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. Auction and specialist records include an earlier 6543, with examples dated circa 1955; Rolex's own history dates the 6541 to 1956. The 6541 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 main documented groups are the early 6543, the 6541, the 1019, and the 116400 series, which Rolex discontinued in 2023.

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.

The early Milgauss record includes the 6543 and 6541. Auction descriptions place 6543 examples around 1955 and describe a rotating bezel and early honeycomb dials; the 6541, dated by Rolex to 1956, added the configuration associated with the lightning-bolt seconds hand. The short runs leave few surviving records. The short production run leaves few surviving records.
