Rolex Milgauss 40 mm 116400GV Steel Black Rolex Milgauss 40 mm 116400GV Steel Black

The Rolex Milgauss 116400GV is the definitive modern expression of an anti-magnetic sports watch with a storied scientific heritage. Originally introduced in the 1950s for engineers and scientists working in high-electromagnetic environments — including those at CERN in Geneva — the Milgauss was engineered to withstand magnetic fields of up to 1,000 gauss, a feat encoded in the very name "Milgauss" (mille meaning thousand in French). The current generation 116400GV revived this cult reference in 2007 to worldwide acclaim and has remained one of the most talked-about watches in the Rolex lineup ever since.

At the heart of the design is the reference 116400GV's most arresting feature: the green-tinted sapphire crystal, a Rolex first that exists on no other reference in the brand's catalog. This distinctive green sapphire casts a subtle but unmistakable emerald cast over the black dial, making the watch immediately identifiable from across a room. The black dial itself is clean and purposeful, complementing the watch's scientific identity while offering exceptional legibility in any lighting condition.

The 40mm oyster case is crafted from Rolex's proprietary 904L stainless steel, known for its exceptional corrosion resistance and brilliant polish. The stainless steel domed bezel sits flush and understated — no rotating bezel, no complications — keeping the focus entirely on the dial and that iconic crystal. The watch is fitted on Rolex's classic Oyster bracelet, one of the most refined and comfortable three-link steel bracelets in watchmaking, with integrated solid links and a deployant clasp for a secure, polished fit on the wrist.

The Milgauss 116400GV is powered by an automatic movement — a self-winding Rolex caliber housed within a Faraday cage of ferromagnetic alloys that shields the movement from magnetic interference. The movement winds itself via the natural motion of the wearer's wrist, requiring no manual winding under normal daily use. The oyster case provides 100 meters (330 feet) of water resistance, making this a capable everyday companion despite its scientific pedigree.

On the wrist, the 116400GV occupies a rare and coveted space in the Rolex universe: it is sporty but refined, technical but wearable, and visually unlike anything else in the brand's current collection. The 40mm diameter sits ideally on a wide range of wrist sizes, and the domed crystal gives the watch a pleasingly vintage-inspired profile that distinguishes it from the flat sapphire found on most modern sport references. Whether worn to a laboratory, a boardroom, or a weekend dinner, this watch commands attention and respect.
