Wristwatch fetches $2.25M at auction

A unique watch that was once owned by an Italian count and race-car driver was sold for the record-breaking sum of $2.25 million US at auction on Sunday in Geneva.

Auction house Sotheby's touted the wristwatch that had belonged to Italian Count Carlo Felice Trossi as the largest single button chronograph of its kind made by watchmaker Patek Philippe.

Trossi, the former president of Scuderia Ferrari, chose the watch to help him keep time while driving race cars, speedboats and piloting planes, Sotheby's said.

The watch, estimated to have been ordered in 1932, is believed to be one of the first wristwatches worn outside a shirt cuff.
