Anti-magnetic ?

路Typically, but not always, a watch will run fast when magnetized. It can be as small as less than a minute a day in my experience, or very fast at several minutes per day. In extreme cases I've seen the balance spring so contorted from magnetism it's stopped the watch completely.
Magnets and magnetic fields are all around us. If you handle loudspeakers with permanent magnets for example that could cause problems with the watch, but in my experience the iPad covers are a big offender, or any other device that uses small but powerful permanent magnets.
Cheers, Al
Are there any conditions where demagnetizing could harm a watch...assuming I'm using a demag designed for watches? eg, should the watch be stopped, or doesn't it matter? Would you even bother with a quartz watch?

路路Omega Qualified WatchmakerQuartz watches have a permanent magnet in them (the rotor) so demagnetizing them can cause problems. But with mechanical movements if the right demagnetized is used, it should not cause any damage. I always demagnetize the watch while its running.

路Al,
In your experience does a master coaxial AT really provide much more magnetism protection over an older AT with a silicon hairspring?
Do the watches with the Si14 marking have a silicon balance wheel as well as the hairspring?

路路Omega Qualified WatchmakerWell yes on paper it does, but in the real world I think too early to tell if it makes a difference. My gut tells me for most people it won't make much difference, but that's pure speculation.
Second question is no - if I look at the 8500 technical guide, they give a quick synopsis of the main features of the movement at the start of the guide:
"Chronometer movement (certified COSC), automatic, center seconds and semi-instantaneous calendar.
3 level Co-Axial Escapement. Free sprung balance with regulating screws. Silicon hairspring (version B)."
I've underlined how it is written there, and they specifically say the balance spring is silicon, not the wheel.

路Thank you Al!! That answers the question and helps guide me. Really appreciate it.
