Can polishing magnetize a watch?

Yep made of copper and tin, two of the least magnetic metals 📖

"If complete and utter chaos was lightning, then he'd be the sort to stand on a hilltop in a thunderstorm wearing wet copper armour and shouting 'All gods are bastards!" Colour of magic

I know I am pulling a fast one, but it's Pratchett. I just had to..

Mm thinking re @dialstaic experiment with the misses. Testing the watch later today will probably show that it contains a negative charge. The problem is not if outside of the case has a charge but if the inside is affected by it. I am refering to my first question does the watch contain a soft iron inner case?

Again this "gut science" and not empirical proof.

So let me refer to the thinking behind a "man is not lost". And the development of the standards that led to the mark 11 being designed. In short a watch that can operate in a highly magnetic environment.

Also It makes me think about Faraday cages. So to my understanding of this physical magnification it's charge is on the outside and the content is safe. Ie you get a shock when trying to get in the car. However lightning can strike the car and the occupants are safe. Though they might be a little shock up.

So is it sufficient to earth a magnified watch or is to late as the damage has already been done.

Again thanx for all comedy but science will prevail.

Now all I need to do is wear my bronze watch under my wooden sweater sleeve all day, and I can check for the presence of a charge tonight.

I thought that "wooden sweater" quote was just a typo, but these things really exist! 😲

The image of an OmegaForum member wearing such a thing while trying to "magnetise" their bronze watch with an electrostatic charge is fabulous.
Keep going sir.

I never knew you could magnatize bronze. I always thought it was anti-magnetic. Or am I yet again missing something important.

No, you're completely correct as far as I know. Bronze is non-magnetic. I've read that in the late 19th century, they even made parts of the movement's pallet fork out of bronze in an attempt to counter the effects of magnetic fields. I was simply asking if there might be some other property of bronze that might cause it to shield a movement from magnetic fields less than a SS case would.

In particular, I was interested to learn that - at least in theory - you could build up an electrostatic charge on the surface of bronze more easily than you could on steel. But even if that is indeed the case, I have no idea if that would have any effect on the movement.

Quite right. I just wanted to check if I can indeed get a measurable charge on the surface. If not, then there's no point in asking the follow-up question (i.e. if such a charge could potentially affect the movement). I checked, and there's no soft iron inner case to shield it from magnetism. It's just a bronze case with a movement slapped into it. Very interesting article on the mk11 development, by the way. Thanks!

I reconsidered the wooden sweater idea once I noticed that wood is too close to bronze in the triboelectric series.

Ok another observation. The duh of course moment for the nerd mathematician and gut science geek in me.

You have not shelled the connection of your cable ergo you blew up your speaker. Or worse. You stood infront of the microwave with door open whilst it was on.

See practical section here for geekery.

https://en.m.wikipedia.org/wiki/Electromagnetic_shielding

It makes sense now why the white dials never gained Navigator status as the dials were made of out copper not iron. So the Faraday cage is not complete it's got a massive hole in it. See microwave bit in wiki.

At first i had hard time getting my head round the magnetic shield and separating it for electric shield but both concepts are similar ie a cable has a magnetic shield and insulating layer.

Please Mr physics help us mortal maths folk understand. We are simple folk wanting simple and beautiful expressions. Have I drawn correct conclusion from everyday items.

"Undeterred by ridicule, I bravely scienced on because science - like love - is a verb. Or maybe it's a noun. This isn't my first language and I can never tell those two apart.

I tested the device by combing my wife's hair with a plastic comb (and a hidden agenda). It works! Now all I need to do is wear my bronze watch under my wooden sweater sleeve all day, and I can check for the presence of a charge tonight."

And all these years I thought wood was an insulator of electric charges. Where do you buy wooden sweaters? 😉
Remain undeterred. Maybe through your efforts we will all learn something. 👍

@dialstatic what was the conclusions to the wooden sweater and how did the watch test on the magnegaget?

@Trev @dsio - please, please, please make dialstatic's custom avatar message "bronze watch and wooden sweater wearer" or something along these lines.

Leave it to a guy who has a screen name like his to test for static charge.

I couldn't get a reading. I rubbed my bronze watch feverishly on everything I could find around the house that's made of a material above bronze in the triboelectric series. My wife drew the line at me rubbing my watch on her hair, so I used the cat instead (fortunately, he's a nihilist and cares about nothing) but to no avail.

In theory, there should be an exchange of electrons and a resulting charge but if there is, it's so small that it doesn't register on my crude device. I'll borrow an electrostatic voltmeter at my university sometime soon to check. So in any case, there doesn't seem to be a substantial charge, so my hypothesis that it could affect the movement seems less plausible now.

Now the question becomes, how does one was a wooden sweater?

is there a special wood mix?

Do you varnish it and just hose it down?

Will it shrink or stretch in the wash?

Well, being from The Netherlands, I'm accustomed to wearing a pair of these:

These make nice souvenirs because they fit in suitcases. Because wooden sweaters don't, they're not as widely known as a staple of traditional Dutch attire.

In find even today that the publishing of work done is the way to go. It is after all the accountability, for time taken, work done, conclusions drawn and ultimately cost. So often forgotten by management and directors. Who only are interested in the bottom line. The good ones are those who understand why it wasn't done at tenth of the price and delivered last week instead of the day after tomorrow.

@dialstatic Like your "träskor" keep up the hard work.

How did we get this far without a single photo of the famous electrostatic bronze? I was going to do a @meganfox17 style detective job and list all the candidates but only go as far as the Aevig Valkyr bronze when I was seriously distracted by their Huldra vintage C-Case styled diver in blue.
http://aevig.com/huldra/

How come a little dutch company can produce such a nicely styled watch like this for a few hundred quid whereas Omega's idea of a great diver is the Planet Ocean 600 M Deep Black at 10K?

The build quality and attention to detail of this Omega is really excellent but it's just so OTT. Apparently that rubber thingy came about because the designer wanted an orange ceramic insert in the bezel, but it kept coming out redish, so they switched to rubber and the rest is what you see. Technically top, optically flop.
Oops, I think that was a thread hijack. So back on topic. Which one of these was it?
