HYT is a Geneva based luxury watch brand specialised in the manufacturing of Hydro-Mechanical wrist watches.

Launched in 2012, HYT H1, the brand’s debut timepiece revolutionised the horological market with the use of game changing fluid technology that unites mechanics and liquid within a wristwatch. The use of hydromechanics was a first ever in the watch industry and HYT was the winner of the 2012 Geneva Watchmaking Grand Prize, Best innovative Watch Concept (Grand Prix de l’Horlogerie de Genève). In Q1 2016 HYT opened its first proprietary stand alone boutique (Malaysia). Based in Neuchatel, HYT SA is the sister company of Preciflex and the main brand under which the patented fluid technology is marketed today.


HYT’s Hydro-mechanical Horologists have turned fantasy into reality, mixing mechanics and liquid within a wristwatch. While addicted to non-conformism, these alchemists have drawn upon the strictest codes of fine watchmaking, and shattered them.

By achieving the incredible challenge of indicating the time with water, they have not so much propelled a new UFO into the watchmaking stratosphere, as they have in fact pulverized all certainties by uniting two worlds that are supposedly diametrically opposed. Never since the water clocks of the pharaohs, have the laws of gravity been overcome to transpose this energy in a portable watch.

The Principle
Two flexible reservoirs with a capillary attached at each end. In one, a coloured liquid; in the other, a transparent one. Keeping them apart is the repulsion force of the molecules in each fluid. The hours are indicated by the coloured liquid released from a flexible reservoir compressed by a piston. These reservoirs, or bellows, are located at six o’clock and are made from a supple alloy. The first coloured liquid travels through the capillary pushing the transparent one back into its own reservoir and then returning to its original position at six o’clock in what is referred to as a retrograde manner. The two reservoirs at 06:00. While the first compresses, the second expands, and the other way round, resulting in the movement of the liquid in the capillary. As the hours go by, the coloured liquid advances. The meniscus, in the shape of a half moon, marks the separation point with the other fluid in the tube, indicating the time. At 18:00, the coloured liquid comes back to its original position, going backwards.

The secret that gets the reservoirs going? Two bellows made of a highly resistant, flexible alloy, each driven by a piston. And this is where watchmaking comes in to activate the system.

How The First Hybrid Mechanical-Fluid Watch Was Born?
In 2002, during Swiss national exhibition, Lucien Vouillamoz brought forward an idea of designing a water watch and discussed its possibility with his friends. However there was no technical solution existed to replace the gravitational energy used in clepsydras or water clocks within a wearable, water-resistant wristwatch. The utopic idea was swiftly put on hold in the absence of a technical solution.

After some years, Lucien Vouillamoz reconsidered his concept from a different angle – namely to create a fluid indicator of time, that is small and transportable and can be used in different ways, rather than a simple “water wristwatch”. This thought process led him to a completely new idea – involving using two flexible reservoirs attached to each end of the same capillary. This closed system comprised different coloured, non-miscible liquids in each reservoir. By compressing the first, its fluid is pushed into the capillary and indicates the time, while the other liquid expands in the second reservoir. The separation between the two liquids is ensured by the positive and negative polarity of the molecules in both, which would make them repel each other’s edges like two magnets. No need for a piston in the tube. The questions of energy and congestion were solved in one go. The idea behind the First Hybrid Mechanical-Fluid Watch was born.

Seeing the potential of this idea, Lucien Vouillamoz called upon his long time friend, Patrick Berdoz, a serial entrepreneur and business angel highly experienced in the realm of intellectual property and launching innovative projects. After verifying the concept and conducting due diligence with his team of engineers, the latter invested the necessary funds for the initial validations of the project and made his team of specialists available to Lucien. Together, they conducted the prior research and developed the first technical specifications, the first designs, and the preliminary registrations. The results were promising. Patrick continued to finance the entire project. Simultaneously, he contacted his friend Emmanuel Savioz. This specialist in the domain of high-tech start-ups was made responsible for the creation of HYT and raising the funds required to finance a prototype. Patrick also invited him to join him and Lucien in founding and sitting on the board of HYT and its sister company, Preciflex.

Following a year of R&D, the first prototype was created. The time was accurately indicated thanks to a rectangular capillary measuring 1.7/03mm, machined in a circle between two layers of plexiglass making up the watch glass. Created using rolling membranes, the flexible reservoirs are trapped in transparent cylinders. The force required to move the liquid is transmitted by a cam, which replaces the hour hand. The concept was demonstrated and the patents registered by Preciflex.

A key meeting with Vincent Perriard, who is crazy about watchmaking and already been involved in an attempt to use fluids – which actually won the 2008 Design Watch Prize at the prestigious Geneva Watchmaking Grand Prix.

Now the idea of a rectangular capillary machined into plexiglas became a thing of the past, and was replaced by a borosilicate glass capillary around 11 cm in length with a tiny internal diameter of just 1 mm, an independent capillary through which the time can be read. Instead of flowing from rolling membranes, the fluids now come from high- strength, ultra-flexible bellows (technology used by NASA) which act as pistons to enable the fluid to move inside the capillary.

To develop the movement for the First Hybrid Mechanical-Fluid Watch, HYT turned to Jean-François Mojon and his team at Chronode. For the liquid part, he advised Lucien Vouillamoz who pilots the reliability trials and the production, in conjunction with Helbling Technik. Meanwhile, CEO and HYT partner Vincent Perriard entrusted the design of the First Hybrid Mechanical-Fluid Watch to the Etude de Style design company, headed by Sébastien Perret.

Vincent Perriard obtained his movements from Chronode, while Preciflex, under the supervision of Lucien Vouillamoz, supplied the liquid components. The alchemy between these two unlikely worlds works perfectly. A year later, the first hybrid mechanical-fluid watch was emerged.
