Milgauss
Oyster, 40 mm, Oystersteel

904L Stainless Steel

Model features

Rolex uses 904L stainless steel for its steel watch cases. 904L steel is mainly used in the high technology, aerospace and chemical industries, where maximum resistance to corrosion is essential. A superalloy, 904L steel is extremely resistant and highly polishable. It maintains its beauty even in the harshest environments.

A Black Dial

Model features

The Milgauss GV features a black dial with luminescent orange hour markers at 3, 6 and 9 o'clock, interspersed with white hour markers.
A green sapphire crystal – with a twist of lime – produces light reflections while preserving optimal legibility. Yet another Rolex first.

The Oyster bracelet

Model features

The design, development and production of Rolex bracelets and clasps, as well as the stringent tests they face, involve advanced high technology. And, as with all the components of the watch, aesthetic controls by the human eye guarantee impeccable beauty. The Oyster bracelet is a perfect alchemy of form and function. First introduced in the late 1930s, this particularly robust and comfortable metal bracelet with its broad, flat three-piece links remains the most universal bracelet in the Oyster collection.

3131 Movement

Model features

The Milgauss is equipped with calibre 3131, a self-winding mechanical movement entirely developed and manufactured by Rolex. It incorporates state-of-the-art technologies patented by the brand that ensure exceptional resistance to magnetic fields. Like all Rolex Perpetual movements, the 3131 is a certified Swiss chronometer, a designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute (COSC) tests. Its architecture, in common with all Oyster watch movements, makes it singularly reliable.

An efficient shielding system

Model features

The first innovation at the heart of the Milgauss' resistance to magnetic interference is the shield inside the Oyster case. Made of ferromagnetic alloys selected by Rolex, it surrounds and protects the movement. The symbol for magnetic flux density – the capital letter 'B' with an arrow – is engraved in this magnetic shield, but only Rolex-certified watchmakers will ever see it.
