GREUBEL FORSEY – TOURBILLON 24 Secondes Architecture GFO1h Final Titanium Edition

GREUBEL FORSEY – TOURBILLON Tourbillon 24 Secondes Architecture GFO1h Titanium Edition 2026

First presented in 2022, the Tourbillon 24 Secondes Architecture introduced a radically open approach to movement construction, where architecture itself became the dial. Composed of 354 components, the movement is fully exposed, turning structure into visual identity. From the outset, Greubel Forsey announced that this calibre would be produced for only five years and limited to 66 timepieces. Having built and delivered 55, the Atelier now concludes this chapter with a final edition of 11 timepieces. This last interpretation adds a subtle increase in contrast while preserving the original purist philosophy: the design of the timepiece is the movement itself, fully displayed and visible from all angles.

When the Tourbillon 24 Secondes Architecture was unveiled in 2022, it marked a clear departure from traditional movement construction. Rather than placing a movement inside a case, the entire project was conceived as an architectural composition – a mechanical landscape suspended in space, where each component contributes equally to function and visual structure.

Its convex, conical-frustum case construction was developed to support this idea. Measuring 47.05mm across the caseband and 45.50mm at the bezel, the titanium case integrates sapphire crystal around the full periphery, allowing the movement to remain visible not only from the dial side but also from above, below and every lateral angle. Light becomes an active element of the composition, revealing depth, shadows and surfaces throughout the movement. Around the dial opening, the engraved words Architecture, Harmonie, Innovation, Technique, Bienfacture, Passion, Science, Exclusivité express the conditions under which this timepiece was allowed to exist – the standard against which every component was measured.

At the heart of the calibre lies the inclined 24-second tourbillon, positioned at 6 o’clock and rotating once every 24 seconds at a 25° inclination. Combined with a fast rotation speed, this architecture contributes to chronometric stability while reinforcing the dynamic visual character of the timepiece. The movement comprises 354 components, including an 86-part tourbillon cage weighing only 0.38 grams, powered by three fast-rotating coaxial barrels delivering a 90-hour chronometric power reserve.

The Architecture concept was conceived around openness and purity. Polished spherical titanium bridges emerge from a frosted titanium mainplate, while the central elements appear suspended, almost detached from the movement base. Hours and minutes are indicated by large openworked hands mounted on a tripod bridge, accompanied by a small seconds display and a sector power-reserve indication. Every element is arranged to maintain visual balance while exposing the mechanics as completely as possible.

This final edition introduces a discreet evolution. The contrasts between surfaces are slightly reinforced, enhancing legibility and depth without altering the original intent. The aesthetic remains deliberately restrained: the movement is not decorated by design – it is the design. Architecture, mechanics and finishing remain inseparable, preserving the purity that defined the first edition.

Observers who looked closely may have noticed an inscription on the caseback: “Architecture 1.” Discreetly engraved, it served as a quiet indication that this architectural approach could one day be explored again in a different form.

This Tourbillon 24 Secondes Architecture therefore represents both an ending and a statement. It remains faithful to the original vision introduced in 2022 – a timepiece where the movement is fully exposed, fully legible and fully responsible for its own aesthetic identity – while offering a final, more contrasted expression before the calibre is permanently retired.

ROGER DUBUIS – EXCALIBUR Moonlight Monotourbillon Titanium - Unique Piece

 

ROGER DUBUIS – EXCALIBUR Moonlight Flying Monotourbillon Titanium 45mm Edition - Unique Piece - 2026

 

 Click, to see the large size. ▶ BIG FOTO 

The Roger Dubuis unique pieces program, unveils the Excalibur Moonlight, a watch projected into the stars.

Rarities, Roger Dubuis' program dedicated to the creation of unique timepieces, including bespoke, is now revealed to the public. Each timepiece created through the program is an act of Haute Horlogerie in its most inventive, creative, and innovative form. To illustrate the Rarities program, the Maison presents Excalibur Moonlight, a central monotourbillon that pays homage to the "Movements of the Sky" through artistic crafts.

 Click, to see the large size. ▶ BIG FOTO  

"Just for Friends," with these few words engraved on the back of his first watches, Roger Dubuis dedicated his creations to all those who appreciated his watchmaking mastery and creative genius. A community of aficionados sensitive to this visionary approach to time, understood as a selfaffirmation. 

 Click, to see the large size. ▶ BIG FOTO 

To perpetuate this singular and unifying spirit, the Roger Dubuis Maison created Rarities, a program exclusively dedicated to the production of unique pieces, including bespoke watches. Located on the third floor of the manufacture, behind a mysterious red door, this workshop brings together watchmakers, engineers, and designers, all united with the goal of bringing to life the wildest dreams of Roger Dubuis watch enthusiasts and collectors.

At the heart of Rarities, everything is possible; here reigns the exclusive spirit of exceptional watchmaking. From materials to complications, from finishes to artistic crafts, the choice is made according to the client's inspirations, who actively participates in the creative process, with only one imperative: to create unique pieces with high watchmaking content, sublimated by the expert hands of master artisans.

An innovative calibre protected by two patents

To showcase the full depth of the Rarities program, the Maison unveils the Excalibur Moonlight, an innovative piece designed to be the stage of the "Movements of the Sky," Roger Dubuis' annual theme. To embody this scenography, the Manufacture's designers and watchmakers imagined an interpretation of the celestial vault with the Moon, stars, and the twelve constellations of the zodiac revolving around a central tourbillon. Faithful to the Maison's great tradition in creating complex, inventive, and perfectly legible dials, this Excalibur Moonlight thus offers a four-level temporal vision. Reading the time becomes a pretext for astral contemplation, a link with these stars that make us dream.

Housed at the heart of the 45 mm black DLC titanium case is the Poinçon de Genève certified RD115 movement. First presented in 2022 and adapted for this new piece, this calibre is characterized by its central tourbillon. Its architecture, which positions the regulating organ at the centre of the movement, meaning there is no space for traditional hands. On this Excalibur Moonlight, the hour and minute hands are thus positioned on two rotating discs. Imagining an alternative display meant rethinking the gear train which resulted in two patents. 

 Click, to see the large size. ▶ BIG FOTO 

The first patent concerns the movement's "planetary" gear train with differential: it consists ofa more compact finishing gear train, that doesn't alter the multiplying effect between the barrel and the tourbillon cage, beating at 3 Hz. This system ensures a sufficient energy level to maintain the oscillations of the balance spring in the tourbillon throughout the 72-hour power reserve.

The second patent relates to the time-setting mechanism. Given that traditional hands have been replaced by two rotating discs mounted on ball bearings around the tourbillon, a solution was needed to disengage them during time setting. The Manufacture’s watchmakers invented a clip-release system controlled by a push-button. When activated in the S (setting) position, it releases the hand to allow time setting. By pressing the same button again, the selection lock moves to the W (winding) position, reconnecting to the mechanism’s winding system. 

Finesse of execution

This inventiveness applied to the RD115 calibre is mirrored on the dial side. The movement is topped at its periphery by a blue CVD (Chemical Vapor Deposition) treated brass flange, bearing applied rhodium-plated indexes filled with black Super-LumiNova®.

The second level is the rotating hour disc made of translucent bluish Murano-type glass, a glassware known for its elaborate manufacturing and colouring techniques. This disc offers a representation of the stars forming the twelve constellations of the zodiac with the name of each delicately written in full in luminescent paint. The same refinement of line is found on the upper bluish rotating minute disc.

Also made of translucent Murano-type glass, it is adorned with astral-inspired motifs with a luminescent representation of the moon phases. This complex construction is completed on the fourth level by an engraved appliqué reproducing the texture of the lunar surface. Positioned on the 1-minute tourbillon cage, it rotates at the rhythm of the seconds.

The astral theme of the Excalibur Moonlight also adorns the back of the watch. The translucent sapphire crystal has been laser-engraved with a multitude of dots inspired by the stars of the Milky Way, each tiny cavity hand-filled with luminescent material. In the dark, they radiate a soft green glow, like the constellations and motifs on the front.

Through this same sapphire crystal case back, the RD115 calibre reveals its architecture, reminiscent of Roger Dubuis' first models, with its cut-out bridges, here positioned in an arc. This airy construction offers an in-depth view of the meticulous work of hand-finishing executed on each of the calibre’s 283 components. In total, 19 different decorations are observed, including perlage on the main plate, drawing and anglage on the bridges, also finished with circular Côtes de Genève, graining on the wheels, satin polishing on the casing ring, and snailed finishing on the barrel. 

 Click, to see the large size. ▶ BIG FOTO  

The attention to detail also led the watchmakers to imagine a particular decoration for the barrel cover. This features various astronomical constellations in silver powdered varnish transfer on a black background. Their position can also be determined according to the owner's calendar specificities, for example, to represent them as they appeared on their birth date. A personalization that only a perfectly integrated manufacture can offer.

“When our engineering division XPL developed the Pilot’s Venturer Vertical Drive, they did not simply adapt an existing watch design for use in space. They took a blank sheet of paper and worked to define from scratch what a tool watch for astronauts would have to offer in terms of functionality, ease of operation, time display and material execution. Every single detail of this watch has been single-mindedly optimised for the unique requirements of human spaceflight and timekeeping in space. It was crucial for us to put the final watch into the experienced hands of real space professionals. After undergoing rigorous testing by our partner, Vast, the Pilot’s Venturer Vertical Drive is the first IWC watch that has received certification for spaceflight,” explains Chris Grainger-Herr, CEO of IWC Schaffhausen.

“The new space age is shaped by innovative and ambitious companies that push the boundaries of science and technology. These emerging players operate much like brands, deliberately harnessing the power of design to inspire people and spark enthusiasm for their bold visions. To reflect this, we have chosen a forward-looking, dynamic and beautifully minimalist design expression for the Pilot’s Venturer Vertical Drive. With its rounded edges and black and white colour scheme, it embodies our vision of a modern space watch and carries IWC’s tool watch legacy into the 21st century,” adds Christian Knoop, Creative Director at IWC Schaffhausen.

Designed for operation without a crown

The Pilot’s Venturer Vertical Drive boasts a matte black dial that is reduced to the absolute essentials and avoids light reflections. With highly legible markings, it displays two different times. The mission’s reference time is indicated by the central hour and minute hand, and also in 24-hour format by a dedicated hand on the outer dial scale, which runs from 00:00 to 24:00.

Click, to see the large size. ▶ BIG FOTO 

The necessity for a 24-hour display comes from the fact that a spacecraft or a space station completes an orbital cycle around the Earth roughly every 90 minutes. This means astronauts experience as many as 16 sunrises and sunsets within a 24-hour period. 

 Click, to see the large size. ▶ BIG FOTO 

To manage this rapid sequence of day and night, they adhere to GMT (Greenwich Mean Time) or UTC (Coordinated Universal Time). These formats retain the familiar 24-hour rhythm of Earth time, enabling the crew to keep a consistent routine with work and sleep times while in space.

Click, to see the large size. ▶ BIG FOTO 

The central hour and minute hands are normally synchronised with this reference time. If required, however, the hour hand can be moved in one-hour increments to display a second time zone. An astronaut in space can use this function, for example, to show the home time in any location on Earth. After returning to Earth, the second time zone feature transforms the watch into the quintessential companion for frequent flyers: with a simple turn of the bezel, it can be set to display the time at the destination of travel.

The edges of the black triangular hour and minute hands are coated with green Super-LumiNova®, while the arrow-shaped tip of the 24-hour hand glows blue in the dark. The blue second hand points to the inner scale, which features a thin ring in the same shade of blue. The colour is a nod to the horizon of the Earth as seen by astronauts from space.

Click, to see the large size. ▶ BIG FOTO 

This dual-time display is made possible by the newly engineered IWC-manufactured 32722 calibre, an efficient automatic movement with a 120-hour power reserve that includes an integrated GMT module. There is also a date indication at 3 o’clock.

Extreme robustness and performance

When ascending to space on a rocket, the engines generate powerful vibrations and astronauts experience acceleration forces of up to 4g, which is equivalent to four times the force of gravity on Earth. In space, hardware is exposed to vacuum, radiation and extreme fluctuations in temperature. Temperatures can exceed 100 °C in direct sunlight and plummet to -150 °C in the shade.

To ensure high robustness and reliable operation during all phases of a mission, the Pilot’s Venturer Vertical Drive is crafted entirely from advanced performance materials. Its case is made of white zirconium oxide ceramic. 

Click, to see the large size. ▶ BIG FOTO 

With a Vickers hardness rating second only to diamond, ceramic ranks among the hardest substances on Earth. The rotating bezel and case back are crafted from Ceratanium®. Developed by IWC, Ceratanium® combines the lightness and structural integrity of titanium with a hardness and scratch resistance similar to that of ceramic. 

Click, to see the large size. ▶ BIG FOTO  

The combination of these two materials makes the watch not only highly robust and resilient but also immune to temperature fluctuations and corrosion. The case back features an engraving that symbolically evokes a space vehicle, reflecting humanity’s curiosity and spirit of exploration.

The Pilot’s Venturer Vertical Drive is fitted with a white integrated FKM rubber strap. FKM (fluorinated rubber) offers excellent thermal insulation and is resistant to UV radiation, ensuring extreme durability.

Tested and certified for spaceflight by Vast

The Pilot’s Venturer Vertical Drive has undergone extensive type testing by IWC’s brand partner, Vast. Vast is building Haven-1, scheduled to be the world’s first commercial space station. Haven-1 will inform Haven-2, a multi-module, continuously crewed station that is the proposed successor to the International Space Station (ISS). 

 

Haven stations are state-of-theart, human-centric innovation labs for both private astronauts and government missions. For Haven-1’s inaugural mission, four crew members will embark on a short duration journey which will include opportunities to conduct advanced science, research and in-space manufacturing. Haven-1 will not support EVAs however its missions will lay the groundwork for future capabilities.

“IWC’s dedication to engineering excellence, delivering uncompromising accuracy, reliability, and astronaut-focused design, aligns perfectly with Vast’s human-centric approach to developing Haven-1. We’re thrilled to see this tool watch go from design and testing to launch,” added Max Haot, Vast CEO.

At their headquarters in Long Beach, California, engineers at Vast conducted thorough evaluations of the watch, assessing its resistance to vibrations and pressure changes, as well as the compatibility of its materials with the Haven-1 environment. 

The vibration tests, for example, exceeded the typical forces that astronauts experience during ascent. The watch was secured to a platform that generated rapid directional changes, exposing it to forces of up to 10g. After each test, the engineers verified that the watch remained intact and fully functional.

The Pilot’s Venturer Vertical Drive has successfully met all the testing criteria required for Haven-1 spaceflight environments and crew usage, earning an official certification for spaceflight from Vast. 

==================
