Rolex Milgauss Oystersteel Green Crystal — Black Dial | Ref. 116400GV

The Milgauss occupies a singular niche within the Rolex catalogue — conceived in 1956 for the scientists and engineers working in environments of intense electromagnetic activity, its name literally encodes its raison d'être: mille gauss, one thousand gauss, the level of magnetic field resistance the watch was engineered to withstand. Reference 116400GV is the defining expression of the modern Milgauss, instantly identifiable through its distinctive green sapphire crystal — a horological flourish unique to this reference, the tinted crystal casting the black dial in a subtly verdigris light that amplifies the watch's otherworldly, scientific character.

The 40 mm Oystersteel case is fitted with the characteristic domed stainless steel bezel, smooth and unadorned, emphasising function over decoration. Beneath the case back, the movement is shielded by a soft ferromagnetic inner cage — a proprietary Rolex construction that deflects magnetic fields away from the oscillating components, enabling the watch to function accurately in environments that would paralyse a conventional Swiss lever escapement. Calibre 3131 — the manufacture Rolex movement developed for the Milgauss — incorporates a paramagnetic hairspring and escape wheel, providing antimagnetic performance alongside a 48-hour power reserve and COSC chronometric certification.

Supplied with full box and papers and presented in the Oyster bracelet — heavy new-style construction in Oystersteel secured by the Oysterclasp — the 116400GV carries a water resistance rating of 100 metres. For the collector drawn to Rolex watches that possess genuine scientific and engineering pedigree rather than purely social cachet, the Milgauss in green crystal configuration is irreplaceable: there is no other watch in the Rolex portfolio quite like it, and no other watch in the industry that can claim an equivalent combination of heritage, purpose, and unmistakable visual identity.
