There's also a strong branding presence of Swiss products in UAE and China (including some brands you'd never hear of in Switzerland itself), there seems to be a very strong association of "Swiss Made" with luxury product. I've even seen opticians advertising "Swiss Glass"(?) in Hong Kong. Thinking back to a talk by the founder of Virtu, I wouldn't be surprised if the middle and far east are key markets for this type of product.
