Since making its debut in 2012 with its startling and inimitable brand of horological alchemy, HYT has established itself in a niche of its own as one of the most exciting young watch brands in recent years. A dramatic melting pot of hydraulics, micro mechanicals, and vivid fluids, its collections of stunning avant-garde watchmaking are truly in a far-out world of their own.

The H2 Aviator is a truly extraordinary wristwatch which, with its unique HYT ‘fluid hours’ formula, and skeletonised mechanical heart, is as unprecedented in its aesthetics and in its time display as it is utterly fascinating in its technical complexity.

Bold and imposing in its 48.8mm construction of gunmetal PVD titanium and a mass of sapphire glass, with rubber clad crown and prominent crown guard, it is a magnificent beast. Brimming with detail and exquisitely crafted throughout, the H2 combines the highest principals of traditional watchmaking with HYT’s futuristic, convention-defying innovation.

The huge sapphire crystal with squared-off edge rises high above the bezel and covers the entire head of the watch, its glass wall effect offering a spectacular multi-level vista of the hydromechanical array within. Here, the bright yellow hour indication fluid oozes through the fine glass vein around the dial, past the luminous numerals on the black inner bezel, slowly drawn through in a retrograde twelve hour cycle, as the big steel bellows compress and then release at the point of six o’clock, when over the next five seconds the fluid tracks back to start again.

From the center, a single steel pointer, tipped with red and coated with Super-LumiNova, points to the minutes on a ring of smoked sapphire which is suspended above the movement. As it strikes the thirty-minute mark on half-past the hour, the hand jumps across space at the six, where the minute's ring is interrupted by the large titanium dome.

An HYT signature, the raised titanium dome conceals the reservoirs beneath, from which two fluids; one water-based with yellow dye, the other a denser clear oil base, emerge and retract, their incompatible viscosities preventing any seepage between the two. 

On the dial at the 3 o’clock position, a red pointer moves between three settings controlled by the crown, to facilitate time adjustment (H), winding (R) or neutral (N), and opposite at the 9, the unusual feature of a thermal indicator in blue and white.

 Providing the energy for all of this is the H2 centerpiece, the exceptional Calibre 201 hand winding movement, designed and created exclusively for HYT by the advanced horological innovations firm Renaud et Papi. A technical tour de force, it is reduced to its component form with its tiered gearing, levers and hydraulic rams laid bare and exposed. The mesmerizing beat of the large balance wheel and escapement, suspended beneath an arcing bridge animates the spectacle. To the rear, the sapphire case bottom reveals the stripped back plate and the twin barrels which between them store some 192 hours, or eight days, of energy.

At 48.8mm the HYT H2 Aviator is a stunning and dominating watch which packs enormous presence on the wrist, yet with its lightweight, short lugs and Kevlar strap making for a wrist-hugging fit, it does wear very comfortably for its size.
