A PIVOTAL ENCOUNTER, A NATURAL PROGRESSION
Renaud Tixier epitomizes a unique alliance in the world of horology, the natural next step in the friendship of two extraordinary watchmakers, combining their expertise in watchmaking, invention, and creativity, from conception to execution: Dominique Renaud, an innovator who was instrumental in the renaissance of Haute Horlogerie in the late 1980s; and Julien Tixier, watchmaker extraordinaire and a leading figure of his generation, born in the 1990s.

Dominique Renaud was the driving force behind
Renaud & Papi (co-created in
1986 with his friend
Giulio Papi), the first-ever independent movement developer and manufacturer in horology.
Renaud & Papi was responsible for numerous groundbreaking creations that have marked contemporary watchmaking history, contributing to the growth and glory of prestigious Maisons such as
IWC, Lange & Söhne, Jaeger-LeCoultre, Audemars Piguet, and Richard Mille. Click, to see the large size. ▶ BIG FOTO 
Around the turn of the millennium, as the firm entered into the orbit of
Audemars Piguet, Renaud & Papi was the springboard for many talented watchmakers who have since become key figures in independent creative watchmaking, including
Robert Greubel (of
Greubel Forsey),
Andreas Strehler, and Bart Grönefeld. Following Audemars Piguet’s acquisition of Renaud & Papi in
2000,
Dominique Renaud pursued the path of an independent and relocated to the south of
France. He returned to Switzerland about twelve years later to focus on developing his own inventions. It was during this time that he met a young watchmaker whose talents left an indelible impression on him:
Julien Tixier. Click, to see the large size. ▶ BIG FOTO
Dominique Renaud and
Julien Tixier discover their deep connection at the workbench, combining their talents to create several exceptional timepieces in tandem. The ways in which the two complement each other are as uncanny as they are evident: together, they possess the combined creative power of an
R&D laboratory and a manufacturing workshop.

In
2020 and again in
2023, they collaborated to create two exceptional unique timepieces:
Tempus Fugit and the simplified and modular secular perpetual calendar for
Furlan Marri. The birth of a brand bearing their names was not a surprise, but rather the natural result of a genuine and unique affinity for the art of watchmaking.

In
2023,
Dominique Renaud and
Julien Tixier decided to formalize their synergy by founding their brand,
Renaud Tixier, supported by a production and distribution structure, the Manufacture
Dominique Renaud.
CHAPTER 1: ‘MONDAY’
‘Monday’, the inaugural creation and first chapter of Renaud Tixier’s journey, delves into the most sensitive aspect of mechanical watches, energy generation, by revisiting a classic of Haute Horlogerie: the micro-rotor. Their first milestone is an invention that transforms a weakness into a strength – through the dancer, a micro-rotor engine at the heart of the winding mechanism.

For this first timepiece,
Dominique Renaud chose to tackle the most fundamental aspect of mechanical watches: energy. He went back to the origin of this energy — the rotor of the automatic watch, a mechanism that has seen little development since its industrial standardization in the
1930s and
40s.
Click, to see the large size. ▶ BIG FOTO He then narrowed his focus to the micro-rotor, which represents a higher level of horological sophistication compared to the larger, mass-produced rotors that are commonly used. The micro-rotor is smaller, more elegant, and does not obscure the mechanics. There is a downside, however: it is a more delicate and less efficient winding system.

Before starting to work on improvements,
Dominique Renaud identified the key weakness: to function properly, the micro-rotor requires a large amplitude of movement. Yet, the wristwatch is constantly subjected to opposing forces: all the small jolts naturally caused or encountered by the wearer – like typing on a keyboard or gesturing during a conversation, for instance – that constantly halt the rotor’s acceleration.
Click, to see the large size. ▶ BIG FOTO This led him to the crucial question: how to harness all the energy generated by the wearer, including restoring the energy from these constant minor shocks that a traditional micro-rotor is unable to convert?
A ‘DANCER’ IN THE SPOTLIGHT
With the goal of finding a solution within the realm of micromechanics, without relying on any external technology, Dominique Renaud envisaged a watchmaker's response. He began by searching for a space where he could operate. He found it at the heart of the rotor, where only the periphery is active and the center is, in fact, underutilized.

Thus, it was at the center of the rotor that he decided to install the auxiliary mechanism. This mechanism had to fulfill a very simple sequence: to optimize the use of energy released by the rotor and harness even the slightest joule to power the watch. As usual,
Dominique Renaud visualized the problem in his mind, and the solution emerged naturally: a central ‘engine’ for the micro-rotor. This propeller, animated by an intelligent and flexible spring, literally dances at the heart of the mechanism, aptly named the "dancer."
Click, to see the large size. ▶ BIG FOTO Having established this basic principle,
Dominique Renaud further refined his vision by focusing on another ‘trait’ for his ‘dancer’. By adding a ‘leg’ and a ‘foot’, he could make the dancer serve both as an engine and a shock absorber. The corollary is that the system acts as an active safety feature, capable of absorbing the most violent shocks and converting their energy, much like the strings of a tennis racket, which store energy and then release it like a catapult.

Click, to see the large size. ▶ BIG FOTO Technically, the ‘dancer’ is a high-flying athlete. It consists of several parts, with complex geometries, even though they perform elementary functions. A large spiral connects the central axis to the innovative mechanism, acting as a catapult. Another spring arm extends from the axis in the opposite direction: a kind of foot with a heel, which hits a stop in the event of a severe shock, serving as the shock absorber.

On the axis, the spring operates like a notched clamp, with an upper jaw shaped like a hanger. This hanger acts as an active safety device: it is rigid under normal conditions and secures flywheel to the axis. In the event of a shock, the foot hits the stop and presses on the hanger, which disengages from the axis and the repositions once the shock has passed and stored energy is released.
EXECUTION
As is customary with Dominique Renaud, the experts and specialists working with him have to get used to navigating terrain that has not yet been mapped by theory. Watchmaker Julien Tixier is already well-versed in this practice. Other members of the collective, engine builder Alexandre Bugnon and prototype watchmaker Sébastien Rousseau, have come to discover this, too.

This is understandable, since, in principle, any element added to a mechanism designed to be as free as possible is a constraint – it adds friction and hinders the mechanism’s proper functioning. However, in this instance, the opposite occurs: the constraint generates energy.

True to form for
Dominique Renaud, the invention is first tested on a large-scale model – the calculations come later. And this is where the real challenge begins, as the usual calculation methods for the micro-rotors do not apply here.
Click, to see the large size. ▶ BIG FOTO On the model, there is no doubt that the mechanism enhances the efficiency of the micro-rotor. This improvement is expected to be confirmed by the watch prototype. By how much? It is too early to say: no existing control tool is capable of quantifying the difference it will make.
AESTHETIC CHOICES
The ‘Monday’ project goes beyond mere invention. It involves a completely new caliber that has been designed, developed and created around the ‘dancer’ micro-rotor, showcasing this innovative mechanism – and illuminating its significance. Here, mechanics are at the heart of the design, with the focal point on energy generation – from the micro-rotor to the barrel, and from the barrel to the balance wheel.

The ‘dancer’ takes center stage in this horological performance. Its natural elasticity is echoed by the unusual architecture of the bridges – light and arched like catapults – stretched over the micro-rotor, gear train, and the balance wheel. The finishes set the stage for a contemporary production, with each detail aiming for perfection: beveling by hand, mirror-polished titanium, a palladium balance wheel.
