding mechanism efficiently winds the mainspring through the movement of the wearer's wrist, eliminating the need for manual winding in most situations. This automatic winding system is highly efficient and robust, contributing to the movement's long-lasting performance.
* Date function: The 3135 movement features a date display, a practical and popular complication found in many Rolex models. The date is instantly changed at midnight, a smooth and reliable function integral to the watch's user experience.
