60 years of Scientigraf: Eberhard & Co. revives one of the world’s first anti-magnetic watches

A little over 60 years ago, Eberhard & Co. took on a problem that was prevalent in the watch industry (or rather in the whole world): increasingly strong magnetic fields. The by-product of continuous technical progress was and still is poison for every mechanical watch.

In 1961, the solution came in the form of the first Scientigraf. At the time, this advanced model was one of the absolute trailblazers in terms of anti-magnetism in watches and – together with the Rolex Milgauss that was launched just five years earlier – paved the way for subsequent further developments.

One of the most technologically advanced watches of its time.

A cage closed on all sides provides a remedy

The magnetization of watch movements negatively affects the accuracy of the rate and can even lead to the stoppage of a timepiece in extreme cases. To effectively protect the sensitive movement against magnetic fields, Eberhard & Co. came up with a solution resembling a Faraday cage. Even though this primarily shields against electrical and not magnetic fields, the basic idea remains the same.

The soft iron cage of the new Scientigraf.

In contrast to the Faraday cage, in which an all-round enclosure made of an electrical conductor (such as a wire mesh) acts as an electrical shield, the movement of the Scientigraf is surrounded on all sides by a cage made of soft iron. This material is perfectly suited because the softer a metal is, the greater its ability to absorb magnetic waves.

The Scientigraf celebrates its 60th birthday

The “soft iron Faraday cage”, which was already used in 1961, can of course again be found in this year’s new edition. It is housed in a 41mm stainless steel case, which is water resistant to 100m. Inside ticks the automatic caliber SW300-1 from Sellita, which boasts a power reserve of 42 hours.

Each Scientigraf is tested according to the international standard ISO 764:2020 and must successfully pass both stages of the magnetic resistance test.

Design-wise, Eberhard & Co. has kept very much to the original and once again relies on polished as well as satin-finished elements, which makes the watch look neither too chic nor too sporty. The two available dial versions (see picture above) are in a matte black and are again refined by a special “Galbé” finish. The popular lollipop seconds hand is also back.

Eberhard & Co. at Montredo

Introduced by Eberhard & Co. in 1961, the Scientigraf was one of the most innovative watches of its time at the time of its launch, especially in terms of anti-magnetism. We are therefore all the more pleased to see that this history-rich Swiss brand has unveiled a new edition to mark the 60th anniversary of its initial launch.

With a price of 2,250€ for the watch on the leather strap (or 2,640€ for the stainless steel version), the new Scientigraf is certainly in a highly competitive environment. However, given the technology built in, the rich history of the collection, and the resulting cult status, we feel the price is more than justified.

If you are interested in this novelty, we invite you to take a look in our shop. As an official Eberhard & Co. partner, we even offer a third year warranty.

Right this way for the new Scientigraf and our Eberhard & Co. boutique.
