A Lange Pour le Merite Tourbillon in white gold just hammered for CHF338,500 at the Antiquorum Geneva sale on Sunday. That’s equivalent to about USD358,000, EUR276,500 or SGD447,000. 

Only 19 Tourbillon Pour le Merite were made in white gold, with another 130 in yellow and rose gold (most were yellow), 50 in platinum and one in steel. This is a record for the timepiece, which has seen steadily rising values at auction, as evidenced by recent sales of platinum and yellow gold specimens.
