World's most expensive watch sold at auction
The world's most expensive watch has sold at auction in Geneva for 20.6m Swiss francs (£13.4m).
Made from 24 carat gold and weighing half a kilogramme - the Graves Supercomplication was made for an American financier in the Thirties.
It took eight years for the Swiss watchmaker - Patek Philippe - to complete.
Tim Allman has more.
