Yellow gold watches
The ‘jewellery’ gold used in Vacheron Constantin yellow gold watches is associated with an alloy in order to increase its rigidity and correct its colour. Since 24-carat gold is a virtually pure or fine gold that is too malleable to be used in watchmaking. That’s why Vacheron Constantin uses 3N yellow gold composed of 75% gold, 12.5% silver and 12.5% copper. Vacheron Constantin works alongside its suppliers and refiners in seeking to improve the controls performed throughout the supply chain by means of ongoing close cooperation with the Responsible Jewellery Council.
