The Rolex Milgauss reference 116400GV is a distinctive timepiece celebrated for its exceptional antimagnetic capabilities, designed for professionals such as scientists and engineers exposed to strong magnetic fields. Introduced in 2007, and featuring the unique "Glace Verte" (GV) green sapphire crystal, this model is famously resistant to magnetic fields up to 1,000 gauss, achieved through a Faraday cage construction around its movement. The Z-Blue dial version, added in 2014, features a vibrant blue dial complemented by an orange lightning-bolt shaped seconds hand and orange minute markers, offering a playful yet sophisticated aesthetic. Encased in a robust 40mm Oystersteel case and paired with a comfortable Oyster bracelet, it is powered by the automatic Caliber 3131 movement, a COSC-certified chronometer, ensuring precision and reliability. The watch is water-resistant to 100 meters (330 feet) and was discontinued in 2023.
