Greubel Forsey GMT Balancier Convexe

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.

Greubel Forsey unveils its new GMT Balancier Convexe. As the Earth takes centre stage within a newly reimagined amphitheatre, the hours, minutes, seconds, second time zone, and universal time indications become both companions and spectators to its quiet revolution.

The new GMT Balancier Convexe replaces its predecessor entirely – not as a variation, but as a complete reinterpretation. With a redesigned case, an integrated power reserve, and enhanced ergonomics, it becomes the purest expression of our GMT complication to date – and the only GMT model in our current collection.

A refined evolution
– Titanium Convexe case now more compact at 42.90 mm for improved wearability.
– New 72-hour power reserve indicator seamlessly integrated into the dial.

Technical enhancements
– 496 components, 73 more than its predecessor.
– Inclined escapement suspended beneath polished steel bridge.
– Real-time rotating globe in layered amphitheatre.
– Sapphire disc on caseback with 24 cities, La Chaux-de-Fonds replaces Paris.

Exclusivity
– Limited to 22 pieces worldwide.

Greubel Forsey proudly unveils the QP Balancier, a revolutionary interpretation of the perpetual calendar that merges intuitive functionality with uncompromising chronometric performance. Limited to just 22 pieces in white gold, this timepiece represents a new pinnacle in haute horlogerie.

At the heart of the QP Balancier lies Greubel Forsey’s patented Mechanical Computer, a 25-part mechanical brain that “understands” the rules of the Gregorian calendar. This innovation allows the watch to adjust instantly in either direction, restart flawlessly after months unwound, and remain programmed until February 28, 2100—all without the need for pushers or complex crown positions.

The QP Balancier integrates 12 indications—including hours, minutes, seconds, power reserve, day, date, month, leap year, day/night, 24-hour display, calendar year, and a patented function selector—into a single crown interface. This makes it the most user-friendly perpetual calendar ever created, eliminating the need for manuals or reset tools.

Aesthetically, the watch is a study in purity and harmony. Its multi-level gold dial presents calendar information in a clear, linear format, flanked by leap year and day/night indicators. The tactile feedback during quick-correction mode offers a unique sensory connection between wearer and mechanism.

Housed in a 45.1 mm white gold case, the QP Balancier features Greubel Forsey’s signature 30° inclined balance wheel, a high-mass, variable-inertia system with gold mean-time screws. The movement comprises 612 hand-finished components, including twin fast-rotating barrels that deliver a 72-hour chronometric power reserve.

With the QP Balancier, Greubel Forsey has not only redefined the perpetual calendar—it has perfected it.

Greubel Forsey has officially released the Nano Foudroyante, a groundbreaking timepiece that blends cutting-edge nanomechanics with refined craftsmanship. Limited to just 22 pieces, this watch marks a major milestone for the brand, evolving from its earlier Experimental Watch Technology (EWT) concept into a fully developed and independent creation.

The Nano Foudroyante is crafted entirely in white gold and features a rhodium-finished dial with a blue minute track, blued steel hands, and a white foudroyante dial for enhanced legibility. A blue textured rubber strap completes the look, giving the watch a modern and sporty edge.

What sets this timepiece apart is its use of nanomechanics—a revolutionary approach that allows the foudroyante complication to operate using just 16 nanojoules of energy per jump. That’s 1,800 times less than traditional designs. The complication divides each second into six parts, with a red-treated hand rotating once per second, driven directly by the balance wheel. There’s no traditional gear train, just a series of ultra-efficient, low-inertia wheels.

The Nano Foudroyante also features Greubel Forsey’s first flying tourbillon, with the foudroyante dial always facing twelve o’clock for easy reading. Despite its complexity—428 components in total—the movement fits into a compact 37.90mm case, making it the smallest Greubel Forsey watch ever made.

This release is a bold statement of innovation and intent, offering collectors a rare opportunity to own one of the most advanced mechanical watches ever created..
