Accompanied by International Warranty dated December 6th, 2007, Milgauss pamphlet and various informational 🐠booklets. Together with a fitted leather presentation box and outer packaging.

At the 2007 Basel Fair, Rolex announced the reintroduction of 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 origi🔴nal Milgauss line.

Originally this model was available in three variations: a black dial and green sapphire glass, a white dial and clear sapphire glass and a black dial with clear 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 𒈔the orange lightning bolt hand.
