The Milgauss 116400GV is Rolex's anti-magnetic tool watch, built for environments where electromagnetic fields would stop an ordinary movement cold. The green sapphire crystal, orange lightning-bolt seconds hand, and caliber 3131 with a Faraday cage make it technically singular in the catalog, and its discontinuation in 2023 closed a production run with no announced successor.
The 116400GV launched in 2007 alongside a non-green-crystal variant (116400), reviving the Milgauss name that had been dormant since the 116400's own predecessor, the ref. 1019, was discontinued in 1988. The "GV" suffix stands for "glace verte," French for green glass, referring to the distinctive green-tinted sapphire crystal unique to this reference. Rolex offered three dial configurations: black, Z-blue (a deep cyan with a wave motif), and white; the Z-blue became the most sought-after.
Production continued without significant design changes through 2023, when Rolex quietly discontinued the entire Milgauss line with no public explanation.
Check the crystal carefully: the green tint is subtle and a replaced crystal using standard clear sapphire is easy to miss indoors but obvious in daylight. The orange lightning-bolt seconds hand is a common service replacement target; confirm it is the correct hand, not a substitute from a non-GV variant or third-party supplier. Inspect the dial for moisture intrusion or service-related damage around the sub-dials, since the 100m rating is modest and older examples have seen water exposure.
Confirm the case has not been polished flat; the brushed and polished surfaces on the 116400GV case are distinct and over-polishing destroys the contrast. For bracelet matching, the Oyster bracelet on this reference uses a solid-link construction; check for stretch at the clasp end and confirm the correct folding Oysterlock clasp is present.
