Rolex Milgauss 40 116400 Black Dial Oystersteel Watch

The Rolex Milgauss 116400 is a distinctive 40 mm Rolex Professional watch developed around the brand’s history of creating timepieces capable of resisting magnetic interference. This black-dial configuration combines an Oystersteel case with an Oyster bracelet and Rolex Calibre 3131. The Milgauss takes its name from its ability to withstand magnetic fields of up to 1,000 gauss, making magnetic resistance a defining part of the model’s identity. The 40 mm Oystersteel case features a smooth, domed bezel and a screw-down crown. The black dial is complemented by highly legible hour markers and the Milgauss’s distinctive orange lightning-bolt seconds hand. The watch is fitted with a three-piece Oyster bracelet and Oysterclasp, with an Easylink 5 mm comfort extension system. Unlike the later Milgauss 116400GV, the reference 116400 does not use the green-tinted sapphire crystal associated with the GV version.
