Rolex Milgauss 40mm 116400 Black Dial

The Rolex Milgauss 116400 is a distinctive model that reflects Rolex’s rare foray into scientific tool watches, reintroduced in 2007 after nearly two decades of absence. Designed to withstand magnetic fields up to 1,000 gauss, it houses the robust Caliber 3131 automatic movement with a paramagnetic blue Parachrom hairspring and a protective alloy shield, ensuring accuracy in environments that challenge ordinary timepieces. The watch features a 40mm stainless steel case, just over 13mm thick, paired with an Oyster bracelet. Its black dial is accented by striking orange lume markers, a minutes track with orange highlights, and the signature lightning bolt seconds hand—a bold flourish from the otherwise reserved brand. While overshadowed by the anniversary “GV” green crystal model, the discontinued black dial variant offers a crisp, understated aesthetic. Collectible for its rarity and quirky charm, the Milgauss 116400 remains a unique, science-inspired Rolex with lasting appeal.
