Let's say you have a cheap-ish watch that runs -8s/day. Since magnets almost always speed the watch up a bit, would it be 'wise' to attempt a quick & dirty speed-up regulation with a small neodymium fridge magnet? You could bring it progressively closer to the watch for a couple seconds, measuring the effect each time using a fancy timegrapher or a smartphone app like WildSpectra. Better not to crack open the caseback if you don't have to.

As many have said, 2 years ago, this is a very helpful video. Thanks Marc. What might have been even more useful is if you explained HOW you used the unit. But for those who watch carefully, it is evident. It's important to note that when magnetizing, Marc placed the watch inside the "machine", then pushed the button and held it down for a few seconds...then RELEASED the button while the watch was still in the machine. This is important. When demagnetizing, do not release the button while the watch is inside the machine. Release the button only after the watch has been pulled out of , and drawn away from the machine, slowly.

But in opposition a winder keeps lubricants from coagulating, ie less effective. Many thanks.

It seems to me if magnetism caused the spring to contract it would be pushing less. It would be contacted by the magnetism but that force world not be helping the spring unwind, it would be resisting the unwinding. Perhaps the magnetism works in opposition and forces the spring a bit out making its natural tension higher. That would be consistent with running fast. The other way is illogical. Imho

You said in a comment bellow that if we don't work in a specially electrified environment, we don't have to worry. But you also said that we have magnets in TV screens and even our laptop has magnets. ISO 6425 includes this protection up to 4800 A/m, which is not that much. I was thinking in a BALL, 80000 A/m, just to be in the safe side. I wonder if I am overreacting... Thanks in advence for your answer.

I'm a bit confused. The Rolex milgauss, a watch specifically advertised for being anti magnetic withstands a field up to 1.000 Gauss, according to the official rolex website. Omegas in-house movements such as the 8500 and 8900 found in their planet ocean's are claimed to be anti magnetic to a field up to 15.000 Gauss, and the selling point of watches is not even their magnetic resistance. Am I missing something, maybe the Rolex has a higher rating and I just couldn't find it anywhere?
