Platinum is the rarest of all the major precious metals. It is the heaviest and most dense of all precious metals. It will neither oxidize nor easily deform by itself.
When the Metre system was introduced, the standard reference for both the meter and the Kilogram were produced in a platinum-iridium alloy so as to make them as impervious as possible to chemical and physical deformation. Twenty tons of ore must be extracted at depths ranging from 3,000 to 5,000 metres underground to accumulate enough platinum to make one Rolex Day Date Ice blue watch case!
Platinum is particular heavy and resistant, it is extremely arduous to work. The Hugh specific gravity platinum makes great demands on the skill and experience of watchmakers. To ensure a fully watertight oyster case, for instance, they must adjust its parts to within one-hundredth of a millimeter!
The fabrication of a mere five watchcases in platinum results in as much wear on tools as fabricating some one hundred gold cases. Though they are milled and cut by CNC (computer numerical control machine). That is tedious to monitor the tool life and also take much work to perfect the final polishing by hand.
In short, a Rolex stainless steel Oyster Perpetual Date Just watch is selling $X, a solid yellow gold Day Date is selling 4X, and a platinum Day Date Ice-blue is selling about 9X! You can see what value is Platinum is!
