The Milgauss is ~~Rolex's~~ antimagnetic tool watch. ~~The line began in 1956 with the 6541, whose movement sat inside a soft-iron shield rated~~ to ~~1,000 gauss.~~ Rolex ~~links~~ the ~~model~~ to ~~scientists working around magnetic equipment and says researchers at CERN tested early examples~~. The ~~family has three main reference groups: 6541,~~ 1019, and the 116400 series~~, which~~ Rolex discontinued in 2023.

The Milgauss is Rolex’s antimagnetic tool watch. Christie’s dates two ref. 6543 examples to around 1955; Rolex dates the 6541 to 1956. The line continued with the 1019 and returned as the 116400 series in 2007. Rolex discontinued the latter in 2023 and says CERN researchers tested early Milgauss watches.

The defining construction is the shield. A soft-iron ring and a matching cover surround the movement and give magnetic flux a path around the regulating parts. The case and movement details changed over time, but that protection remained the reason for the Milgauss name.

== ~~Vintage~~ tool-watch ~~era~~: 6541 (~~1956–1960~~) ==

== Early tool-watch references: 6543 and 6541 (c.1955–1960) ==

~~The first cataloged Milgauss used a~~ honeycomb ~~gilt dial on a webbed laminated copper plate, a~~ lightning-bolt ~~seconds hand~~, ~~a rotating engraved~~ bezel, and ~~a Twinlock crown~~. The ~~short production run leaves few surviving records. Surviving 6541s are generally associated with early~~ 412xxx ~~serials~~, but ~~the serial evidence~~ is too ~~limited~~ to ~~treat that range~~ as ~~an absolute~~ rule.

Christie’s dates two 6543 examples to circa 1955 and describes honeycomb dials and rotating bezels. Rolex dates the 6541 to 1956; auction records document lightning-bolt hands, honeycomb dials and more than one bezel and movement configuration. The 6541 case numbers cluster around 412xxx in the examples reviewed here, but that sample is too small to serve as a serial-year rule.

* 1956: Rolex dates the 6541 to this year. The lightning-bolt seconds hand appears during the early run; surviving caseback stamps help date individual examples.

* 1960: The 6541 ends and the 1019 appears. The references may overlap in surviving stock.

* 1963 to 1965: Jake Ehrlich's Rolex Magazine archive reports 6541 watches presented to several Daytona Continental race winners. The race results are independently documented; the prize-watch details rely on that archive account.
