The reddish tone of the gold comes from copper. This fine gold is soft and corrosion-resistant and produces a precious metal that is high-grade, exquisite and highly popular in watchmaking. The colour nuances, depending on the copper content, range from soft rose to powerful dark red. At Lange, pink gold is used with 205 parts copper to 45 parts silver. This makes for a purity of 18 carats (750 ppt).
Copper imparts gold with a reddish hue and transforms pure gold into a metal alloy that is very popular for watch cases.
Platinum means “little silver”, but the material is more precious than gold. It is eminently suited for crafting jewellery and for watchmaking.
Honey gold: harder than other gold alloys, unique in colour and exclusive to Lange watches.
