Two’s company, three’s a dynamic crowd. In the wake of the H1 and H2, HYT  continues shaking watchmaking to its very foundations. The principle revealed by the first to models remains identical, with time being read off by means of two bellows pumping fluid into a capillary tube. But this time, HYT overturns time display codes even more by offering a 100% linear read-off. The two bellows work against each other in propelling the progression of the yellow fluid indicating the time and then sending it back to its point of departure. The central part of the watch is occupied by a rotating dial arranged alongside the fluid. Its four faces with six-hour graduations serve to read off the 24 hours in a day. The minutes are indicated by an articulated double arm sweeping across a graduated scale. Upon reaching the end of the line, the retrograde mechanism returns instantly to its starting point. In developing this stunning horological choreography, HYT certainly needed some serious backing when taking up such an array of mechanical challenges and duly called upon the inventive genius of APRP (Audemars Piguet Renaud & Papi). Clothed in anthracite PVD-coated titanium and platinum, this sculptural model is issued in a 25-piece limited edition.
