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..

In the world of independent watchmaking, few designs capture the essence of mechanical artistry and thematic storytelling like the Chronoswiss Strike Two collection. With its signature horizontal regulator layout and exposed gear architecture, the collection is a canvas for both cosmic inspiration and historical homage. The Stellar Blue and Nugget editions, though forged from different visions, share a unified spirit: precision in motion, elevated by craftsmanship.

Architecture of Time

At the heart of both models lies the Chronoswiss Manufacture Caliber C.6000, developed in collaboration with La Joux-Perret. This automatic movement delivers a robust 55-hour power reserve, beating at 4 Hz (28,800 A/h). A skeletonized tungsten rotor, ruthenium-plated Geneva-cut bridges, and polished components reflect the brand’s commitment to mechanical transparency and refinement. Viewed through a sapphire caseback, the movement reveals a radial geometry that echoes the symmetry of the dial above.

The horizontal regulator layout defines the Strike Two identity: a floating hour display at 3 o’clock, central luminous minutes, and a small seconds subdial at 9 o’clock. Two architectural bridges span the dial, exposing the gear train and anchoring the visual rhythm of the watch.

Stellar Blue – A Tribute to Cosmic Velocity

The Stellar Blue edition draws inspiration from the brilliance and motion of stellar light. Its dial features a deep blue CVD-coated base, hand-guillochéd with linear engraving that mimics the trajectory of light through space. A silver rhodium-plated subdial adds contrast, while the luminous minute hand glides across the dial like a comet in orbit.

Encased in matte grey sandblasted stainless steel, the watch offers a futuristic silhouette that complements its celestial theme. Measuring 40 mm in diameter and 12.7 mm in thickness, it wears with elegance and presence. The strap is crafted from white nubuck calfskin leather, lined with blue Alcantara, echoing the dial’s cosmic hue.

Nugget – A Homage to Discovery and Rarity

In contrast, the Strike Two Nugget is a celebration of terrestrial treasure — a mechanical gold rush forged in solid 18ct red gold. Inspired by the thrill of unearthing something precious, the Nugget edition elevates the Strike Two architecture with warmth, weight, and richness.

Its anthracite dial, hand-guillochéd and treated with a galvanic finish, reveals depth and texture. A glossy white lacquered small seconds subdial punctuates the monochrome palette, while the exposed gearwork beneath the hour display adds mechanical drama.

The case, polished and sandblasted, retains the 40 mm diameter and 12.7 mm thickness, but its golden sheen transforms the watch into a statement of rarity. Paired with a black nubuck calfskin strap lined in blue Alcantara, the Nugget balances boldness with refinement..

Two Visions, One Philosophy

Whether inspired by the stars or the soil, the Strike Two Stellar Blue and Strike Two Nugget embody Chronoswiss’s philosophy of independent design, mechanical excellence, and thematic storytelling. Limited to 100 pieces each, these timepieces are not just instruments of time — they are expressions of discovery, crafted for collectors who seek meaning in every detail.

Chronoswiss celebrates three decades of horological mastery with the launch of the Opus Purple Rain, a bold and limited edition chronograph that reimagines the brand’s iconic skeletonized timepiece. Limited to just 30 pieces worldwide, this anniversary edition marks a milestone in modern independent watchmaking, honoring the legacy of the original Opus while pushing the boundaries of design and mechanical transparency.

First introduced in 1995 by Chronoswiss founder Gerd-Rüdiger Lang, the Opus revolutionized the chronograph landscape by exposing its intricate movement architecture on the dial side—a radical departure from the traditionally closed and utilitarian chronographs of the time. The Opus became a symbol of mechanical artistry and a signature of the brand’s avant-garde spirit.

The Opus Purple Rain carries this legacy into the future with unapologetic flair. Encased in Grade 5 titanium and finished with a radiant purple CVD coating, the watch is both lightweight and visually arresting. Its skeletonized dial, also rendered in ultraviolet hues, reveals the ruthenium-coated Chronoswiss C.741S automatic chronograph caliber, offering a 46-hour power reserve and a full suite of chronograph functions including central seconds, 30-minute and 12-hour counters, small seconds, and date.

Adding to its rebellious character is a white UV-reactive leather strap that transforms into glowing purple when exposed to sunlight—an unexpected and surreal tribute to the energy behind this creation. Signature Chronoswiss elements such as the onion crown, coin-edged bezel, and patented Autobloc screw-in lugs remain intact, anchoring the watch in its heritage while embracing a futuristic aesthetic.

“The Opus Purple Rain is not just a commemorative piece—it’s a statement,” said Chronoswiss CEO Oliver Ebstein. “It embodies the spirit of mechanical transparency and innovation that has defined Chronoswiss for 30 years. This is a watch for those who dare to see how far precision and design can be pushed.”

With only 30 pieces produced, the Opus Purple Rain is destined to become a collector’s treasure—a celebration of the past, a vision of the future, and a mechanical theatre on the wrist.

Greubel Forsey presents the final edition of the Balancier Contemporain, marking the definitive conclusion of this iconic calibre. This timepiece is housed in a 39.6mm stainless steel case – a material that has only been used twice before in the history of the Atelier. Limited to just 33 timepieces, this edition will be built and delivered exclusively in 2025. Once complete, the Balancier Contemporain calibre will be permanently retired and will never be made again.

More than a final edition, this stainless steel interpretation is a statement of purpose – it is the rarest and most exclusive case material in the Atelier’s repertoire. Its presence here is deliberate: to honour the legacy of the Balancier Contemporain with purity, restraint, and resolve.

Compact, Yet Monumental

When it was introduced, the Balancier Contemporain redefined expectations – delivering the full Greubel Forsey experience in just 39.6mm. This final edition preserves that feat of engineering and design. Under its high-domed sapphire crystal, the gold dial reveals a rich interplay of levels, textures, and finishes. A sunburst blue hour-ring frames the composition, while a deep blue minute-circle and sectorial indications for the small seconds and power reserve create both contrast and clarity. A large visual opening draws the eye to the in-house 12.6mm balance wheel, suspended above a flat, black-polished gold plate that provides visual depth and dramatic reflection.

The movement is composed of 256 parts, each hand-finished to the highest standard. The bridges are in nickel silver, frosted and spotted by hand, with perfectly polished bevels and countersinks, straight-grained flanks, and a subtle blue treatment unique to this edition. The balance wheel bridge is flat black polished steel – one of the most demanding finishes in haute horlogerie – with hand-polished bevels that reflect light beautifully. The balance wheel itself is mounted above a flat black-polished gold plate, a surface so refined it becomes both technical and architectural.

On the movement side, a black-polished gold plate is engraved in relief with the fundamental values of Greubel Forsey – invisible to the wearer, yet finished with the same uncompromising care. Olive-domed jewels are set in gold chatons, with hand-polished countersinks that catch the light at just the right angle. Every component, visible or not, is treated with the same reverence – as if each part could stand on its own as a miniature work of art.

A Closing Statement – and a New Beginning

This is the last timepiece to carry the Balancier Contemporain calibre – but it is also the first to signal a new direction. With this final edition, Greubel Forsey opens a new chapter focused on small-diameter timepieces. Over the coming years, this creative momentum will continue to build, exploring new dimensions of mechanical expression, proportion, and elegance – all without compromise.

The Balancier Contemporain in stainless steel is a definitive conclusion – and a confident beginning.
