Known for blurring the lines, HYT the HydroMechanical Horologists have once again defied the limits of what is possible. As if mastering telling time with fluids wasn't already impressive enough, the new HYT H3 is even a more complex part of the HYT evolution and their continued pursuit to push the limits of horology. The H3 is a massive timepiece in terms of size but what's inside is even greater than the sum of its case size measuring 62 x 41 mm. Its movement —like out of sci-fi movie speaks for itself. HYT and its partners at APRP —Audemars Piguet Renaud & Papi— have succeeded in creating a timepiece with a highly complex architecture. One of the main challenges was the machining of the case and the special curved sapphire crystal. When it came to the movement, one of the most delicate steps in creating the H3 involved recovering the energy provided in the retrograde movement, which then powered the semi-instantaneous rotation of the watch's dial with use of the fluid going back and delivering the necessary energy.
