Given that yellow gold is now almost 2 1/2 times the price of platinum, how is it that platinum cased watches are astronomically more expensive than yellow gold watches? Manufacturers will bleat that platinum is more difficult to machine than gold, this is a fact and I accept that it is a extra cost but when a platinum cased watch can be three or four times the cost of a gold one, I strongly suspect that manufacturers are ( and have been for some considerable time) taking the absolute piss!
