A well-preserved 11538 Scientigraf, Eberhard’s answer to the Milgauss, with an extremely rare late production ‘Explorer’-style dial. The 38mm case sports a wide, sterile steel bezel and inner iron Faraday cage which can withstand an advertised 900-1000 Gauss. The Scientigraf was only ever made in smaller numbers relative to any other mainstream model line. Of this latter 3-6-9 dial, only three other examples are known.
