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.

Introducing the Armin Strom Gravity Equal Force Ultimate Sapphire Blue

We are thrilled to announce the launch of the Armin Strom Gravity Equal Force Ultimate Sapphire Blue, a masterpiece of Swiss horology that combines technical innovation with glacial elegance.

Design & Aesthetics

The watch features a 41 mm stainless steel case and an off-center transparent sapphire crystal dial with a subdial. The main plate, crafted by Kari Voutilainen, showcases a stunning glacial blue guilloché pattern. The color palette of silvery greys and soft blues is inspired by the serene beauty of Swiss glacial lakes. The watch is completed with a blue nubuck leather strap with ice blue stitching.

Movement & Mechanics

Powered by the proprietary Caliber ASB19, the Gravity Equal Force Ultimate Sapphire Blue is the world’s first automatic movement with a patented stop-work declutch mechanism and Geneva cross. This ensures consistent torque and precision across a 72-hour power reserve. The movement is visible through both the front and back sapphire crystals, and features hand-finished components with perlage, Geneva stripes, and circular graining.

Craftsmanship

Each watch is assembled twice to ensure reliability and refinement. Every component is hand-finished in Biel/Bienne, emphasizing traditional techniques and an open-worked design.

Brand Philosophy

Armin Strom celebrates Swiss horological tradition and innovation. Founded in 1967 and revitalized in 2009 by Claude Greisler and Serge Michel, the brand is known for exposing movement mechanics on the dial side. Their motto, “The Science of Movement,” reflects their dedication to precision and craftsmanship.

Limited Edition

The Gravity Equal Force Ultimate Sapphire Blue is limited to just 25 pieces per year, making it a truly exclusive timepiece.

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

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.

Arnold & Son Unveils Perpetual Moon 41.5 Red Gold “Year of the Horse” – A Tribute to the Fire Horse

Mystical, untamed and dazzling, the Perpetual Moon 41.5 Red Gold “Year of the Horse” follows in the footsteps of Arnold & Son’s Chinese zodiac collections. In the year spanning 2026 and 2027, the Fire Horse will set the astrological tone for connoisseurs of watchmaking and métiers d’art. To celebrate this flamboyant sign, Arnold & Son presents a limited edition of eight pieces, housed in 41.5-mm red gold cases. And while the noble animal is ever alert, it is at night that the full extent of its fiery, mysterious and incandescent nature is revealed.

A horse rears on a hill top – a commanding silhouette carved out against a star-studded sky, surrounded by the sparks of a metaphorical fire. This is Arnold & Son’s interpretation of the Fire Horse, the sign that will succeed the Wood Snake on 17 February 2026. For the sixth consecutive year, Arnold & Son is back in the saddle, drawing on the full breadth of its artistic savoir-faire. Miniature painting, three-dimensional engraving, fine stonework and the refined finishing of an astronomical moon-phase calibre: the Perpetual Moon 41.5 Red Gold “Year of the Horse” tells a tale of excellence, symbolism and vital energy.

An ardent design
Behind the expressive power of the scene, lies all of Arnold & Son’s creativity and mastery. The horse, in 18-carat red gold appliqué, is hand engraved. From hooves to mane, every muscle seems to ripple with energy. The black aventurine sky shimmers like a vast, celestial expanse, where distant stars mingle with mountainous reliefs and shadowy woodland undergrowth.

In the horse’s wake, hand-painted golden dust evokes a trail of sparks that ignite one after the other as the animal passes. These glowing flashes reflect its inner fire and untamed spirit. Touches of red and yellow Super-LumiNova, diffusing the same nocturnal shades, transform the scene as the light dims. Under the radiant mother-of-pearl moon, the horse’s majestic silhouette stands out, while the embers smoulder with new intensity. Not far away, the constellations of Cassiopeia and Ursa Major take shape on the lunar disc, completing this dual-faced, dual-display dial.

A noble pedigree
On the case back, a secondary moon-phase display enables fast, accurate setting of the lunar age. The heart of the Perpetual Moon 41.5 Red Gold “Year of the Horse”, the manual winding A&S1512 calibre, follows the lunar cycle with exceptional precision. While a true lunation lasts 29 days, 12 hours, 44 minutes and 2.8 seconds, Arnold & Son have achieved such precision that it would take 122 years for the display to drift by a single day from the actual lunar cycle, provided the watch is kept fully wound.

As for all Arnold & Son movements, the A&S1512 calibre is developed, manufactured, decorated, assembled, adjusted and cased up at the Chaux-de-Fonds manufacture. Equipped with two barrels and beating at 3 Hz, it gives the Perpetual Moon 41.5 Red Gold “Year of the Horse” a generous power reserve of 90 hours.
