Dear all, Five years ago, it was announced that AP and Swatch developed a new non-magnetic hairspring. See, for example, here . Do you know if it is used in current calibers, in particular in the 4302 ? (A simple MacBook generates field of 80 000 A/m at t...  

I don't know about the use of this hairspring material. But I would think your statement of a macbook producing 80.000 A/m (or 1.000 Gauss) at the wrist cannot be true. I wear many different watches, also vintage, also with a glass caseback. And I work on... 

I performed the measurement myself with a professional gauss-meter, so I can assure you that the field is 1000 gauss at the level of the keyboard. It is however true that It is lower at the place the watch is worn. It would be as I say if one was putting ... 

Just slide a metal object (a spoon or a knife) on your Mac close to the speakers, you will be surprised !

My own measurement was not so dramatic but we stil agree on the order of magnitude. And we all agree, I think, that magnetism resistance is nowadays way more relevant than (extreme) water resistance. We all know the water resistance of our watches, I thin...

Demagnetizing is welcome when the watch is magnetized. For sure ! But remember that it basically work by first... magnetizing the watch (and then slowly cycling to smaller fields, therefore removing the memory effect) ! So, in principle, it is still bette...
