Platinum easiest to scratch than steel?

 
 By: Watch_kha_wen : August 6th, 2018-10:12
I don’t how I did that but I scratched my 5056p buckle. I did not even hit anything with it but as I wore it with short sleeves I probably did that by leaving my arm on the desk or something. Anyway I am sad...!! Kev ...  

Scratch on the buckle is like sand in the desert,

Platinum, like gold....

it's much "softer" than stainless steel and it scratches real..easy

Platinum has a higher tensile strength than gold..

...but is still soft. So gold, with it's softness and lower tensile strength will both scratch and wear easily. But platinum -- soft but with higher tensile strength -- will wear differently. When you scratch platinum, the scratch isn't normally produced ... 

Very interesting!

Thanks for sharing !

It was not my intention to....

 
 By: sergio : August 6th, 2018-12:58
imply that platinum, gold and chewing gum foil, were...one and the same. Only that platinum and gold are softer than stainless steel and get scratched much more easily. I will, however cherish the new found knowledge. After all, you live and learn, isn't ... 

Very useful info, thanks vm

Perfectly explained too! Considering pretty much 99.99% of watches here are SS, gold, or PT, I am surprised most of us know so little about their individual characteristics (myself included, obviously!!)

Mo's scale of hardness is interesting

 
 By: daveyboyz1978 : August 10th, 2018-03:29
Steel=4, White gold=4, Platinum=3.5 and yellow gold=2.5. Platinum is very hard therefore, not quite as hard as steel but much harder than yellow gold. White gold is hard because of the alloy and White gold and Platinum are often Rhodium plated... Rhodium=... 

I'll just say that from a mineralogy viewpoint, a Mohs scale hardness of 3.5 or 4 is not considered hard, although you are of course correct, platinum is harder than gold...

...and that, in and of itself, makes it more resistant than gold to wear and scratches. But it's when you consider the greater tensile strength of platinum that you see why it's more difficult to polish than gold, and also wears better. The higher tensile...

I’m sure the AP got some scratches as it brushed against bracelets and other jewelry. Still, I had a great time. The more you wear your watch, the more you get to enjoy it!

Haha

I am actually thinking about it ! Kev

Now that your watch has a battle scar, you should feel...

PROUD ! PuristS are proud of you ! Enjoy the watch often.

I guess all precious metals are softer than steel.

Can feel the pain of scratching the watch. But it is still better than just keeping the watch in the vault. The only thing we can do is to be as careful as possible, and avoiding some high risk actions. Best, Henry
