Interesting information. I suppose the ratio between both same models in gold and platinum will vary from one brand to another thanks to different internal alloys

Just checked my periodic table and the platinum has a density of 21.45 vs 19.28 for gold (yellow of course).

In order to compare with other materials:

16.6 for tantalum
12 for palladium
4.54 for titanium
between 7.5 and 8.1 for steel
between 8.4 and 9.2 for bronze
2.25 for carbon

Easy to understand why some watches make your arm stronger than other ones ;-)

Best wishes

Trivial though weighty information...

... Awhile ago, I got curious about weights of watches, so I bought a small scale. I was swapping straps between these two Chopards yesterday and figured I'd weigh them, just to see the difference, while I had them in their rare strapless state. The L.U.C...  

Interesting how much more dense platinum is...

So an ounce (standard unit of measure for commodity value) is actually smaller volume wise... Thanks for this little bit of trivia!

Good and....

interesting information! Thanks for the effort! Cheers, Filip

Different purity, however....likely 18K versus .950 PT

No message body

Might be more...

since its a more expensive metal Choaprd might have chosen to mill out more on the inner side of the case. Magnus

Is the dial on the white gold salmon or brass?

love this salmon dial

and the movement---especially the micro-rotor! i don't think this model is still in production,sigh! Thanks for sharing it.

Wowww!!

A killer combination of salmon and micro rotor.. I am really liking it. Only the date is a niggle, but hey, it\'s difficult to ask perfection Thanks for sharing! All the best, Alex

I think in the case of such classy watch

no date would complete an already amazing piece. I am really blown by the dial, case shape and movement. A great piece for any collection. Alex

Interesting comparison [nt]
