Honouring Science

  • A unique


  • True to its scientific heritage
    The Milgauss has remained faithful to its scientific heritage and unique identity as it has evolved. With its clean lines and evocative orange seconds hand, shaped like a lightning bolt to echo the original model, the Milgauss is recognisable at a glance.

  • The Milgauss features luminescent white or orange hour markers. A green sapphire crystal – with a twist of lime – produces light reflections while preserving optimal legibility. Yet another Rolex first.

  • Resistance
    To magnetic


  • 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 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.

  • Several key components in the movement of the new‐generation Milgauss are made of innovative paramagnetic materials, including the blue Parachrom hairspring. They were developed and are made in-house with advanced technology thanks to Rolex’s unique command of the whole watchmaking process.

  • At the Cutting
    edge of 
    Scientific research



  • 1956, CERN    
    The largest laboratory, the tiniest particle
  • The Oyster Perpetual Milgauss is a pioneering anti-magnetic watch developed in 1956, worn by scientists and engineers, namely those from the European Organization for Nuclear Research (CERN).
    CERN is the world's pre-eminent particle physics laboratory and home to the Large Hadron Collider (LHC), the world’s largest and most powerful particle accelerator.

  • 1956
    The First Milgauss
  • The European Organization for Nuclear Research (CERN) is at the cutting edge of scientific research into the fundamental secrets of the universe. In the 1950s, CERN was one of the first scientific institutions to confirm that the Milgauss watch could indeed resist magnetic fields of up to 1,000 gauss.
