The Unico 2 caliber was designed to equip smaller chronographs and also open the world of Hublot to new enthusiasts. It retains the unique design of its former version with a double coupling system visible from the dial side as well as a 72-hour power reserve. But thanks to various technical optimizations, including the introduction of a new, flatter automatic winding system, it has been reduced by 1.3 mm in thickness. As a master of fusion and an alchemist of precious metals, Hublot has developed a new gold color with a warmer shade than the traditional 5N 18K gold. Containing mainly platinum, this exclusive King Gold alloy perfectly lends itself to all elements of polishing and satin finishing. Hublot watches blend the most unexpected materials like high-tech ceramic, rubber and carbon.
