Rolex MILGAUSS Oystersteel Ref #M116400GV-0001

Rolex Milgauss 40mm – Oystersteel – Ref. M116400GV-0001

Overview

The Rolex Milgauss Ref. M116400GV-0001 stands as one of Rolex’s most distinctive and iconic models, designed with the unique ability to resist magnetic fields of up to 1,000 gauss—hence the name “Mille” (thousand) and “Gauss” (magnetic field unit). First introduced in 1956 for scientists, engineers, and medical professionals working in high-magnetic environments, the Milgauss has since become a symbol of technical mastery blended with bold style.

This reference features a 40mm Oyster case in robust 904L Oystersteel, paired with a solid-link Oyster bracelet for durability and comfort. Its defining feature is the exclusive green sapphire crystal (GV – Glace Verte), unique to the Milgauss line, which gives the watch its unmistakable identity.

The intense black dial is accented with vibrant orange details—including the “Milgauss” inscription, markers, and the iconic lightning-bolt orange seconds hand. These touches lend the watch a playful, distinctive character while preserving the refined elegance expected of Rolex.

Inside beats the in-house Calibre 3131, a self-winding movement equipped with a magnetic shield, ensuring resilience in highly magnetic conditions. It delivers a power reserve of ~48 hours, and features a Parachrom hairspring and Paraflex shock absorbers, earning the title of Superlative Chronometer with precision of −2/+2 seconds per day after casing.
