The gold to platinum ratio is 0.94 today; does anyone think it will go over 1? Makes you wonder about paying a premium for platinum watches.
...is that platinum remains much more scarce than gold so should ultimately be more valuable
difficulty of making platinum cases, platinum being rather soft the tools used for milling a case need to be changed with each case, which is not the case () with gold
Isn't gold much softer than platinum . Being harder is the reason tooling needs to be changed after milling just one case (wow). BR, Dan
interesting part! platinum sticks!
here's an extract from my article on VC platinum watches: The Platinum Connection on the difficulty of making platinum cases:
It takes about three times longer to make a case in platinum than in gold. As platinum is an extremely resistant metal, slower tool speeds and lower pressures are required to minimize friction and tool wear. The metal heats easily and can subsequently deform (rendering a rather inelegant “orange peel” effect) and can be only worked by experienced artisans. To make the case, a platinum sheet is rolled to the required thickness and stamped out to form shaped blanks. These blanks are then machined into final shape by computer controlled lathes using up to 15 different tools to attain the final result. The case needs then to be hand polished: an intricate process that involves eliminating all the machining marks by applying successively finer grades of abrasive paste to obtain the special luster which makes platinum so desirable.
