Greubel Forsey introduces the final and most exclusive editions of the Balancier Convexe S²: one in black ceramic with 5N red gold, and one in white ceramic, each strictly limited to 11 pieces.
These editions conclude a calibre developed through five years of mechanical and architectural exploration, with production set to cease permanently in 2026.

The Convexe case (41.5 mm) and movement were conceived as a single architectural whole, integrating Greubel Forsey’s signature 30° inclined balance wheel system as the visual and chronometric centre. The openworked movement features 301 components, including a 68‑part escapement platform, and is powered by two rapid-rotation coaxial barrels delivering a 72‑hour chronometric reserve.

Finishing remains uncompromising: frosted titanium bridges, polished bevels, hand‑finished countersinks, and meticulous transitions — even on invisible components.

Two Final Interpretations
Black Ceramic & 5N Red Gold
A dramatic contrast of dark architecture framed by ceramic, with red gold adding warmth and sculptural depth.The interplay of matte and polished surfaces enhances the piece’s three‑dimensional form

White Ceramic
A purist, graphic expression that highlights the structural geometry of the movement through light and shadow.The monochromatic case offers clarity, openness and a distinctly technical aesthetic.

Both editions preserve the characteristic S² display: suspended hours/minutes bridge, small seconds, and sector power‑reserve indication beneath a curved sapphire crystal.

This launch marks the concluding chapter of the Balancier Convexe S²’s five‑year evolution — not an iteration, but a final statement. As of 2026, Greubel Forsey will begin a gradual shift toward an almost entirely new collection, retiring earlier calibres with intention and ceremony rather than quiet discontinuation.

Angelus unveils the Flying Tourbillon Skeleton Titanium, Orange Edition, a vivid expression of horological energy and design. Limited to just 25 pieces, this timepiece transforms skeletonised mechanics into a canvas of colour and contrast. The satin-finished titanium case frames a deep black movement, animated by bright orange accents that highlight the time display and extend to three interchangeable straps. The openwork calibre, designed as a series of interlocking circles, adds architectural depth and visual dynamism.

Every detail of this 42.5 mm watch reflects a unique energy. Chromatic energy flows through the orange highlights. Customisable energy is offered by the quick-release strap system, allowing seamless transitions between black alligator leather, orange rubber, and integrated titanium. Light energy emerges from the skeletonised movement, while structural energy is revealed in the layered construction. Graphic energy is embodied in the three-dimensional architecture of the A-310 calibre.

The dial features a floating orange minute track above a black flange, with hour markers crafted for the first time by Angelus in monolithic blocks of Super-LumiNova. These luminous elements ensure legibility in low light and reinforce the watch’s modern aesthetic. At the heart of the case lies a carbon composite chamber, lightweight yet rigid, surrounded by a modular titanium cage that enhances stability and mechanical appeal.

The A-310 calibre showcases Angelus’s signature three-spoke wheels, leading the eye to the flying tourbillon suspended without an upper bridge. Supported by a 160° angled bridge, this asymmetrical design intensifies visual tension and balance. The tourbillon completes a rotation every minute, oscillates at 4 Hz, and offers a 60-hour power reserve. The Flying Tourbillon Skeleton Titanium, Orange Edition embodies the Angelus L.A.B. philosophy—Legacy and Beyond—where technical mastery meets bold design to elevate mechanics into contemporary art.

Independent manufacture Greubel Forsey has unveiled the Balancier QM ($GF09cm$), marking a historic milestone for the workshop by officially naming its highest, most uncompromising hand-finishing standard: Qualité Musée (Museum Quality). While this meticulous level of execution has been quietly embedded into every single timepiece crafted by the Atelier since its founding in 2004, the Balancier QM is the first model to formally carry the designation. Driven forward by a dedicated research wing within the brand’s proprietary EWT (Experimental Watch Technology) Laboratory, this standard mandates that every individual component, whether fully visible through the sapphire crystals or buried deep within the gear train, must hold up as a standalone work of art.

The mechanical architecture of the Balancier QM is a tour de force of in-house micro-engineering and innovation. Most notably, the timepiece features a specialized hairspring manufactured entirely in-house from the raw alloy stage up—a rarity in modern watchmaking accomplished via restored antique machinery. This is paired with an impressive $12.60\text{ mm}$ variable-inertia balance wheel and a cutting-edge bi-level escapement system that utilizes unique convex pallet-jewels, allowing light to softly diffuse through the rubies rather than abruptly reflecting off flat surfaces. Illustrating the immense labor required for the Qualité Musée standard, the steel balance wheel bridge alone requires seven distinct hand-finishing techniques, ranging from flawless mirror barrel polishing to extra-large $0.40\text{ mm}$ hand-polished bevels.

Visually, the timepiece presents an intricately layered, three-dimensional landscape neatly organized within a highly compact 39.60mm white gold case. The movement architecture encourages deep visual exploration; the escapement is nestled into the lowermost depths of the chassis, while the eye naturally ascends past a high-set small seconds sub-dial, flame-blued polished steel hands, and a raised chapter ring. Beneath this upper track, a power-reserve indicator slips mysteriously across a dedicated sector to track the watch's 72-hour chronometric power delivery, sustained by two fast-rotating, series-coupled mainspring barrels. True to Greubel Forsey’s signature underplayed luxury, the words "Qualité Musée" are entirely absent from the dial, hidden instead on a secret internal plate deep inside the movement.

Limited to just 33 exclusive timepieces worldwide, the Balancier QM represents a deliberate strategic pivot for Greubel Forsey toward smaller, more wearable case dimensions without sacrificing an ounce of technical complexity. The manufacture openly acknowledges that achieving this level of structural perfection across all 298 movement parts demands an extraordinary expenditure of time, which will intentionally reduce the company's overall production volume heading into 2027. Looking ahead, the Qualité Musée standard will serve as the foundation for a series of compact releases, including a highly anticipated movement under development at the EWT lab featuring a gear train crafted entirely from solid gold.
