In this first of a two-part series, we go beyond stainless steel and gold to look at emerging metals used in watch cases and bands.
Platinum. Popular with elite, special-edition watches, platinum is highly resistant to corrosion and tarnish, and won't chip. It is also hard to scratch, durable, pliable, and rare–30 times rarer than gold, for instance.
PVD. PVD stands for physical vapor deposition and refers to the process of binding a usually black and permanent layer of compounds to metal. This gives any watch a striking look which has become sought-after in recent years. Almost every Swiss watchmaker now offers a PVD-based model.
Palladium. A platinum deritiative, it is whiter, cheaper, and much lighter than it's cousin. Palladium is often used as a substitute for nickel in white gold. It's lightness and non-allergen characteristics make it an increasingly popular choice among watchmakers.
