Rolex Milgauss Z-Blue

About this reference

The Rolex Milgauss reference 116400GV with the Z-Blue dial was introduced in 2014 and remained in production until the entire Milgauss line was discontinued in 2023. Collectors target this reference for its electric blue sunray dial and the green-tinted sapphire crystal, a feature unique to the Milgauss collection. The 40mm stainless steel case houses an internal soft-iron Faraday cage to protect the caliber 3131 movement from magnetic fields up to 1,000 gauss. It also features a distinctive orange lightning bolt seconds hand. On the secondary market, prices typically range from $11,000 to $15,000 depending on condition and the presence of original documentation. While the 116400GV was also produced with a black dial, the Z-Blue variant often commands a premium due to its shorter production window and specific aesthetic profile within the professional model range.
