Haute Horlogerie Dominique Renaud (HHDR) marks its official debut with the launch of the Pulse60, unveiled in preview at the Time To Watches fair in Geneva (April 14–19, 2026). This first creation of the new Dominique Renaud brand introduces a radical approach to low‑frequency mechanical watchmaking and expresses the purest form of Renaud’s watchmaking philosophy.

A Vision Rooted in First Principles
Dominique Renaud, co‑founder of the legendary Renaud & Papi manufacture and creator of numerous landmark complications, returns with a renewed focus on foundational movement principles. Guided by the maxim “form ever follows function,” his work embraces clarity, purity and a minimalist, self‑evident aesthetic.
The establishment of HHDR in Tolochenaz brings together a team of watchmakers, designers and engineers in a collaborative, idea‑driven environment. HHDR is conceived as a living laboratory — a place where experimentation, shared expertise and long‑term exploration shape new forms of contemporary horology.

Pulse60 — A New Mechanical Language
At the heart of the Pulse60 is the newly developed BUA2024 movement, which embraces an ultra‑low 1 Hz frequency — just one oscillation per second, echoing the natural rhythm of the human heart. This approach reduces escapement shocks and disturbances, transforming time measurement into a slower, more embodied rhythm.

To master this low frequency, the movement features a monumental 20 mm high‑inertia balance wheel, inspired by marine chronometers. Its large moment of inertia stabilizes the rate by absorbing minute variations in energy and motion.

Dominique Renaud has also completely reimagined the regulating organ, allowing amplitude greater than 360° without knocking, with a theoretical range reaching approximately 700°. This unprecedented freedom greatly improves static rate stability by allowing the balance to follow its own natural dynamics over a longer portion of its oscillation.
 

A Design That Expresses Its Mechanics
The Pulse60’s innovative mechanics are reflected in its seamless, fluid architecture:

- A domed crystal with no bezel
- Lug‑less construction and integrated strap
- Three‑part case structure
- Diamond‑cut or guilloché dial details
- A patented offset regulation system placed outside the balance wheel, offering a completely unobstructed view of the slow‑beating 1 Hz oscillator

The display includes an hour‑minute dial at 12 o’clock, a natural dead half‑second at 9 o’clock, and a torque indicator at 3 o’clock. The caseback reveals a minimalist composition of circular and linear forms, framing the openworked escapement line and double‑roller assembly.

The Maison gérald genta expands the Geneva collection with the Geneva Time Only, a new 38 mm creation in warm rose gold 4N and cool white gold, translating the line’s sculptural language and “l’esprit de Genève” into an essential, everyday expression.

“I wanted to capture the intuitive, instinctive genius and artistry of Mr. Genta,” says Matthieu Hegi, Artistic Director at La Fabrique du Temps Louis Vuitton, who leads the Geneva collection’s creative direction.

The updated cushion case—neither round nor square—features softened contours, a refined gadroon and a new single, broader lug on each side, striking a rare balance of daring and discretion. Light plays across polished and satin surfaces, while the collection’s signature two‑segment minute track forms a subtle optical illusion as the outer track follows the cushion silhouette and the inner ring remains perfectly circular. The grained brass dial carries a gentle fumé gradient—lighter at the center, darker at the edge—for tonal depth.

At just 8.15 mm thick, the 38 mm case slips neatly under a cuff; both models are fitted with rounded, mirror‑polished solid‑gold hands and applied indexes and tone‑on‑tone calfskin straps. Under the dial, the GG‑005P automatic calibre—Zenith Elite–based with redesigned bridges and a reworked oscillating mass—beats at 4 Hz with a 50‑hour power reserve (158 components, 27 jewels), visible through the sapphire caseback. Water‑resistance is 30 m.

Arnold & Son introduces a radiant new chapter in feminine watchmaking with the Perpetual Moon 38 White Gold Aventurine Edition. Limited to just 18 pieces, this poetic timepiece captures the magic of moonlight and the brilliance of the stars.

Encased in 18-carat white gold, the 38 mm watch features a dial crafted from blue aventurine glass, evoking a starlit sky. The bezel, lugs, and crown are adorned with 80 brilliant-cut diamonds, while 12 marquise-cut diamonds mark the hours. At its heart lies a mother-of-pearl moon disc, framed by hand-painted constellations of Ursa Major and Cassiopeia, enhanced with Super-LumiNova for a celestial glow.

Powered by the A&S1612 manual-winding movement, the watch offers a 90-hour power reserve and an astronomically precise moon phase complication that deviates by only one day every 122 years.

The "Midnight Purple" story continues at Armin Strom with a bold new chapter. This distinctive colour, deeply rooted in the history of the independent manufacture and inherited from founder Armin Strom himself, now extends beyond the dial and into the movement itself. Expressed through the newly released Orbit Midnight Purple, the signature midnight purple fumé dial remains at the centre of the composition, paired for the first time with a frosted midnight purple mainplate beneath to strengthen the visual connection between display and mechanics.

Powering the watch is the manufacture Calibre ASS20, developed and produced entirely in-house around the world's first on-demand date display on a ceramic bezel. This innovative mechanism rethinks the relationship between wearer and complication by displaying the date only when requested. Activated by a pusher at 10 o'clock, the date hand moves from its neutral position to indicate the current date on the bezel and advances automatically at midnight. A second press returns it discreetly to 12 o'clock, leaving the dial free from unnecessary information.

Beyond its avant-garde functionality, the timepiece focuses heavily on exceptional visual details. Hand-polished steel hands and applied hour markers are filled with Super-LumiNova®, complemented by signature numerals at 12 and 6 o’clock crafted from solid Super-LumiNova® blocks that create a striking visual presence after dark. Housed in a 43.4 mm stainless steel case framed by a black ceramic bezel, the timepiece is completed by a fully integrated stainless steel bracelet, delivering a cohesive fusion of modern sports-luxury and unique aesthetics.

Visible through the sapphire crystal and caseback, the movement highlights Armin Strom's dedication to transparent mechanics and haute horlogerie finishing. The purple mainplate creates a distinctive visual foundation, contrasting with rhodium-coated components and hand-finished finger bridges, while hand-polished bevels, perlage, and circular graining enrich every surface. To ensure both mechanical precision and finishing excellence, each watch is assembled twice. Limited to just 20 pieces worldwide, the Orbit Midnight Purple is one of the most recognisable and collectible expressions of the System 78 collection to date.

Armin Strom has masterfully fused its revolutionary resonance technology with a bold, contemporary aesthetic in the new Mirrored Force Resonance Red. Limited to just 15 pieces worldwide, this rare masterpiece introduces a striking off-centre guilloché dial in vibrant red. By pairing traditional hand-crafted artistry with the brand’s signature open-worked design, this timepiece breathes dynamic new energy into Armin Strom's celebrated dual-balance mechanism, creating a captivating dialogue between classic hand-finishing and cutting-edge mechanical architecture.

The brilliant red dial is hand-crafted on a traditional, manually operated rose engine lathe, engraving a radiating pattern that catches and plays with light in captivating reflections. Encircled by black azuré (蝸形紋) chapter rings and topped with faceted, floating index markers, the dial's layout creates a stark, three-dimensional contrast that maximizes both visual depth and legibility. Housed in a polished 43 mm stainless steel case, the movement's technical architecture is framed by anthracite-coated bridges and paired with a dark grey Alcantara strap—ensuring that the vibrant red dial and the synchronized dance of the resonance mechanism remain the undisputed center of attention.

At the heart of this technical marvel lies the in-house Calibre ARF21, a hand-wound movement that integrates two completely independent movements within a single calibre. Connected via Armin Strom's patented Resonance Clutch, the two opposing balance wheels transfer vibrations to enter and maintain a perfect state of harmonic resonance. This physical synchronization significantly improves chronometric stability and rate consistency over time. To let wearers witness this horological phenomenon in action, a pusher at 2 o'clock activates a flyback mechanism, resetting both independent seconds hands to zero simultaneously so their perfect synchrony can be monitored in real-time.

Every millimeter of the Mirrored Force Resonance Red showcases Armin Strom's uncompromising dedication to haute horology standards, featuring meticulous hand-polished bevels, perlage, circular graining, and mirror-black polished screws. On the reverse side, the main plate features technical inscriptions rendered in three-dimensional relief, rising directly from the metal's surface. As is tradition for the Swiss manufacture, each watch is assembled twice to guarantee absolute precision. For collectors seeking the pinnacle of independent Swiss watchmaking, this 15-piece limited edition represents a perfect harmony of mechanical science and artistic expression.
