MILGAUSS
AN EFFICIENT SHIELDING SYSTEM

Features of the Milgauss

AN EFFICIENT SHIELDING SYSTEM

The first innovation at the heart of the Milgauss' resistance to magnetic interference is the shield inside its 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.

3131 MOVEMENT

Features of the Milgauss

3131 MOVEMENT

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.

GREEN SAPHIRE CRYSTAL

Features of the Milgauss

GREEN SAPHIRE CRYSTAL

A unique watch crystal in green sapphire developed in 2007 by Rolex. Scratchproof, fade-proof and available exclusively on the Milgauss. Its light green shade, tinted throughout the entire crystal, turns nearly luminescent at the bevelled edges. The result of a secret process that required years of development to master and takes weeks to produce. Not patented, as it is so difficult to make that no one else would even venture to try.
