Rolex Milgauss 116400GV-0002: Engineered for Magnetic Environments

The Rolex Milgauss 116400GV-0002 was made for people who work around strong magnetic fields — engineers, researchers and technicians — and the Z-Blue dial version is the one most collectors picture. Its name comes from the French mille gauss, a nod to the 1,000-gauss magnetic resistance this 40 mm stainless steel watch was built to deliver.

The Z-Blue dial shifts between electric blue and deep navy as light moves across it, while the green-tinted sapphire crystal behind the "GV" suffix gives the case edge an emerald glow. A bright orange lightning-bolt seconds hand sweeps the dial, adding character to an otherwise restrained design.

Inside, an internal magnetic shield protects the movement from interference that would throw an ordinary mechanical watch off rate. The 40 mm Oyster case wears larger than its dimensions suggest, thanks to a smooth bezel and a dial that fills the aperture.

Why the Milgauss Stands Apart

The Milgauss has always been a specialist piece rather than a mainstream one, which is exactly why it appeals to buyers who already own a Datejust or a Submariner. The 116400GV pairs anti-magnetic engineering with a dial you rarely see on other wrists, making it a quieter choice in a room full of familiar references.

It works just as well as an everyday watch. The stainless steel case and Oyster bracelet handle daily knocks, the Oysterclasp includes an Easylink extension for quick comfort adjustments, and 100 m of water resistance covers rain, hand-washing and swimming.

Frequently Asked Questions

Is the Milgauss 116400GV still in production?

No. Rolex discontinued the Milgauss line in 2023, so this reference now moves through the secondary market rather than authorised dealers.

What does "GV" mean on this reference?

GV stands for glace verte, the green-tinted sapphire crystal fitted to this version. It's an aesthetic detail, but it's the one people notice first.

Is 40 mm too large for everyday wear?

It sits mid-size in the Rolex range. On a smaller wrist it reads as a substantial daily watch, and on a larger wrist it looks proportionate rather than oversized.

Does the watch need manual winding?

No. It winds automatically from wrist movement, and a full power reserve holds the watch running for roughly two days off the wrist.
