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 better to avoid.

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 think we should also know the magnetic resistance

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

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 the watch on the keyboard. Best.

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 the level of he wrist) Thanks !

Dear friends, I have recently reported in the "main" forum that the magnetic field generated by a MacBook Pro laptop is around 1000 Gauss (I have used a professional gauss-meter). Is this safe with a watch using the UN-118 caliber ? I know that the hairspring is non-magnetic but the rest of the move

Dear friends, You might have noticed that MacBook Pro laptops generate impressive magnetic fields. I have just used a professional gauss-meter to figure out the real value. Basically, there are 2 "hot spots" (unfortunately on the left side of the computer, just were your watch is situated when you u

Dear friends, More than a decade ago the pulsomax escapement was launched in the regulator (5235). It also appeared in some "advanced research" pieces. But it seems that the new travel time annual calendar launched this year and based on the same caliber (31-260) does not use it. Do you know why ? I

You might consider not being rude and arrogant. If Breguet posts incorrect pics on their own official website this 100% stupid. There is NO DOUBT the inner angles are NOT present on their film. If official releases from the brand cannot be trusted... If questions cannot be debated on a forum, I don'
