Food for thought about gold vs platinum Rolex pricing, from Coronet:
“…estimates based on total watch weight and shared components show that the white-gold Day-Date contains about 5.3 troy ounces of pure gold. In today’s market, that is worth roughly $26,500. The platinum model contains about seven ounces of platinum, valued near $14,700.
That means buyers of the white-gold Day-Date pay roughly $26,500 for metal and about $25,100 for the rest of the watch. To compare, the platinum version, which looks nearly identical, charges $14,700 in metal and $54,100 for the watch.”
