H0 Black

HYT’s Hydromechanical 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.
The principle
Fine watch making meets fluid technology. A priori, a utopia. Brushing away all certitudes and all notions of conformism, the core concept that gave birth to the H1 is simple: 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.
There are two reservoirs at 06:00 also referred to as bellows. They are made of a highly resistant, flexible alloy. Watchmaking is used to activate the system via a piston that drives the bellow on the left (the active bellow). When the active below is compressed, the second expands, and vice versa, resulting in the movement of the liquids in the capillary.
As the hours go by, the coloured liquid advances. The meniscus, in the shape of a small half moon, marks the separation point between the two liquids, indicating the hour. At 18:00, the coloured liquid moves backwards, returning to its original position in what is known as a ‘retrograde’.
In 2013, HYT launched its H2 Collection, a new class of time pieces born from a close partnership with Audemars Piguet Renaud Papi and managed under the steady guidance of Giulio Papi. This partnership was renewed in 2015 to continue HYT’s ground-breaking work in fluid technology and also to develop a new collection: the H3 that once again reiterated HYT’s commitment to creating pieces that continuously surprise and challenge at every opportunity.
In 2015 two more legendary collections were introduced: the Skull & the H4. The most difficult aspect when creating the Skull was to transform the circular shape of the capillary to give it a skull like appearance. This was due to both the technical and the esthetical constraints of bending a glass tube that measures less than 1 millimeter in diameter. The H4 is equipped with a micro generator that converts mechanical energy into light allowing the wearer to read the time in the dark. A first in the horological industry.

Who's who



HYT was born of a question. Time flows and only gains meaning through content. So why limit its measurement to indicating the now in splendid isolation, with needle-sharp hands or fleeting digital displays?  Determined that its rebellion should make statements and waves, a multi-disciplinary think-tank set out to create timepieces that visibly connect the past, present and future. The HYT answer is a watch that overcomes the force of gravity to indicate the passage of time with liquids. Highly advanced technology took its cue from philosophy to mirror time’s intrinsic fluidity. 


The rest is history. To be precise, it’s history that began 3,400 years ago with the Clepsydras, or water clocks, of the Pharaohs. These so-called “water thieves” transported H2O from one container to another to measure elapsed or “stolen” time. This meaningful visualization of the transition of time seemingly disappeared until 2012, when HYT broke new scientific ground, inventing a wristwatch integrating a patented fluidic module. A colored liquid documents the recent past; a transparent fluid indicates the foreseeable future. Their meeting point is a meniscus, aka the now.


Today HYT is an ecosystem that unites science, hi-technology, philosophy, art and design. Based in Neuchâtel, at the heart of the traditional Swiss watchmaking region, a dedicated team of 43 individuals makes liquid time real time. Their radical wristwatches harmoniously incorporate a mechanical watch movement as the trigger to the fluid propulsion. They make total sense of time – time and time again. 





For HYT, technology is the stuff that dreams are made of. Dreaming of visibly linking the past, present and future and of defying gravity set the bar high. Today’s reality is a watch that breaks new scientific ground, measuring time’s passage with a patented fluidic module that took 15 years of inspiration to develop. HYT timepieces are portable hubs of technical firsts and fascinations, dedicated to making sense of time in the twenty-first century. Radical is the new relevant.


Liquid timekeeping is the HYT answer to capturing time’s flow and context as opposed to an isolated current moment. Two bellows, with walls four times finer than a human hair, form the engine of the fluid module. As each one compresses or expands, it releases or receives one of two immiscible liquids, one colored and one transparent. These correspond to elapsed or imminent time respectively. Advanced chemistry was the mentor for the in-house development of a liquid dye with the required visibility, esthetics, durability and UV resistance. The meeting of the liquids, i.e. the now, is termed a "marriage". This can only take place between two fluids that complement each other while maintaining their intrinsic individuality. Assuring the long-term reliability of this innovative timekeeping method is proprietary testing equipment with the ability to accelerate time, reducing a year to a month. Twice a day the fluid module issues an open invitation for reflection as the colored liquid that has plotted the course of the last 12 hours flows back to its original position. Back to the future in horological form.


Liquid time obtains its rhythm from a specially created haute horlogerie mechanical movement that interfaces with the two bellows. Front of stage, the visible proof of accuracy is the domain of a curved 0.8 mm thin glass capillary. The capillaries’ coating, eliminating any obstacle to flow, ranks as one of the watch’s most expensive elements. Full transparency is a further must in the quest to visualize time. Technicians spend a full year perfecting the technique of filling the capillary. Even the smallest of air bubbles could threaten accuracy, especially at altitude. The technology portfolio in every HYT watch shows that the whole is much more than the sum of its parts - and that time standing still is never an option.

He has worked for major brands, including Cartier, in Retail / Marketing strategy and in the reorganisation of jewellery activity, followed by the Swatch Group and Calvin Klein Watches, and also the Management board of manufacturing companies under Nicolas Hayek Senior. He then founded his own consulting company, working on performance enhancement and development projects for companies operating in the medical, watchmaking and high-tech sectors, among others. His interest in and passion for fields as diverse as the physical sciences, biology, philosophy, plastic arts and music, reveal a desire to nurture and enrich ideas through an interdisciplinary approach, using this cross-pollination as the basis for research into innovative and original solutions.
