However, for a gold Daytona, the value is in the condition of its case. You can always find a tritium dial, but you cannot unpolish a case. Only the early porcelain or inverted 6 dials have a superior value on their own.
Rhodinated wg is just as bright as platinum. However, the rhodium plating may wear of, like gold plaque. I am not sure, though, when they stopped rhodium plating. I thought it was long before the 5205. Personally, I prefer pure white gold because of its warm shine.
I have no intention whatsoever to pretend anything improper. This is my kit watch. Except for a dial and a caseback it is genuine Panerai. Everything can be brought back to stock. No animals or children were harmed. And I have a hell of a time with it! Cheers!
