Guess Watches will team with smart watch developer Martian Watches to develop “interactive, voice-command wrist accessories,” the companies said Wednesday. The companies envision marketing “smart wearables” combining fashion and technology that will be Guess-branded and bearing the label “powered by Martian,” they said. They expect to announce specific products by early 2015, they said. A Martian Watches engineering executive predicted in the spring that “killer apps” ultimately will determine whether smart watches succeed or fail, but conceded then that “there’s no such candidate right now” (CD March 7 p15).
