Video: How Harry Winston’s New Opus XIII Works Written byMark BernardoMay 21, 2013 As per usual, Harry Winston generated a fair amount of buzz at the 2013 Baselworld watch fair with the latest timepiece in its haute-de-gamme Opus collection. This year’s piece, the Opus XIII, turned heads with its 242 functional rubies and unconventional time indication by means of tiny, pivoting markers around the dial. Developed in cooperation with watchmaker Ludovic Ballouard, who helped develop F.P. Journe’s Grand Sonnerie, the Opus XIII has 11 triangular hour hands, which peek out from a dome in the dial’s center and retract at the end of each hour, and 59 little minute markers (each five-minute marker is red-tipped), which pivot toward the center of the dial as a new minute begins. At the end of the hour, all 59 minute markers pivot back to their original position at once, in a dynamic, wave-like motion, and the process begins again. To see the watch, and its ultra-complicated twin-barrel movement, in action, click below the photo to see Harry Winston’s official Opus XIII video.
