VC's white gold recipe

Does anyone kindly offer the recipe of Vacheron’s 18k white gold? It seems that some models, such as Malte Classic, are rhodium plated, and I would like to know what’s beneath the plating.

In general, nickel, silver, zinc, copper and palladium are common composition to make the gold whiter, and high weight of palladium allows manufactures to use white gold without plating. But, Vacheron seemed to have chosen to apply rhodium coating on some models.

Thank you.

18k white gold is composed of 75% yellow gold and 25% of an alloy giving it the white color,the 25% being made of 12.5% palladium, 6% copper and 4% silver and about 2.5% nickel then rhodium plated to give the case its chrome like sheen.

The disadvantage of rhodium plating is that it is just a plating and wears off with time consequently requireing replating.

Vacheron Consrtantin decided to forgo plating on its white gold cases and therefore increase the palladium content of its alloy to 15%.  Since January 2007 this has been implemented and progressively all white gold cases will no longer be plated unless the case is gem set.

For ladies models even though the 15% palladium alloy is used the cases will be rhodium plated in any even as to obtain a special sheen.

Thank you for the helpful information.

The chief reason of my interest is to know if the alloy contains nickel, as some people are allergic to the material in case the plating comes off.

Indeed, the latest Patrimony I saw was rather off-white compared to the other old models, and your information explains why. For me, increasing the palladium and forgoing plating is a favourable change, though it can be costly for manufacturer.

Very interesting development from VC (nt)

Hi Alex,

How about the components for the rose gold?

VC uses 2 types of rose gold
08/08/2007 - 13:37

4N: 75% yellow gold, 9% silver and 16% copper

5N (also called red gold due to its darker color): 75% yellow gold, 4.5% silver and 20.5% copper

4N or 5N for model 47400?

Thnaks Alex,

Would you know which type is used for the model 47400 Tonneau DT?

the Malte Tonneau Dual Time is 5N (nt)

Alex,

Thanks alot, this is good interesting stuff to know.

the more recent RG models are 5N, I don't know why VC has opted
