A new brand

The Dominique Renaud brand is the second expression of HHDR. “Through this watchmaking signature, Dominique Renaud now presents the most accomplished version of his work as an inventor and designer.” (Michel Nieto, CEO of HHDR)

Dominique Renaud here expresses a powerful watchmaking principle that determines the form—disruptive and minimalist. The formal clarity and sense of purity make a Dominique Renaud watch feel self-evident. The watchmaking language deployed here could only be expressed within a new kind of envelope. “A Dominique Renaud can be recognized from afar: its architecture and the unique spectacle of its display illustrate a truly distinctive watchmaking stance.”

With each new creation, the Dominique Renaud brand will lay claim to this exploratory watchmaking that transcends established codes and privileges the total coherence of function determining form.

The expression of a singular figure

Historical legitimacy: Dominique Renaud is the legendary designer behind dozens of prestigious complications created for illustrious maisons. He was a pioneering movement specialist who developed complications for major houses. He became a key figure in the industry through the mythical Renaud Papi manufacture, later sold to Audemars Piguet.

Collective spirit: Dominique Renaud never designs alone. He shares, listens, tests, challenges, and co-builds. Like any great watchmaker, Dominique Renaud cultivates a collaborative, experimental and humble approach to his craft.

Watchmaking inventor: Dominique Renaud is a watchmaking inventor who looks to the world for inspiration. Nature and the mountains are an essential source of creativity for him. Like any inventor, he prepares a future that he alone can see. That is what makes him fundamentally nonconformist. Dominique Renaud rethinks, questions and reinvents the very foundations of movement.

The Pulse60

Features

At the heart of the Pulse60 is a completely new movement, the Dominique Renaud BUA2024 — for Balancier Ultra Amplitude with a development that started in 2024.

Exploring the extremes of frequency

“By exploring the extreme regimes of watchmaking, I sought to show that it is possible to move beyond standards, and even rethink the balance-escapement interaction.”

Dominique Renaud is known for having pushed the limits of the regulating organ, notably with a very high-frequency, low-amplitude balance: 12 Hz for just 30 degrees, whereas the industry average lies between 2.5 Hz and 5 Hz. This radical approach already illustrated his spirit as an explorer and inventor. That experience forms the basis of Dominique Renaud’s current reflection: understanding through practice what frequency truly changes in the behavior of a movement.

“One way of solving watchmaking challenges is to tackle a problem through its exact opposite.”

Rather than continuing to explore high frequency, he became interested in the benefits of the lowest one possible in contemporary mechanical watchmaking: 1 Hz. Here, the balance oscillates only once per second—60 beats per minute, equivalent to the resting frequency of a human heart. Where high frequency sought precision through multiplying events, low frequency seeks accuracy through mastering rhythm.

By bringing watchmaking frequency back to that of living beings, Dominique Renaud goes beyond a technical choice: he reconnects watchmaking with our humanity, introducing a notion of time that is embodied rather than abstract.

This bold low-frequency approach drastically reduces the number of impulses and shocks in the escapement over a given period, thereby limiting the disturbances that pollute the natural motion of the balance. The second becomes a structuring unit of time, paced by the balance’s single to-and-fro motion, around which the entire movement is organized.

A large balance wheel to master the second

To fully harness this low frequency, the movement relies on a very large 20 mm balance wheel with high inertia, in the spirit of the massive balances found in marine chronometers. Once in motion, this balance tends to maintain its movement and resists variations in torque or minor shocks far better. Its significant moment of inertia acts as a mechanical “buffer”: small disturbances represent only a tiny fraction of the total energy stored in the oscillation, so their influence on the rate becomes negligible.

Like a tightrope walker

This balance can be compared to a tightrope walker crossing a wire: the longer the pole, the more stable the center of gravity becomes and the less the disturbances throw it off balance. With a short pole, each disturbance would have a much greater impact and would force the balance to correct its position constantly. This large balance acts like a long mechanical pole, stabilizing the rate over the second: it absorbs small variations, smooths out irregularities, and turns each tick-tock into a slow, broad, controlled beat.

Ultra-amplitude: far from the limiter

In most conventional movements, the geometry of the balance, roller and impulse pin imposes a strict amplitude limit; beyond a certain angle, “knocking” occurs, when the balance swings too far and strikes the back of the pallet fork, causing the watch to gain time.

Dominique Renaud has therefore completely rethought the construction of this ensemble so as to allow amplitude greater than 360° without knocking, whereas a traditional coaxial architecture is mechanically constrained well below that threshold. This newfound freedom in the design of the regulating organ opens an amplitude range previously unexploited in a wristwatch.

“Imagine a movement as a car engine: the Pulse60 would be an engine whose operating range lies far from the redline.” Dominique Renaud

This can be illustrated by the metaphor of an engine. A traditional movement functions like a limited engine whose normal operating range already lies close to the red zone: at the slightest increase in load, the engine hits its limiter—the watchmaking equivalent of knocking.

With a theoretical maximum amplitude of around 700 degrees, the Pulse60 functions like a better-protected engine whose operating range lies far from the redline. Even when available energy is at its maximum or in the event of disturbances, the amplitude remains within a safe zone, thereby protecting rate regularity.

A vision of the ideal oscillator

This large amplitude is not merely a geometric feat; it directly affects the way the balance is regulated. By increasing the freedom of the oscillation, the balance remains free for longer and over a greater distance before and after the impulse. Within this expanded interval, its motion is governed more by its own dynamic laws than by interactions with the escapement. The relative influence of each impulse therefore decreases, helping to make the rate more stable and less sensitive to micro-variations.

As a result, the number of disturbances experienced by the balance is reduced to a minimum. The resulting static rate stability is remarkable, with each position benefiting from more controlled behavior. This stability makes it possible to optimize the simulated average rate by having a better positional stability of the watch.

Aesthetics

The Pulse60 had to make such innovations visually crystal clear and pay tribute to this mechanical exploration.

The case is inspired by a search for continuity and the absence of edges: a domed crystal, the disappearance of the bezel and the absence of lugs all facilitate a borderless integration with the strap. Its construction is composed of three parts, with a central container and sections integrated into each side of the strap, once again underscoring true mechanical ingenuity.

At launch, the watch comes in 2 versions and 3 colorways: titanium, or a bi-material pink gold and titanium version. The grey or black dials of the titanium version feature a opaline base with diamond-cut openings, while the bi-material version presents a guilloché dial that interprets a traditional technique in a modern way. The case features a circular satin-brushed top evoking pieces from the 1970s, a period dear to Dominique Renaud, as well as polished flanks that create a sharply contrasting profile.

The integrated strap, developed specifically for the Pulse60, is secured by an interchangeable system that is both invisible and easy to use.

The Pulse60 display includes an hour/minute dial at 12 o’clock, a seconds counter at 9 o’clock with a natural dead half-second made possible by the 1 Hz frequency, which corresponds to one to-and-fro motion of the balance per second. A unique feature is the patented regulating system that has been positioned outside of the the balance wheel and which makes it possible to admire the spectacle of this large low-frequency balance wheel in an unobstructed way.

The Pulse60 display also includes a torque indicator at 3 o’clock, which takes information on the remaining power directly from the barrel, a system Dominique Renaud had already worked on during the Renaud Papi era.

Finally, the open back of the Pulse60 presents a streamlined arrangement of elements using simple forms: circle, half-circle and straight lines. In the upper part, the crown wheel and ratchet; in the lower part, an openworked escapement line highlights the particular architecture and an offset double roller system.

HHDR, a maker of ideas and objects

Purpose

Dominique Renaud has surrounded himself with an ecosystem to bring his creations to life. This is how Haute Horlogerie Dominique Renaud (HHDR) came into being, both a place of creation and a multidisciplinary constellation of talents.

HHDR is a living laboratory, an incubator where vision takes shape collectively. It is first and foremost a place of convergence before being an integrated manufacturing chain. At HHDR, expertise, trajectories and ideas meet.

By integrating profiles from diverse backgrounds, HHDR deliberately broadens the traditional framework of watchmaking and thus becomes a maker of ideas as much as of objects, rooted in Swiss mechanical tradition yet oriented toward contemporary technologies and uses.

The nest of watchmaking genius

HHDR’s purpose is to set a collective dynamic back in motion—that of watchmaking genius. “We needed a very special place to accommodate the research, experimentation and long-term approach characteristic of our disruptive watchmaking.” (Dominique Renaud)

HHDR therefore established itself in Tolochenaz, at the heart of the Swiss watchmaking arc, to serve as the epicenter of its watchmaking ambition. This place embodies Dominique Renaud’s approach: an architecture that encourages the circulation of ideas while remaining closely connected to nature.

Today, nearly twenty people—watchmakers, designers, engineers and experts—collaborate and explore new forms of watchmaking here with rigor, coherence and freedom. This is where creations inspired by Dominique Renaud’s creative paradigm will come to life. Various explorations are conducted here in parallel, each driven by the single mantra of reconfiguring contemporary watchmaking.

Renaud Tixier, the inaugural language of HHDR

Renaud Tixier was the first concrete expression of the method championed by HHDR. Led by Dominique Renaud and developed with the young watchmaker Julien Tixier, this collaboration gave birth in 2024 to the Monday, the founding watch and manifesto piece of this brand.

“Monday was born from a desire to re-examine the archetypes of traditional watchmaking.” (DR) It embodies the conviction that innovation is born from dialogue between generations, between intuition and rigor, between experience and a fresh perspective.

Monday is part of the continuity of a companionship already initiated between Dominique Renaud and Julien Tixier, notably through projects such as Tempus Fugit (2022) or the secular calendar watch created for Furlan Marri (2023).

Monday thus concentrates the DNA of Renaud Tixier: a watchmaking of fertile tension, between tradition and invention, transmission and renewal.
