Avant-garde watchmaker HYT introduced the H1 hydro-mechanical timepiece back in 2012. The watch arrived to much acclaim, and the intervening years have seen a steady succession of functional wrist wear that bears the same innovative design.

The latest in the hydro-mechanical line from HYT is a limited production watch; very limited, actually, as there will be only five available for purchase. The piece is an homage to early HYT champion Mr. Porter, and the watch is called the H1.0 x Mr. Porter.

The watch’s remarkable design is matched by its utilitarian appeal, which is evident in its looks as well as its materials—stainless, titanium, and black rubber. A bit of right-brain appeal sneaks in with dashes of red, and luminous measures and minute hand.

The H1.0 x Mr. Porter is priced at $58K.
