The 2003 Basel international watch and jewelry fair (April 2-10) will unveil a "new brand image," including a new logo, capping three years of show expansion, improvements, and changes, says new show manager Monica Guarnaccia. Those changes include revamping of the watch and jewelry halls; a "one show, two locations" concept (Basel and Zurich), effective this year; the revamped Basel Forum; a new research project to gather data on the global watch and jewelry luxury market; and improvements in visitor services. Guarnaccia, who took over as show director on Jan. 10, continues as marketing and communications manager of the Basel Fair. Martin Fergusson is Basel show director of watch brands, and Sylvie Sengelin is show director of jewelry and related brands.
