The ROLEX MILGAUSS REF. 1019 was manufactured as an anti-magnetic wristwatch from 1966 until the 1980’s for use by particle researchers and members of other professions which encounter high levels of magnetism. Most watches will be affected by magnetism at around 40 gauss (a unit of measure for magnetism); the 1019 remained accurate at 1000 gauss. Hence the name MIL (one thousand) Gauss. The model underwent several dial variations. The first examples had Rolex in smaller print and Milgauss larger; later the word Rolex was larger. The early versions were offered with either a black or silvered dial with luminous hands and outer dots. Later examples, available with silver or black dials, had luminescent material applied directly to the hour markers. This dial variation is thought to have been created in conjunction with the CERN particle research facility headquartered outside Geneva; it was designed without any luminescent material. The present example preserved in very nice condition with very rare CERN dial, inclined bezel, soft iron gilt metal antimagnetic protecting cap forming a Faraday cage, screw-down case back and crown, inner case stamped II.67.
