You might wear their watches, but don't expect to be able to reach the same heights as these high-profile spokesmen. TAG Heuer recently named basketball sensation Yao Ming as one of their five global ambassadors for 2005. Meanwhile, Italian luxury watchmaker Officine Panerai has enlisted the services of South African adventurer Mike Horn to sell its timepieces. Horn, who circumnavigated the equator under his own power in 1999 and 2000, will be arriving in Hong Kong on Monday for a two-day visit with his wife, Cathy. He will be promoting a watch specially designed for his expedition to the Arctic Circle. In Hong Kong, most spokespersons for luxury watch brands seem to be showbusiness types. CitySeen wonders if there will ever be a local athlete or adventurer with a profile high enough to attract sponsors' big dollars.
