SURPRISE GUEST: Rita Ora has a fan in Calvin Klein. The brand’s watch and jewelry division will host a performance by the British singer-songwriter Friday night at a special event at Dreispitzhalle, an industrial event space in Switzerland, during Baselworld 2013. Ora, who recently performed at a Calvin Klein Jeans event in London, has also appeared in a CK One jeans, underwear and fragrance campaign.

The fashion house plans to preview its rebranded watch and jewelry line — which underwent a name and logo change from ck Calvin Klein Watches & Jewelry to simply Calvin Klein Watches & Jewelry under the creative direction of Ulrich Grimm — for the first time globally.
