About the Movement
A-magnetic version of caliber 1570, for use in Rolex Milgauss
About the Family
The Milgauss was created in 1956 for scientists and engineers working in environments with strong electromagnetic fields — particle accelerators, power plants, and medical imaging facilities where conventional watches would lose accuracy. The name combines 'mille' (French for thousand) with 'gauss' — the unit of magnetic field strength — to indicate the watch's resistance to 1,000 gauss. The lightning bolt seconds hand, introduced on the modern reference 116400, has become the Milgauss's most distinctive visual element. The watch occupies a unique niche in the Rolex catalogue: a professional instrument designed for a specific scientific purpose, with a personality that is more playful than any other model the brand produces.
About this reference
The Rolex Milgauss 1019 was introduced in 1960. Aimed at scientists and other professionals, the watch featured an increased protection to magnetic fields. The present model has a black dial.
