The Rolex Submariner, a legend in the world of horology, is renowned for its robustness, reliability, and timeless design. While not explicitly advertised as featuring a neodymium magnet in its movement, the discussion surrounding magnetism and its impact on watch performance, particularly within the context of other Rolex models like the Milgauss, warrants a deeper exploration. This article will delve into the intricacies of magnetic shielding in Rolex watches, focusing on the Submariner's inherent resistance to magnetic fields, and how this contributes to its enduring value and price appreciation over time. We'll also compare its magnetic protection to that of other Rolex models and explore the role of neodymium magnets in higher-resistance watches like the Omega Seamaster Planet Ocean.
The Rolex Magnet: A Subtle but Crucial Component
While the Rolex Submariner doesn't prominently feature a neodymium magnet as a specific component of its movement, the watch's overall construction and material choices provide significant protection against magnetic fields. The magnetism resistance isn't achieved through a single, powerful neodymium magnet, but rather through a combination of factors:
* Ferromagnetic Materials: The use of carefully selected ferromagnetic materials in the movement construction minimizes the impact of external magnetic fields. These materials are chosen for their resistance to magnetization and their ability to shield the delicate components of the movement from interference. The precise alloys and their arrangement are proprietary Rolex information, contributing to the brand's reputation for precision and reliability.
* Movement Design & Shielding: The intricate design of the Submariner movement itself plays a crucial role in its magnetic resistance. Components are strategically arranged to minimize the influence of magnetic fields on the delicate balance wheel and hairspring, the heart of the timekeeping mechanism. While not a dedicated Faraday cage, the overall case construction and movement architecture provide a degree of passive shielding.
* Paramagnetic Materials: In addition to ferromagnetic materials, Rolex also utilizes paramagnetic materials. These materials are less susceptible to being magnetized than ferromagnetic materials, further reducing the potential for interference from external magnetic fields.
The absence of a large, visible neodymium magnet in the Submariner doesn't diminish its resistance to magnetism. Rather, it signifies a different approach, prioritizing a robust, integrated design over a single, powerful counteracting magnet. This design philosophy has proven highly effective over decades, contributing to the Submariner’s exceptional reliability and longevity.
The Rolex Milgauss: A Dedicated Magnetic Shield
In contrast to the Submariner's implicit magnetic resistance, the Rolex Milgauss explicitly incorporates a magnetic shielding system. The Rolex Milgauss watch, and its gauge-like appearance, is specifically designed to withstand magnetic fields up to 1,000 Gauss. This substantial protection is achieved through a soft iron inner case that acts as a Faraday cage, diverting magnetic fields away from the delicate movement components. While the Milgauss might not use a neodymium magnet itself for its shielding, the soft iron inner case effectively performs the same function—protecting the watch's timekeeping accuracy. The Milgauss showcases Rolex's commitment to addressing magnetic interference, albeit through a different approach than the Submariner's implicit resilience.
