Rolex 116400 Milgauss

The Rolex Milgauss 116400 marked the triumphant return of the Milgauss in 2007. Built for engineers and scientists, it blends everyday versatility with real technical purpose: anti-magnetic resistance via a soft-iron inner shield and paramagnetic components. The 40mm case, smooth bezel, and the iconic orange lightning-bolt seconds hand make it instantly recognizable. The non-GV 116400 (clear crystal) sits alongside the famous 116400GV “Glace Verte” (green crystal) in modern Rolex lore.
