Platinum Polishing - No loss of metal

[Jeffreyc87]

There has been a lot of back and forth about polishing gold vs platinum.

Platinum takes more effort to polish, for the simple reason that it does not wear as other precious metals do; consequently, it doesn’t follow the same metallurgical rules.

Platinum has a “liquid” surface. Other metals lose mass over time – prongs wear thin, shanks get thinner, decorations such as Florentine or engravings wear down. All of these deterioration take a lot longer with platinum. The metal even scratches differently.

When you scratch platinum, you are actually just moving the metal aside, whereas other precious metals lose surface area.

This is what I understand. Molecules merely rearrange.

I've read about this.

Pretty amazing

so what you are basically saying is if everyone buys Pt, then the no polish army will stop their never polish campaign? Sweet.

Didn't mean to imply that.......

I want one but it isn't feasible now in my current life situation.

But, I just think it is a really unique aspect of the metal itself.

I think it would be real cool to own Rolex PT in terms of a YM with blue, rhodium dial and solid platinum bezel.

The YMs are very very pretty in real life and it gives you the opportunity to own the metal but in a more reasonable model.

That seems to be the line of thinking yes.

I think when platinum gets all scratched up it looks beautiful and takes on a very cool patina. I don't own a platinum watch, but I do have my wedding band, which shows a lovely patina now

[elcompa]

And that's what makes platinum so damn cool.

[airpeace]

Nickel and palladium are the same. The whole family are gummy metals.

Nickel isnt a pgm. https://en.m.wikipedia.org/wiki/Platinum_group

Also msi makes a pretty nice gaming laptop.

Alchemy aside, Pt group is Ni, Pd, and Pt. Their chemistry and properties are the same. Read the table vertically.

Yet when we polish a platinum watch there is still a metallic residue on our polishing wheels, just like with any other watch.

That adds up

Not worth the hassle, try getting a micron or two of gold or platinum from a lot of dust and polishing paste, not gonna happen.

Oh and next time state the source of your post, you copied something from a website.

Yes. Thanks for including the source. Apologies but Jurgen is a very good friend of mine. We met in Germany when we were young and I do not think he would mind me paraphrasing from his article.

Actually, I wound up marrying his younger sister...Paddie (family named her after palladium).

If your opinion is different than his then I guess we will have to agree to disagree.

I am not aware of your credentials but Jurg (his nickname from his closest friends) and his experience I am aware of.

Hope this clarifies.

If you keep reading the article, it goes on to say "It’s also good practice to frequently change emery papers and dress buffing wheels, as well as to recharge polishing buffs after each dressing. When polishing, you are actually removing metal, and some of that metal will adhere to the felts, buffs, and brushes. "

Be careful polishing any metal watches. I am not part of the "never polish army" but regardless of metal, when polishing some metal is removed.

Exactly.

It's high density and it being oddly malleable makes it hard to remove metal and get the desired finishing. But metal is always removed during polishing.
If I need to polish one I'll properly clean my polishing wheels and show before and after pictures, I bet no one will ever question this again after that...

Every watchmaker I've spoken to seems to agree on this yet this internet myth seems to perpetuate lol......what's true is it's extremely difficult to polish platinum and it takes much more labor to do it. You will lose metal when you polish the hell out of it....just takes much more effort and far longer than say stainless/gold.

I’ve got a platinum wedding band. I’ve never had it shined up.
