According to Panerai, the key to this characteristic is the composition of the alloy, which is 75% gold, 24% copper (whose presence you'd expect due to the material's deep red coloration), but also a small amount link of platinum (0.4%). It's this hint of platinum matched with a high concentration of copper – a ratio fine-tuned at Panerai's Laboratorio di Idee – that accounts for what Panerai describes as its "unique tone and link an extreme degree link of mechanical and oxidation resistance."
