Here is a video about how hand winding might damage your watch: kzfaq.info/get/bejne/f5l5gtxqtr6reKs.html

Great videos as always. What is your wrist size buddy?

I got concerned about this that I got the Citizen 'Ray Mears' Promaster for its anti-magnetic properties ( digital display-only watches do the same job but they're not me). I now keep my watches away from potential objects, although one bonus of my Certina diver is the hairspring ( apart from the basic ISO compliancy of anti-magnetism). Perhaps one day all watches will be made with more anti-magnetic movements (apart from Omega, Rolex, etc.)?

Thanks! Btw can you imagine demagnetizing part of the mechanism?

The question is, though, how close does a watch have to get to the type of magnet that is common in daily life (e.g. in a phone of headphones) to get magnetised? In the experiment you showed, the watch was affected by the magnet being near it, but was it actually magnetised? The trace on the timegrapher seemed to change again when the magnet was taken away. My own experience is that my vintage watches rarely get magnetised, although it happens sometimes. I'm generally casreful to keep watches a centimeter or three away from (e.g) my phone, but I don't obsess over it (and I use my phone while wearing watches).

Good video, thanks for sharing! 👍

Just buy a decent demagnetiser some can be rather expensive I us a Etic useful for damaging other metallic items

Not my Metas rated 15,000 gauss piece

Magnetism doesnt do any damage at all. The movement simply get magnetized... 😂

This idiot rips the whole case off and stick a permanent magnet to the spring. Misled us how inaccurate the watch movement is. With the watchcase, the movement will need to be magnetized by a very strong magnet for it to be affected. Everyday speaker magnets, phone won't harm. Even non ferromagnetic case will provide a decent shielding. With nowadays steel case watches, magnets won't harm anything at all
