Rolex Milgauss 116400GV Green Sapphire

The Rolex Milgauss reference 116400 is notable for its resistance to magnetic fields, a characteristic that distinguishes it within the Oyster Perpetual line. This particular reference, introduced in 2007, marked a return for the Milgauss model after a hiatus, reintroducing a watch designed for professionals working in environments with strong magnetic interference. It is recognized for its clean aesthetic and technical purpose, appealing to those who value both form and function in a tool watch.

This model features a 40mm Oyster case crafted from 904L stainless steel, known for its corrosion resistance. It houses the Rolex Caliber 3131, an automatic movement equipped with a Parachrom hairspring and a paramagnetic escape wheel, contributing to its anti-magnetic properties. The watch is fitted with a smooth stainless steel bezel and a sapphire crystal, ensuring durability and legibility. It offers a power reserve of approximately 48 hours and is water-resistant to 100 meters.
