An original Rolex Milgauss Ref. 6541 produced in 1958 brought more than $113,000, including buyer’s premium, at today’s Bonhams auction of fine wristwatches in London. The watch, Lot 139, was originally sold by Watches of Switzerland in New Bond Street in 1962. Characterized by the “lightening strike” center seconds hand, the Milgauss was designed for use in areas subjected to high levels of electro-magnetic radiation. This example has a black honeycomb dial, “Milgauss” printed in red, a caliber 1066M movement, and a 35mm case.
