Armin Strom Unveils Mirrored Force Resonance Zeitgeist 1665 – A Tribute to Horological History

OCTOBER 17 2025    |    Novelties

Armin Strom unveils the Mirrored Force Resonance Zeitgeist 1665, a creative interpretation of what a Resonance wristwatch might have looked like centuries ago. This timepiece combines historical horology with modern innovation, celebrating the brand’s milestone achievement of stable and resilient Resonance.

The Zeitgeist features a stainless steel case measuring 43 mm in diameter, paired with an 18K white gold dial in an off-center design. Inside beats the Armin Strom Manufacture Caliber ARF21_ZG, a manual-winding movement with twin-seconds and flyback functionality, offering an impressive 80-hour power reserve. Limited to just 25 pieces worldwide, this exceptional creation pays tribute to the centuries-long pursuit of chronometric consistency, a challenge first explored by Christiaan Huygens in 1665. Armin Strom solved the Resonance Fragility Problem in 2016, making this phenomenon practical for wristwatches.

Frozen Elegance: Chronoswiss Unveils the Limited-Edition Delphis Glacier

Chronoswiss is proud to unveil the Delphis Glacier, a sophisticated interpretation of eternal ice and glacial beauty. Crafted in lightweight titanium and paired with a sleek black rubber strap, this latest addition to the Delphis family merges understated elegance with the bold mechanical spirit of Chronoswiss. Frozen landscapes meet modern horology. The Delphis Glacier is housed in a 42mm Grade 5 titanium case, whose natural metallic finish reflects the quiet strength and purity of alpine glaciers. Combined with the black rubber strap, the watch achieves a refined and contemporary presence on the wrist, evoking the calm majesty of ice formations shaped over centuries by nature itself.

Mechanical Cool
At the heart of the Delphis Glacier lies an upper dial that creates the stage for the retrograde minute and jumping hour complication. The crescent is silver galvanic and features a curved hand-guillochéd surface inspired by the delicate textures of glacial ice and frozen landscapes. The subdial, a curved UFO, holds the small seconds and is finished with a blue CVD-coating with hand-guilloché craftsmanship executed inside the Atelier Lucerne. The monochromatic interplay of textures and tones creates a sophisticated composition that feels both timeless and unmistakably modern.

The Soul of Precision
The Delphis Glacier is powered by the manufacture movement C.6004, a testament to Chronoswiss dedication to precision and innovation. Beyond its visual elegance, the movement ensures outstanding functionality and reliability, transforming the Delphis Glacier into a mechanical sculpture inspired by the silent power of nature. Every detail reflects the serene beauty and resilience of Swiss glaciers. As an homage to the enduring beauty and the purity of ice, the Delphis Glacier is produced in a limited edition of only 50 pieces, making it a rare companion for collectors seeking refined modern mechanics. Discover the silence. Embrace the glacier.

Mechanical Art Transversed: Moritz Grossmann Reveals the BACKPAGE Tremblage Anniversary Edition

The year 2026 marks a historic milestone for the Moritz Grossmann manufactory in Glashütte, celebrating the 200th birthday of its visionary founder and namesake, born on March 27, 1826. A genius watchmaker, scientist, author, and the initiator of the German Watchmaking School, Grossmann profoundly shaped the craft of horology and the fate of his hometown. Rather than merely duplicating historical concepts, the modern manufactory honors his legacy by blending his cutting-edge philosophy with modern engineering. This dedication to technological perfection and exceptional aesthetics cements its place among the world's elite elite watchmakers.

To commemorate this bicentennial occasion, the brand has unveiled its fourth anniversary special edition: the BACKPAGE Tremblage. Debuting on May 19, 2026, this launch presents an exclusive mechanical showcase for collectors—featuring a massive dial opening that reveals the magnificent inner workings of the movement from the front. Crafted with a luxurious three-part platinum case, the watch conceals a subtle celebratory nod on its reverse side: a balance cock delicately engraved with "1826", the birth year of Moritz Grossmann.

At the heart of this timepiece is the hand-wound manufactory calibre 107.0, a technical tour de force that essentially stands as a mirror image of the signature calibre 100.1. To allow components like the Grossmann balance, hand-engraved balance cock, and the triple-band snailing on the ratchet wheel to be admired on the dial side instead of being hidden on the back, the entire movement architecture had to be re-engineered. An additional wheel integrated between the crown wheel and the ratchet wheel reverses the rotation of the drive train, allowing the mirrored escapement and oscillation system to run perfectly in the correct direction.

The defining aesthetic highlight of this model is its German silver dial face, treated with the historic hand-worked tremblage engraving technique. By meticulously guiding a cutter back and forth in tiny trembling movements, master artisans create a vibrant, finely granulated, and uniform matt texture. The remaining dial elements define the watch's character, offered in either an expressive violet or a captivating "blue meteor" galvanized shade, framing the hour display from 11 to 5 o'clock. Strictly limited to 12 pieces per color variant worldwide, the models are completed with matching hand-annealed steel hands and hand-stitched alligator or kudu leather straps.

Chronoswiss Celebrates 30 Years of Horological Innovation with the Opus Purple Rain Limited Edition

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.

Moritz Grossmann Presents the PERPETUAL CALENDAR

To celebrate 17 years since its rebirth in 2008, Moritz Grossmann unveils a horological milestone: the PERPETUAL CALENDAR. This grand complication embodies the brand's philosophy of timeless precision, combining traditional craftsmanship with modern innovation.

The PERPETUAL CALENDAR is engineered to automatically account for the varying lengths of months and leap years, requiring no manual correction until the year 2100. This makes it one of the most technically demanding and revered complications in fine watchmaking.

The dial is a study in symmetry and clarity. A full 1–31 date scale encircles the dial, with a cup-shaped indicator framing the current date. The month and weekday are displayed on subdials at 3 and 9 o'clock, decorated with Azurage finishing. Leap year and day/night indicators are integrated into the subdials. At 12 o'clock, a poetic moon phase display features a mother-of-pearl moon gliding across a goldstone sky.

At the heart of the watch is the newly developed Calibre 101.13, a hand-wound movement based on the 100.1 calibre with an added perpetual calendar module. It comprises 401 components — 211 for the calendar module and 190 for the base movement. The movement features optimised stopwork, an integrated manual winder, and an escape wheel bearing in the barrel bridge. The finishing adheres to traditional Glashütte standards, with untreated German silver plates, raised gold chatons, and hand-engraved details.

All calendar functions can be adjusted via recessed correctors on the case, operated with a dedicated tool. A sum corrector allows for quick synchronization of all indicators after periods of inactivity.

The PERPETUAL CALENDAR is available in three elegant variants: rose gold with argenté dial (Ref. MG-003906), rose gold with anthracite dial (Ref. MG-003907), and platinum with argenté/anthracite dial (Ref. MG-003904). Each model is paired with a hand-stitched dark brown alligator leather strap and a matching prong buckle.

Moritz Grossmann continues to honour its namesake's 19th-century legacy with a commitment to "Schönstes deutsches Handwerk" — the finest German craftsmanship. The PERPETUAL CALENDAR is a testament to this enduring vision, offering collectors a timepiece that is as poetic as it is precise.

Arnold & Son Perpetual Moon 41.5 Red Gold – Cliff Grey Edition

Arnold & Son unveils the Perpetual Moon 41.5 Cliff Grey Edition, a poetic tribute to the cliffs of Cornwall and the legacy of John Arnold, the renowned marine chronometer-maker. This limited edition of 28 pieces in 18-carat red gold reflects the brand’s deep connection to celestial navigation and English heritage.

The dial is adorned with the exclusive Stellar Rays motif, a textured pattern that plays with light through layered transparent lacquer. Its Cliff Grey tone evokes the misty British coastline, while the moon phase display—among the largest in watchmaking—glows in mother-of-pearl enhanced with Super-LumiNova. Set against a midnight-blue sky, the moon is surrounded by hand-painted constellations, Ursa Major and Cassiopeia, symbols of guidance and exploration.

The case, measuring 41.5 mm in diameter, is sculpted with refined lugs and a slim bezel that opens up the dial to its full celestial display. On the reverse, a secondary moon-phase indicator allows for precise adjustment of the moon’s age.

Inside, the manually wound A&S1512 calibre offers a 90-hour power reserve and tracks lunar cycles with remarkable precision. So accurate is its mechanism that it would take 122 years of continuous operation to accumulate a single day’s deviation from the actual lunar cycle.

Crafted entirely in-house in La Chaux-de-Fonds, the movement is finished with Geneva stripes, blued screws, and circular graining. The watch is completed with a warm grey alligator leather strap and a matching red gold pin buckle.

The Cliff Grey Edition is a refined expression of Arnold & Son’s dedication to craftsmanship, astronomy, and timeless design.

SÄNTIS BY STREHLER - The world on your wrist

Three years ago, independent watchmaker Andreas Strehler launched his new brand, Strehler, to present his philosophy and craftsmanship in a more accessible form. The first model, Sirna, was designed as an essential time‑only watch that distilled his precision, expertise, and uncompromising finishing. The second model, Säntis, takes the brand naturally into the realm of complications. Like Sirna, which was named after the town Sirnach, Säntis draws its name from the mountain near Strehler’s workshop, the highest peak of the Appenzell Alps.

World Time Concept & Crown Operation
Responding to a collector’s request and inspired by his earlier Sauterelle Heure Mondiale, Strehler created a world time watch that remains elegant, intuitive, and deeply personal. Säntis uses a Cottier‑style world time display operated entirely by a single three‑position crown—preserving design purity and simplicity. The 40 mm medical‑grade stainless‑steel case blends refinement with ergonomics and stays below 10 mm thick even with the added mechanism.

Titanium Dial & Time Zone Display
The titanium dial features a sculptural three‑dimensional texture, individually machined, engraved, and hand‑polished. Its pattern is adapted from a design created with Eric Giroud for Sirna. Surrounding it, the 24‑hour ring marks day and night and rotates once per day, aligning with a fixed city ring listing 24 time zones. Central European Time is indicated by “Strehler” rather than a city, and DST‑observing cities are marked with a sun symbol. Both the city disc and 24‑hour disc use luminous printing, with additional luminous dots along the minute track.

Colour Options, Hands & Movement
The titanium dial features a sculptural three‑dimensional texture, individually machined, engraved, and hand‑polished. Its pattern is adapted from a design created with Eric Giroud for Sirna. Surrounding it, the 24‑hour ring marks day and night and rotates once per day, aligning with a fixed city ring listing 24 time zones. Central European Time is indicated by “Strehler” rather than a city, and DST‑observing cities are marked with a sun symbol. Both the city disc and 24‑hour disc use luminous printing, with additional luminous dots along the minute track.

Strap, Presentation & Limited Production
The Säntis comes with a subtly grained brown calfskin strap with contrasting off‑white stitching, and other colours are available upon request. Its steel pin buckle is crafted in‑house, echoing the case’s lines. The watch is delivered in a beechwood box with a cognac leather travel pouch. While not limited, production is naturally restricted due to the fully in‑house manufacturing of cases, dials, hands, and movements, resulting in only 30–50 watches per year shared between Sirna and Säntis.
