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..

The tourbillon has long been regarded as one of the most fascinating complications in the history of watchmaking. Moritz Grossmann now reinterprets this horological icon with two extraordinary creations: TOURBILLON Titanium and TOURBILLON Tremblage. These timepieces embody the manufactory’s philosophy of blending traditional craftsmanship with contemporary aesthetics.

The TOURBILLON Titanium combines the technical sophistication of a flying three-minute tourbillon with the modern appeal of a titanium case. Its solid silver dial, adorned with a fine grain d’orge guilloche pattern, reflects the artistry of hand-guided engraving techniques. The result is a watch that is both lightweight and visually striking, offering a perfect balance of durability and elegance.

The TOURBILLON Tremblage, on the other hand, celebrates the beauty of historical handcraft. Its warm rose-toned dial is meticulously engraved using the traditional tremblage technique, creating a unique matte texture that softens light and enhances depth. Paired with a white gold case, this model exudes timeless sophistication while showcasing the manufactory’s dedication to artisanal excellence.

Both models are powered by the hand-wound calibre 103.0, featuring a flying three-minute tourbillon and patented innovations for precision timekeeping. Every component is finished by hand, from the engraved plates to the polished screws set in gold chatons, reflecting the highest standards of Glashütte watchmaking. These creations are more than timepieces—they are works of art that unite heritage and modernity in perfect harmony.

Armin Strom extends its golden era with the One Week Skeleton Rose Gold, a new interpretation of its architectural One Week design. This fully skeletonised masterpiece reveals the depths of its mechanics, paying tribute to Mr. Armin Strom’s pioneering artistry in skeletonisation—a craft at the heart of the brand’s philosophy and heritage.

For the first time, the in-house calibre appears in a solid 18K rose gold case, enriching the collection with a warmer character. Rose gold-coloured finger bridges, hands, and applied indexes mirror the tone of the case, while a sleek black textile strap provides a refined modern contrast. Measuring 41 mm in diameter, the case remains compact and ergonomic, while its skeletonised architecture gives the watch a distinctive presence—a harmonious balance of technical craftsmanship and precious metal elegance.

Seven Days of Precision
At its heart lies the hand-wound Calibre ARM21-S, a reinterpretation of Armin Strom’s first in-house calibre. Two mainspring barrels work in series to deliver a steady flow of energy for seven days, wound by two ratchet wheels visible on the dial side—a distinctive Armin Strom signature. Operating at 3.5 Hz, the calibre ensures consistent precision and stability in daily wear.

Inspired by historical pocket watches, the conical power reserve mechanism is complemented by a 3D power reserve indicator, displaying remaining energy with exceptional clarity. Central hours and minutes keep the display symmetrical, while a skeletonised small seconds at 9 o’clock adds an engaging sense of motion.

Transparency in Gold
Every component of the Calibre ARM21-S is decorated by hand, reflecting Armin Strom’s dedication to traditional craftsmanship. Hand-polished bevels, Geneva stripes, circular graining, and finely finished screw sinks demonstrate uncompromising attention to detail. Each One Week is assembled twice—a hallmark of the brand’s commitment to mechanical precision and aesthetic integrity.

Limited to just 50 pieces worldwide, the One Week Skeleton Rose Gold continues Armin Strom’s modern gold chapter—a celebration of mechanical transparency, precision, and craft.

Chronoswiss introduces the Lunar Chronograph Aurora, a contemporary evolution of one of the brand’s most enduring icons. Since its debut in 1999, the Lunar Chronograph has symbolized Chronoswiss’s ability to blend classical Swiss watchmaking with an independent, expressive spirit. The new Aurora edition carries this legacy forward through a captivating reinterpretation rooted in light, color, and mechanical harmony.

At the heart of the transformation is its fully CVD‑coated dial, which shifts fluidly from deep green to vivid blue as light moves across its surface. Inspired by the ethereal glow of the aurora borealis, this chromatic effect gives the watch a quietly dramatic presence, making every glance feel like a changing atmospheric phenomenon. Balanced chronograph counters, a central analog date, and a poetic moon phase at 3 o’clock come together to form a composition that remains faithful to the model’s architectural heritage while embracing a distinctly modern personality.

The polished stainless‑steel case retains iconic design elements that have defined Chronoswiss for decades, including the onion crown and screwed lugs—details that reinforce the watch’s lineage and mechanical authenticity. Paired with a contemporary grey nubuck leather strap, the Lunar Chronograph Aurora combines classical provenance with renewed visual energy, offering collectors a sophisticated yet forward‑looking chronograph that bridges past and present with effortless elegance.

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.
