Eberhard enhances its anti-magnetic Scientigraf watch

1

Eberhard & Co was one of the early adopters of a Faraday cage to protect the delicate balance of their mechanical movements from the effects of magnetic fields when it created its Scientigraf watch in 1961.

The Faraday cage is a simple concept. Magnetic fields affect watch precision because parts in a movement are made from different metals that respond differently to the force.

For example, a magnet will have almost no attraction to copper gold but a strong attraction to steel.

Iron is at the end of the scale with the greatest attraction, which is why it is used to absorb magnetism in a Faraday cage.

Precision is less prized in traditional mechanical watchmaking today than it was back in the pre-quartz days of the early 1960s, but magnetic fields are a much bigger problem because of all the electronics we now use.

That is why Eberhard continues to reissue the Scientigraf, and has a new steel on steel pilot-style model for 2021 in a 41mm 100 meter water resistant steel case.

There is also the option of a fabric strap.

The latest models will be unveiled later this month to American buyers at Couture in Las Vegas.

  1. “Precision is less prized in traditional mechanical watchmaking today than it was back in the pre-quartz days of the early 1960s”.

    Don’t these articles get editor checked before print? Can one believe anything from an author who makes the above statement? There is no comparison between watches of the 60’s and the accuracy of today’s watches from top tier players and anyone remotely interested in the industry is aware of that fact!
