HYT launches the S1 Titanium ‘Japan Limited Edition’, an edition of eight pieces marking the pre-launch of the S1 permanent collection, a radical new series of hydromechanical sports watches. This new watch is a striking first in a forthcoming series of sports watches made by HYT, the inventors of the hydromechanical wristwatch. This is also the first S1 to be open-worked.

The S1 Titanium ‘Japan Limited Edition’ confidently presents itself with an ergonomic 45 mm titanium case defined by its chiseled looks and is softened by a subtle satin finish. The hydromechanical caliber 501-CM takes center stage on the new S1's open-worked dial. It mixes and matches an introverted, softly shimmering silver colorway with edgy, angular lines and an outrageously exuberant high-tech mechanical movement on display for all to see. The watch is the monochromatic forerunner of a sports watch collection on the horizon, and it tells of HYT’s strong ambitions for the future. It’s also a statement. The new timepiece shows HYT’s enduring capabilities to combine fine craftsmanship, technological innovations, and progressive design while ensuring optimum wrist comfort.

The open-worked design allows a clear view of the watch’s finely finished “engine” and emphasizes the S1’s sporty, tuned, lightweight nature. As expected from an HYT creation, the attention to detail is phenomenal. The flange's miniature honeycomb structure, which also holds the Arabic numerals that mark the hours, is fully in theme with the lightweight sports theme.

An excellent example of technical uniqueness, boundary-pushing design, and a joy to wear. It combines a well-proportioned and ergonomically shaped case and a thought-through strap design. The lightweight silver and black-coated titanium case measures 45.30 × 17.20 mm and has a case length of 46.30 mm. The case, matched to an angularly positioned strap, ensures a stable and comfortable position on almost any wrist. And speaking of straps, the S1 Titanium ‘Japan Limited Edition’ comes with a light gray Velcro strap with a loop buckle and a pin buckle-equipped black rubber strap. Both blend in perfectly with the lines of the case and offer a seamlessly integrated, streamlined look. By the way, the ingenious quick-release, strap-change system makes changing between them a matter of seconds.

With its two small bellows and finely sandblasted and satin-finished movement parts, the movement's unique looks might be disruptive even after 12 years —the first hydromechanical HYT creation burst onto the watch scene in 2012. However, the caliber 501-CM’s performance inspires confidence. Years of development and fine-tuning have resulted in a highly reliable movement that has no equal. The caliber 501-CM combines traditional and contemporary qualities most fascinatingly.

The movement’s traditional characteristics include a Haute Horlogerie level finishing of all the individual parts and a mainspring you need to wind by turning the titanium crown between 2 and 3 o’clock. When you do, it will move the central minutes hand, the small seconds in a sub dial between 9 and 10 o’clock, and the small hand of the power reserve indicator, which is placed in line with the crown. The hands do their respective jobs dressed in dark gray and white. With their distinctly contemporary look, the satin-finished hands received a touch of white SuperLumiNova for optimum readability in dark conditions.

The mechanical movement also transfers energy to animate the display of retrograde fluidic hours. Although the ground-breaking, 352-part caliber with a beat rate of 28,000 vibrations per hour (4Hz) and a power reserve of 72 hours is a fully evolved, fool-proof movement, it’s also unique. Its exotic looks never cease to amaze, and so does the technology. For instance, the prominently placed pair of small bellows are made of an alloy with walls just one-quarter the thickness of a human hair that is 10,000 times more watertight than a traditional dive watch. The uniqueness of the two bellows is only rivaled by the very fine glass capillary tube connecting them. In the S1 Titanium ‘Japan Limited Edition’ black fluid marks the hours and perfectly matches the watch’s monochromatic attire.

The open-worked S1 Titanium ‘Japan Limited Edition’ is a one-of-a-kind sports watch with an open-worked design that reveals its hydromechanical ingenuity and power and accentuates its intricate design. The first S1 Titanium of its kind is a limited edition. Still, the upcoming S1 collection will share all the elements that make this debut watch stand out: ground-breaking watchmaking fueled by creative inventions and uncompromising innovation that’s astonishingly comfortable on the wrist.

The new HYT S1 Titanium 'Japan Edition’ is available in a highly exclusive limited edition of only 8 pieces.
