Originally launched in 1961, followed by a ‘time-only’ in 2021, this Eberhard & Co. Scientigraf Chrono is the new chronograph. And just like the original, it is executed with a Faraday cage inside. In 1961 it was a technical highlight to protect a watch against magnetic fields and other forms of electromagnetic waves by using a soft iron case inside the watch case. Brands like Rolex (Milgauss in 1956), Omega (Railmaster in 1957) and IWC (Ingenieur in 1955) also dealt with this phenomenon but today the necessarily is a bit superfluous.
The design of the Scientigraf Chrono is inspired by the original from 1961, with a comparable dial layout and color use. The 1961 Eberhard & Co. Scientigraf (reference 11538) has a 38-millimeter case, this new chronograph is housed in a 41-millimeter case. It has a polished steel bezel and a black dégradé dial. The hour and minute hands and the Arabic numerals and indexes are filled with either vintage ivory colored luminescent material or orange. So, there are two version. The hour hand shows the original triangular tip, while the baton hand only has a baton shape.
The Eberhard & Co. Scientigraf Chrono has a power reserve of 42 hours
The chronograph has two counters, adorned with a refined azurée finish. You can see the 30-minute counter at 9 o’clock and the seconds counter at 3 o’clock, both with triangular tipped counter hands. It has a screw-on crown and a steel screw-on case back, with engraving taken from the 1961 model: magnetic fields with the letter “E” at the center. The water resistance is 50 meters / 165 feet.
Inside the Eberhard & Co. Scientigraf Chrono is probably an automatic Eberhard & Co. caliber EB.200 (base ETA 2894-2). For some unknown reason the brand does not often specify their movements. Nor the power reserve, which is assumably 42 hours. Both models come on a stainless steel bracelet.
