When Jay-Z gives you a shout-out (see “Otis”), your profile shoots way up. So it goes with watchmaker Hublot, who plan to release the Hublot King Power Unico GMT Watch. Available in either gold or black ceramic, this 48mm heavyweight gives you the time in 24 different time zones. Four rotating GMT discs on the watch face rotate in sync. As they do, the red markers line up with corresponding cities on the ceramic bezel. Great for those who travel a lot. Also good for those who work in cubicle farms and wonder about the time in their favorite vacation spot. Dwayne Wade just signed on as a spokesperson, so you’ll find yourself in great company with this on your wrist. Debuts in Geneva in January.
