Precious metals
Gold. The traditional and most common texture in the luxury segment is gold (yellow, pink, white), but not in its pure form (due to its natural softness), but in the form of an alloy with a high/medium / below-average amount of pure metal in the composition. The most requested is 18k gold.
Palladium. A precious metal that is not subject to oxidation is rarely used for the production of cases due to its rarity and high cost—lightweight, effortlessly polished.
Platinum. Just like palladium, it is a rare and expensive precious metal. It is only used in ultra-luxury watches.
