TM, so your brand of PC is approved for WIS
Likewise, I will headache if too long on the mobile....so now use a cable-mouthpiece. Likely due to the RF (microwave). Can't prove it though.
Typically when you dialing out from your mobile, the power of the RF is the highest to ensure connection. What make it worse is the distance between you and the station. The nearer you are to the station, the lesser power of RF will be transmitted....ie. your phone battery also last longer. The mobilephone will adjust the power automatically to ensure good connection.
You are right though you are the early adopter, you still have not encountered issues with your watch. The reason is simple.The magnetic components (the earpiece and the mic) are quite a distance from your watch (wrist). The only time when the distance could be near is when many localised their wallets, keys and watches at a single location and extremely close to each other. That where the chance of watch being magnetised is the highest!
Indeed it is good you brought up EMI & RFI, they are magnetic waves and not magnetic field.
As one of the forummers (zephyr49) also mentioned, he works in the Air Traffic Control Centre, and his watches are fine. No doubt about it, as communication machines generate EMI/RFI waves....but if he works in a MRI room, that will be different story.
An antimagnetic soft iron cage will not be able to defend itself if too near to the magnetic field (source)... even the IWC test also showed possible "hotspots".
Great, the Toshiba has the speakers at the hinge areas.... now the question is where is your harddisk
