Rolex Watches running fast
The basic innovation in the Rolex Milgauss is the use of a Faraday cage that encloses the movement. A Faraday cage (ferromagnetic enclosure) around the movement will divert a current or magnetic field and shield and protect the entire movement, including the balance wheel and its hairspring. For complete safety, the whole movement must be enclosed in the cage. However, you need to allow a number of holes to be present, otherwise you cannot attached the watch hands or the crown that protrudes out of the cage. Unfortunately, this weakens the protection. Hence the lack of a date window for the Milgauss to reduce such weaknesses.
It is also worth noting that the Milgauss GV does not sport the laser etched coronet at 6 o'clock in the crystal. A lot of reviews on the GV version tends to report erroneously about this or not at all and this could cause misinformation. Below is the technical design on this aspect for reference. The other two Milgauss models (both named "116400", too, but without the GV nomenclature) both sport the laser etched coronet. The diagram below also shows the double case-back, one for the main case and the other for the inner Faraday case.
The Milgauss GV's dial is matte grey and have indices at 3, 6 and 9 that are orange coloured while the the other markers are white. The seconds hand is a "Lightning Bolt" design in orange. The lume of the Milgauss GV is quite special. The orange markers actually emit blue light in the dark while the white markers emit green light. There is no lume on the seconds hand.
The Milgauss, like all of Rolex's professional watches, is based on the famous oyster perpetual case. Made using polished 904L steel with a polished smooth bezel. The case is 40 mm with lug to lug length of 48 mm. Due to the Faraday cage, this watch is on the heavy side, around 157 gm.
