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 a macbook day in day out. And have never noticed any effects due to magnetization. None of my watches even approach a magnetic rating of 80.000 A/m. I don't know how much a macbook does produce, but in practise it is not a problem for mechanical watches.
AP and the Nivachron hairspring
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...
Well
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 ...
BTW
Just slide a metal object (a spoon or a knife) on your Mac close to the speakers, you will be surprised !
Yes and no...
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...
pp website say - avoid exposing your mechanical watch to magnetic fields because they can alter its rate or even cause it to stop running,
and vc website say-BIG CONSEQUENCES When it comes to mechanical watches – both manual and self-winding – are more sensitive to magnetic fields. In rare cases, a magnetization effect occurs on certain sensitive steel components of the movement, including t...
