Notes

Ref. 1019 Production of this reference started in 1966. The reference 1019 is made only with a polished bezel. Milgauss The name 'Milgauss', combines 'Mil', meaning (a thousand), and 'Gauss', for the unit of measure of magnetism. A normal movement can withstand up to 70-80 Gauss; over that its working order is compromised. Most good watches resist magnetic fields of 60 to 70 Gauss, but the 'Milgauss' keeps its astounding precision in magnetic fields up to 1000 Gauss. Yet with its dial, ring and the cover of its movement in soft iron forming a Faraday cage, Rolex created a model which brilliantly solved the problem. Carl Friedrich Gauss (1777 - 1855) German astronomer, mathematician and physicist. Author of important works on celestial mechanics, geodesy, magnetism, electromagnetism and optics. Michael Faraday (1791-1867) English chemist and physicist, known for his pioneering experiments in electricity and magnetism. Many of his concepts, derived directly from experiments, such as lines of magnetic force, have become common ideas in modern physics. Gauss - A magnetic induction unit, symbol g in the C.G.S. system.
