The present Rolex Oyster Perpetual Milgauss reference 6541 represents one of the most elusive and historically significant professional models ever created by the manufacture. Conceived in the late 1950s for scientists and engineers working in environments saturated with magnetic fields, the reference 6541 introduced the now-legendary Milgauss name and firmly established the model as Rolex’s definitive anti-magnetic wristwatch.

This example displays the unmistakable traits that define the earliest chapter of Milgauss history: the black honeycomb dial with its intricate texture, the rotating bezel calibrated to 60 units, and the celebrated lightning-bolt seconds hand that has become an enduring emblem of the model. Although the luminous material on the dial has been professionally restored, the watch retains its essential authenticity, allowing its technical purpose and visual identity to remain fully appreciated.

Preserved with its period-correct Oyster riveted bracelet, the present reference 6541 stands as a rare survivor of one of the most innovative and visually striking creations in Rolex’s mid-century production. Treasured by collectors for its rarity, scientific pedigree and unmistakable design language, the 6541 continues to embody the pioneering spirit that shaped the earliest generation of Rolex’s professional tool watches.
