My Posts

Dear Friends, This post does not aim at being polemic, it just reflects my own feelings. (Please forgive my Frenchman English) I have owned quite a lot of watches, including PP, VC, Breguet, AP, and a dozen Rolexes and Omegas. Curiously I now find myself perfectly happy with… a Tudor ! Let me compar

Hi all, I wonder what are the sport / diving watches in gold selling for, say, less that 20k. I have in mind this Max Van Brauge and the Tudor Black Bay 58 but not many others... Which (interesting) ones am I missing ? Thanks.

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
