Arnold & Son presents two new evocative versions of its ultra-thin HM model, featuring dials crafted from Namibian pietersite. Often called the "stone of storms," this decorative mineral belongs to the chalcedony family and was first discovered by Sid Pieters in the early 1960s. Each unique dial displays delicate, swirling patterns that recall the turbulent skies and foaming waves of Cornwall, the English birthplace of founder John Arnold. This design pays tribute to the ingenuity of the legendary watchmaker while celebrating the spirit of those who maintain their course in a challenging world.

The designation "HM" was intentionally chosen to reflect the watch's focus on displaying only hours and minutes, while simultaneously serving as a historical nod to the British Royal Navy. In naval tradition, HM stands for "His or Her Majesty’s," a title that appeared in the 17th century and was later formalized as HMS. By transposing this reference to watchmaking, Arnold & Son connects the precision of modern horology with England's maritime history, specifically the era when John Arnold’s marine chronometers enabled the exploration of new lands.

Encased in a choice of 18-carat red gold or stainless steel, the HM Pietersite is a masterpiece of elegance and restraint. The case measures a refined 39.5 mm in diameter with a remarkably slim profile of just 7.82 mm. To complement the dreamlike, diaphanous patterns of the pietersite dial, the timepiece is paired with a matte ink-blue alligator leather strap and a traditional pin buckle crafted from the same metal as the case. These limited editions are produced in extremely small quantities, with only 8 pieces available in red gold and 18 in steel.

At the heart of this timepiece lies the ultra-thin, in-house A&S1001 manual-winding calibre. Visible through a sapphire crystal case back, the movement is a showcase of luxury finishing, featuring a rhodium-plated main plate with circular graining and bridges adorned with radiating Côtes de Genève. Despite its slender height of only 2.70 mm, the movement offers exceptional performance with a generous 90-hour power reserve. Every detail, from the snail-finished wheels to the blued screws with polished heads, reflects the most exacting standards of Swiss watchmaking.

Chronoswiss proudly presents the Delphis Art Deco, a striking new edition that bridges the design philosophy of the Roaring Twenties with modern mechanical watchmaking. Housed in a 42mm Grade 5 titanium case with a matte finish, this limited-edition timepiece pays homage to an era celebrated for its architectural clarity, geometric symmetry, and creative freedom. Combined with a black nubuck strap, the piece achieves a balanced, modern presence that elevates the emblematic Delphis complication first introduced in 1996.

At the center of the watch is a lasered, nickel-coated main dial featuring a subtle three-dimensional texture in a refined grey tone. The upper stage hosts the iconic Delphis display: a digital jumping hour at 12 o'clock, a sweeping retrograde minute hand, and a subdial at 6 o'clock. Highlighted in a captivating "Art-Deco Blue" lacquer over a hand-guilloché base engraved on century-old machines at Atelier Lucerne, the subdial is beautifully accented by a gold-plated minute ring that adds a warm, geometric contrast.

Beating inside is the manufacture automatic Caliber C.6004, developed in partnership with La Joux-Perret. Visible through the transparent sapphire crystal caseback, this 37-jewel movement delivers a 55-hour power reserve and features ruthenium-plated bridges decorated with Geneva stripes and a skeletonized tungsten rotor. The 17-piece solid titanium case incorporates Chronoswiss’s signature onion crown, patented Autobloc screw lugs, and a robust 10 bar (100m) water resistance rating.

Strictly limited to just 150 pieces worldwide, the Chronoswiss Delphis Art Deco is a sophisticated mechanical tribute to 1920s design reimagined for contemporary collectors. Blending heritage hand-craftsmanship with modern engineering, it represents a bold new chapter for one of the brand's most recognizable models. The Delphis Art Deco is now available for order through authorized Chronoswiss retailers and official channels.

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.

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..

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.
