Wow. Thanks for sharing, OP!

I'm inclined to disagree. I think they will absolutely bring a Milguass back on account of this (or comparable). No way they just let this slide into regular production without some amount of fanfare. It's a big deal.

In all fairness, I also think it will eventually make it into all or most models. Maybe rather quickly even.

I didn’t say they were the same watch. I said they use the same case. Which is shielded with a soft iron core. Which is undeniably true. We’re talking about antimagnetism. And as far as that goes the Air King and are the same. Green Crystal and polish and dial don’t make a bit of difference in any-magnetism. |

Among many technically relevant details, the Rolex patent application(Demande de Brevet) states the following: "The measurements were carried out using a superconducting magnet from Oxford Instruments, which can apply a magnetic field of up to 12 T (120,000 G) with a field homogeneity of < ± 2%. The working gas temperature was 20±2°C." "The invention proposes an inertial element enabling a watch movement to operate without stopping under an intense magnetic field, in particular a magnetic field with an intensity of 8'000 G, or even 15'000 G, or even 20'000 G, or even 30'000 G, while ensuring a residual rate of less than 1 s/d after such exposure." Interestingly, they reached "only" 4 T (40.000 G) even though the instrument could go up to a maximum field of 12 T. The experiment was successful, and the caliber worked inside a magnetic field of up to 4 T, but not higher. From that I conclude that this patent application is (only) the first step to develop a watch that can resist much higher magnetic fields than 4 T, 6 T, 8 T, 10 T, or even 12 T. I can see a development comparable with the Rolex Deepsea Challenge (waterproof to 11,000 metres / 36,090 feet), which holds (as far as I know) the world record depth for professional dive watches. The same is going to happen with this invention. Rolex wants to obtain the world record for a watch that still works (with a certain accuracy) in a VERY high magnetic field, i.e., larger than 16 T (16.000 Gauss). The needed superconducting magnet is a very special one but can be built. The ultimate aim is not to design and build a new Milgauss, or a comparable watch of this type, but to research and develop a new movement, integrated into a new watch design, which exceeds what a competitor reached some years ago. During this Rolex development, which will take years, any improvements can be used either for already existing or future new watch models. The final R&D goal is a different though. All above is what I conclude from the patent application; research and development will certainly not stop at 4 T, and not serve to build a (much) better new Milgauss. That would be too simple for Rolex. They research for a 17-20 T resistant watch to obtain a new world record, like for the Deepsea Challenge. Yes, it is a BIG DEAL, imho. If any customer needs a 20 T magnetic field resistant watch is a completely different discussion. |

This is the part I never understood but would like to. The soft iron core is VERY magnetic, easily magnetized. Wouldn't it influence the watches movement if magnetized? Or would the fact that it was evenly magnetized cancel this out?

by using materials with high magnetic permeability, such as soft iron or mu-metal. These materials attract magnetic field lines, redirecting them around the area that needs to be shielded (here the watch movement). Soft iron is used because it does not retain its magnetism when the magnetic field is switched off, so it does not become permanently magnetized |

They used to just put scanners in really big rooms with passive shielding but these days scanners usually have a smaller outer secondary coil that runs out of phase with the larger inner coil to actively shield the room and beyond. |

Correct, the newest version has a completely different case and no longer has the anti-magnetic inner case. It also houses the 3230 instead of the 3131.
