The Oyster Perpetual Milgauss, unveiled in 1956, is a tribute to Rolex’s historic links with scientific research, engineered to maintain exceptional chronometric precision without compromising its timeless aesthetic, thanks to a patented magnetic shield that protects the movement.
This 40mm model, from 2022, features a blue dial encased beneath sapphire crystal, secured by a smooth bezel. Its Oyster bracelet and Oysterclasp ensure wearability and stability, while its Calibre 3131 movement offers anti-magnetic resilience with uncompromised chronometric accuracy and an approximate 48-hour power reserve.
