Rolex Milgauss 116400GV

A Simple Guide to the Iconic Rolex Milgauss and its Incredible Features

Brief history of the Rolex Milgauss

We all know that Rolex likes to dive into niches and the Milgauss is no different. Telecommunications, medical technology, aerospace and electrotechnical are just a few industries impacted by magnetic fields. Magnetic fields can disrupt the function of a mechanical watch. To counter this problem, Rolex introduced the Milgauss, which showcases a shield inside the oyster case crafted from ferromagnetic alloys that help to protect the movement from disrupting magnetic fields. The word Milguass can be broken down into Milli-Gauss, translating to 1000 gauss, the watch's resistance to magnetic density. Put simply, the watch can withstand 1000 gauss before it is affected.

The Milguass was introduced in 1956, 9 years into the cold war, when nuclear and weapon development was at its peak. The Rolex Milguass had been spotted on nuclear research scientists in Geneva at CERN, a nuclear research organisation.

The signature features of the Rolex Milgauss

When it was first introduced in 1956, the Rolex Milgauss boasted a 38mm case size which has now been replaced by an even larger 40mm. The Milgauss has only ever been made of Rolex's Oystersteel and features an Oyster 3 link bracelet; this makes sense considering its original intent as a watch for antimagnetic environments. 

The impressive green sapphire glass is an exclusive feature of the Rolex Milgauss and looks even better in real life, not to mention it doesn't fade or scratch. Another exclusive Milgauss feature is the lighting bolt on the second hand. This can be found on every Rolex Milgauss except for the reference number 1019, a vintage and discontinued model.


This watch has only ever been spotted with two bezels. The smooth bezel is found on every model except the 6541, which features a black rotating Aluminium bezel designed to be used as a timer. The smooth bezel completes the overall roundness and fantastic aesthetic of the watch.

Current configuration 

The Rolex Milgauss is currently only sold in 2 configurations. One has a black dial, and one has a Z-blue dial; they share the reference number m116400gv. The blue dial is stunning and dances under the light, whereas the intense black dial is more subtle and perfectly goes with the beautifully contrasting orange and green. Rolex use to produce the 40mm Milgauss under the same 116400 reference in with a white dial but it has since been discontinued.


The Automatic movement behind the Milgauss is the 3131. It has a high precision of +/-2 seconds per day, roughly 48 hours of power reserve and is made by Rolex. The Calibre 3131 is only used in one other Rolex watch known as the Rolex Air King 116900.

The Milgauss was originally made for scientists but now it's also a highly sought-after and unique watch. As we write this blog, the Rolex Milgauss 116400GV is still in production but there are rumours in the watch industry that this model is set to be discontinued. If Rolex discontinue the 116400 Milgauss, it's likely it will be replaced by an updated model which could have a model number of 126900.
