Series limited to 25 pieces.
The central part of the H3 is reserved for the time display. This features neither hands, nor satellite,
nor any other system of time-reading ever invented before. Instead, HYT has created a rotating dial
with 4 faces arranged along the time display tube. Each of these faces is graduated with 6 hours,
thereby enabling the 24 hours of the day to be displayed.
To ensure a harmonious and linear progression between the hours, HYT has developed an exclusive
movement. A complication is used to rotate the dial on itself, to display the section concerned for the
current time. The other three faces are not visible. At the end of each 6-hour period, the time display
makes a retrograde movement. During this time lapse, the dial begins a controlled rotation, enabling
the time display to jump semi-instantaneously. When the liquid's retrograde movement is engaged, the
calibre then uses the energy stored in the bellows and provides the force needed by the hour dial
To ensure the technical and stylistic cohesion of the H3, HYT has also developed a linear display for
the minutes. On the lower right-hand part of the timepiece, there is a twin articulated arm which
sweeps across a graduated rule. At its end, the retrograde mechanism instantaneously returns to its
