Important Notice regarding importation into the United States of Rolex watches
Sotheby's cannot arrange for the delivery of Rolex watches to the United States because U.S. laws restricts the import of Rolex watches. The buyer or a designated agent may collect the property in the country of sale."

At the 2007 Basel Fair, Rolex reintroduced the Milgauss model, a tool watch that had been dormant for roughly thirty years. The new model, Ref. 116400, would take much of its refined styling from the conservative-looking Ref. 1019, the last of the vintage Milgauss line.

Originally this model was available in three variations: a white dial and clear sapphire glass, a black dial with clear sapphire glass and a black dial with green sapphire glass (such as the present example).

The new model became an instant hit with collectors who appreciated the technical merits of this anti-magnetic watch as well as the bold design of the orange lightning bolt hand.
