Patek Philippe Chairman Thierry Stern gestures as he speaks during a Reuters interview at the Baselworld fair in Basel March 26, 2014. The bulk of the $50-billion Swiss watch market has for years been aimed at wealthy men drawn to high-tech, gadget-loaded timepieces they can wear as status symbols. But, faced with only single digit growth prospects, top brands are looking to the other 50 percent of the population for inspiration. A trend for bulkier watches, and a boom in jewellery sales have lifted levels of interest, which has also been driven by a growing middle-class female customer base in China. Currently, only about a third of Patek's watches end up on women's wrists, but Stern wants to increase that share to 40 percent. To match story WATCHES-LADIES/ Picture taken on March 26, 2014.
