The black dial Rolex Milgauss, model number 116400, and especially the LC100 version from 2009, represents a watch specifically designed for scientists and engineers working in environments with strong magnetic fields. The name "Milgauss" derives from the watch's ability to withstand magnetic fields of up to 1,000 gauss, a feature that underlines its technical sophistication and engineering prowess. Design and aesthetics: Dial: The dial of the Milgauss is traditionally black, which provides a clear contrast to the striking orange and white accents that provide improved legibility. A distinctive feature is the seconds hand, which is designed in the shape of an orange lightning bolt, giving the watch a distinctive look. Case: The case has a diameter of 40 mm and is made of Oystersteel, a particularly corrosion-resistant alloy. The watch has a smooth, polished bezel that underlines the simple and functional design, optimized for technical purposes. Technical features: Movement: The Milgauss is powered by a Rolex Caliber 3131, a self-winding mechanical movement specially developed for its anti-magnetic properties. This caliber includes a Parachrom hairspring and a magnetic shield placed around the movement to ensure functionality in highly magnetic environments. Water resistance: The watch is water resistant to a depth of 100 meters (330 feet), making it durable enough for everyday activities and light diving. Bracelet: The bracelet is also made from Oystersteel and features an Oysterclasp clasp, ensuring a secure and adjustable fit. The robust and comfortable design of the bracelet makes the Milgauss ideal for everyday use, even in demanding environments. The 2009 Rolex Milgauss 116400 is an exceptional watch appreciated not only for its anti-magnetic properties but also for its unique design and reliability. It is ideal for professionals working in fields such as nuclear physics and electrical engineering, as well as for watch enthusiasts looking for a watch with a strong technical history and special functions.
