A Swiss watchmaker is hoping to raise a stink with an expensive timepiece that eschews the trade's standard gold, diamond or titanium fittings for a more earthy substance - dinosaur dung. Vesenaz, Switzerland-based company Artya says the watch set in fossilized feces will sell for 12,000 ($11,290) and comes with a strap made with skin from an American cane toad. Designer Yvan Arpa said Monday the coprolite came from a plant-eater that died about 100 million years ago in what is now the US.
