Rolex Milgauss: value and pre-owned prices since it was discontinued (2026)

The Milgauss has always held a special place at Rolex: a watch designed to withstand magnetic fields, with an orange lightning-bolt seconds hand and, on some versions, a green-tinted sapphire crystal that only the brand offers. In 2023 Rolex removed it from the catalogue at Watches and Wonders, without any particular announcement and without a replacement. Three years later, what is a pre-owned Milgauss worth, and has the discontinuation pushed its price up as so many listings promise? Here are the references, the ranges recorded in 2026 and the points to check before buying.

An anti-magnetic watch, three eras

The Milgauss was born in 1956 for engineers and scientists exposed to strong magnetic fields, notably at CERN. Its name comes from its stated resistance to 1,000 gauss, achieved with a soft-iron cage around the movement. Magnetism is the quiet enemy of mechanical watches: it disturbs the hairspring and makes the watch gain or lose time for no apparent reason.

For valuation purposes, three eras matter:

• The first references (notably the 6541), from 1956 to 1960, made in very small numbers and now auction pieces.
• The 1019, from 1960 to 1988: 38 mm, a sober dial with no lightning bolt, a long and discreet career. It now belongs to the vintage market.
• The modern 116400 generation, from 2007 to 2023: 40 mm, calibre 3131 with a blue Parachrom hairspring, about 48 hours of power reserve, orange lightning-bolt seconds hand. It accounts for most of the pre-owned market.

The modern references in detail

The 116400 generation splits into two families, depending on the crystal:

• The 116400 with clear crystal, launched in 2007 with a black or white dial. According to dealer records, the black dial left the catalogue around 2014 and the white around 2016: sources disagree on the exact year, as Rolex does not publish its discontinuations.
• The 116400GV with green crystal ("GV" for glace verte), launched in 2007 for the model's 50th anniversary with a black dial, then offered from 2014 with the electric blue dial nicknamed "Z-Blue". It was the only version produced until the 2023 discontinuation.

Both GV versions share the same reference: the dial distinguishes them, and the dial drives the price gap. We treat them as dial variants within a single reference, a frequent situation at Rolex.

2026 price grid

The ranges below reflect the core of listings recorded between May and October 2026, dealers and private sellers combined, for watches in good condition. They exclude damaged examples and asking prices clearly out of line with the market.

Three readings. First, the Z-Blue is the most expensive, about €2,000 ahead of the black GV: it is the most recognisable dial, and it was only produced with the green crystal. Second, the clear-crystal 116400 is the entry point, from about €7,200: it appeals to those who want the silhouette without paying for the green crystal. Finally, the white dial is rare in our data; its prices rest on too few listings to be interpreted. For a range tailored to your own watch, see the Milgauss page and the valuation tool.

Did the discontinuation push the Milgauss up?

Less than listings suggest. On paper, the Milgauss has the most favourable configuration: the whole family discontinued, no replacement, a distinctive design. But it lacks the main condition: before 2023 it was far easier to obtain in boutiques than a Submariner or a GMT-Master II, and it did not sell with the premium over retail of the most sought-after models. An available watch does not become rare overnight: more than fifteen years of production have left plentiful pre-owned supply.

The market therefore draws a clear line between versions. The Z-Blue and the black GV, produced until the end and more identifiable, have gained collectors' interest; the clear-crystal 116400 remains the most affordable Milgauss. We develop these mechanisms, with examples, in our article does a discontinued reference gain value?.

Be wary of listing titles that turn the discontinuation into an argument in itself: in our data, "discontinued" appears in a large number of Milgauss listings, whatever their price. The only reliable benchmark remains comparison with comparable examples: same dial, same crystal, same completeness.

Points to check before buying

The Milgauss is a robust watch, but several details affect its value and must be checked.

1. The green crystal. On a 116400GV it should show a visible green tint at certain angles. A clear replacement crystal fitted outside the Rolex network takes away a significant part of the value. The original green crystal is expensive to replace and is ordered from the brand.
2. Dial and reference consistency. The Z-Blue dial only exists on the 116400GV. A blue dial on a clear-crystal 116400 is an anomaly, the sign of a watch assembled from mixed parts: the very definition of a frankenwatch.
3. The anti-magnetic protection. The soft-iron cage must stay in place during servicing; it is what justifies the watch's name. Ask for the service history and, if possible, an invoice from a Rolex service centre.
4. The bezel and case. The smooth polished bezel scratches quickly. Heavy polishing rounds off the edges and takes 5 to 10% off the value of a collectible watch.
5. The serial number and the card. The first modern Milgauss carry letter-prefixed serials (Z, M, V or G series depending on the year); from around 2010 Rolex adopted the random serial number, which no longer allows the watch to be dated. The warranty card then becomes the only proof of the year.

On that last point, the full set has counted for more since the discontinuation: a complete Milgauss, with box, booklets and card, sells faster and for more than the watch alone. Our article on box and papers details the gap.

Milgauss or an alternative still in production?

If it is the anti-magnetic protection that appeals to you, the Milgauss is not the only option. The Air-King, still in production, is the closest Rolex in technical spirit, with a Parachrom hairspring the brand describes as insensitive to magnetic fields. Outside Rolex, other houses have taken a different route: the silicon hairspring, non-magnetic by nature, now equips many calibres, notably at Omega. If it is the Milgauss itself you like, with its lightning bolt and green crystal, no new watch replaces it: pre-owned is the only route, and that is what supports its value.

For a sporty Rolex at a comparable price, the Explorer II, which also went through a discontinued reference with the 216570, offers another point of comparison, covered in our Explorer II comparison.

Selling a Milgauss in 2026

The market is active for complete, unpolished Milgauss, especially with the Z-Blue dial. A few tips:

• Describe the version precisely: reference, dial colour, type of crystal, year on the card. "Milgauss" alone attracts offers at the bottom of the range.
• Do not have the watch polished before selling it, and keep the original parts if a service replaced any component.
• Compare channels: buy-back by a dealer, consignment or direct sale, as we explain in our comparison of where to sell your watch.

In France, a watch sold for more than €5,000 by a private individual is subject to the 6.5% flat-rate tax, unless the seller opts for the capital gains regime with proof of purchase. If you are selling from another country, check the rules that apply there.

In summary

The Milgauss 116400 has not become a speculative watch since it was discontinued in 2023, but it has found its place: the Z-Blue at the top, around €12,100 to €13,400, the black GV just behind, and the clear-crystal version as the entry point. The original green crystal, dial consistency and the full set account for most of the gap between two examples. Before buying or selling, calculate your Milgauss's value: the reference, the year, the condition and the accessories are enough to obtain a range based on our market data.
