Press release: HYT H2O

Pinterest LinkedIn Tumblr +

HYT releases two limited editions of the H20, each comprising 25 numbered pieces. One is in black and uses a bright green fluid for a stealthy look; the other has a silver-colored case and deep blue liquid. Their universal design language is transparency, accenting aesthetics and technical detail simultaneously.

Iconic of the brand, time is displayed through a tube filled with two liquids, one colored and the other transparent. The release of the liquid is controlled by two bellows which pushes or releases the fluids. Upon completion of a full 12 hours cycle, the liquids restore to the original position in a retrograde action. A jumping minute hand, crown position indicator and thermal indicator are further elements of this live performance in a meticulously constructed theater of time. The H20 traces and embraces the essence of flow.
