What is the Rolex Milgauss?
The Rolex Milgauss is a luxury antimagnetic watch designed specifically for scientists, engineers, and professionals working in magnetic environments. First introduced in 1956, this Swiss timepiece represents Rolex's innovative solution to magnetic interference - one of mechanical watchmaking's greatest challenges.
The Milgauss name combines "mille" (French for thousand) and "gauss" (unit of magnetic measurement), reflecting its ability to withstand magnetic fields up to 1,000 gauss. This antimagnetic watch features Rolex's signature green sapphire crystal and distinctive orange lightning bolt seconds hand, making it instantly recognizable among luxury timepieces.
Key Features:
- Antimagnetic resistance up to 1,000 gauss
- 40mm Oystersteel case
- Green-tinted sapphire crystal (GV models)

History and Evolution
The Scientific Beginning (1956)
The Rolex Milgauss story begins with a collaboration between Rolex and CERN (European Organization for Nuclear Research). Scientists working with powerful magnetic fields needed reliable timepieces that wouldn't be affected by electromagnetic interference. Traditional mechanical watches would stop or lose accuracy when exposed to strong magnetic fields.
Rolex engineers developed an innovative Faraday cage system, encasing the movement in ferromagnetic materials that deflect magnetic fields. This antimagnetic technology made the Milgauss the world's first luxury watch designed specifically for scientific applications.
Original Reference 6541 (1956-1988)
The first-generation Milgauss featured several distinctive elements:
- 38mm case (large for the era)
- Lightning bolt seconds hand
- White or black dial options
- Antimagnetic resistance to 1,000 gauss
- Limited production numbers
Despite its technical innovation, the original Milgauss had limited commercial success outside scientific communities, leading to its discontinuation in 1988.
The Revival Era (2007-Present)
Rolex reintroduced the Milgauss in 2007 with significant updates:
Reference 116400 Features:
- Modern 40mm case sizing
- Enhanced antimagnetic protection
- Green sapphire crystal option (116400GV)
- Updated Cal. 3131 movement
- Improved water resistance (100m)
The modern Rolex Milgauss has found success among both watch collectors and professionals, establishing itself as a unique entry in Rolex's sports watch lineup.
