The world's leading watch manufacturers gather in Geneva for the Watches and Wonders exhibition. 54 major brands - including Rolex, Patek Philippe, Cartier Chopard, Hermès and Chanel - will be presenting their new products until Monday April 15. "We've seen our first downturn in February, but this is by no means yet a trend. Some markets are still doing very well, such as the United States and the United Arab Emirates," says Yves Bugmann, chairman of the Swiss Watchmaking Federation. IMAGES AND SOUNDBITES
