I have a question about white gold cases. Although both my Panerai Radiomir Zerograph and GP SF Foudroyanteare are made of white gold, the color looks different. The Radiomir has a more yellow shine whereas the GP has a more steel shine. I'll try to make some pics to show the difference. As I understand white gold is a combination of gold with something else (.....obviously...) but can someone tell me the differences ? Is there a difference between white gold and grey gold (or gris) ?
Thanking you in advance,
best regards,
Mark
