Alexander Zverev marked his 2026 Grand Slam triumph with a remarkable $280,000 Jacob & Co. The World Is Yours Dual Time Zone Tourbillon on his wrist. Limited to just 199 pieces, the timepiece combines an intricate three-dimensional world map dial with an 18K rose gold case, a flying tourbillon, and a dual-time mechanism that allows two time zones to be read simultaneously. A major victory, a rare timepiece, and a watch that is every bit as distinctive as the moment itself. JacobAndCo #JacobAndCo
