PULSE One: The Modern Mechanical Heartbeat

MARCH 18 2025 | Watches and Wonders 2025

This is not just a new timepiece — it’s a statement, a revolution, a new era. The PULSE One is the first of its kind, the birth of a new family, and most importantly, the bold next step in the Chronoswiss legacy.

Designed and crafted in Lucerne, this is "Modern Mechanical" in its purest form. Known for defying convention, the watchmakers at Chronoswiss have once again pushed the boundaries of mechanical artistry. For Watches & Wonders 2025, Chronoswiss has re- visioned, re-engineered, and redefined its core DNA. The result? A full-titanium powerhouse that pulses with precision, energy, and audacity - a true mechanical marvel forged by hand.

Full Titanium Jacket
The PULSE One is a first in many ways. The 41mm Grade 5 titanium case is brand new, meticulously designed from the ground up. Sleeker. Sportier. Bolder. Every line, every curve has been reimagined—pushing Chronoswiss into uncharted territory. But we didn’t stop there.

For the first time in Chronoswiss history, an integrated titanium bracelet seamlessly fuses with the case, achieving a perfect balance of form and function. A lifeline. A surge of energy. The most fluent bracelet ever produced by the Atelier Lucerne - featuring a fully hidden butterfly clasp, polished edges, and visible screws that reflect the raw beauty of precision engineering.

A Legacy Reforged
Some things change. Some things stand eternal.

The onion crown - a beacon of Chronoswiss identity - remains steadfast. A symbol of 40 years of mechanical excellence, standing tall in the storm of contemporary watchmaking. But make no mistake: This is not evolution - This is a revolution. A new vision of the Chronoswiss DNA, built for the future, rooted in heritage.

Manufacture in Every Beat
At its heart, the ruthenium-plated Chronoswiss Manufacture Caliber C.6001 drives the PULSE One with pure mechanical force. Featuring the iconic 3D regulator setup and a spectacular retrograde second at 6 o’clock, this timepiece is a celebration of movement, rhythm, and time in motion.

Limited to just 100 pieces, the PULSE One is available in two striking variations, each a testament to Chronoswiss' relentless pursuit of modernity:

PULSE One Sand: Featuring a 4N sand-blasted & -colored dial, radiating warmth and vitality.
PULSE One Blue: Featuring a deep blue dial, evoking power, depth, and dynamism.

Each model embodies contrast and duality - where heritage collides with the future, and tradition is reborn in modernity.

A New Era
The PULSE One is titanium proof of Chronoswiss' relentless drive to rethink, redefine, and revolutionize watchmaking. Strength and lightness. Power and elegance. A material that resonates with the energy of what’s next.

Chronoswiss has never followed the expected path. The Atelier Lucerne is never static—it is bold, it is different, it is spectacular.

This is the PULSE One. This is Modern Mechanical.

The Golden Era Begins: Mirrored Force Resonance in Rose Gold

Armin Strom proudly unveils a new expression of its horological mastery with the launch of the Mirrored Force Resonance in 18K Rose Gold. This limited edition marks a significant milestone for the brand’s most iconic timepiece, blending technical innovation with timeless elegance.

A First in Rose Gold

For the first time, Armin Strom’s signature case is crafted from 18K rose gold, offering a warm and luxurious aesthetic. The 43 mm case features alternating brushed and polished finishes, enhancing its sculptural presence. Beneath the sapphire crystal, a bold black off-centre dial showcases a handcrafted sunray guilloché pattern, created using a traditional rose engine lathe. A chapter ring with circular finishing adds depth and texture, while a dark grey Alcantara strap completes the refined look.

Resonance Engineered for Performance

At the heart of this timepiece lies the Caliber ARF21, a manually wound movement that exemplifies Armin Strom’s pioneering work in resonance watchmaking. The patented Resonance Clutch Spring synchronizes two independent balance wheels, enhancing precision and chronometric stability. A pusher at 2 o’clock resets the twin seconds counters, offering a visual demonstration of the resonance mechanism’s accuracy.

Craftsmanship Without Compromise

Every surface of the movement is meticulously hand-finished, visible through sapphire crystals on both sides of the case. Techniques such as hand-beveling, black polishing, perlage, and circular graining highlight Armin Strom’s commitment to haute horology. Each watch is assembled twice to ensure mechanical integrity and flawless finishing.

Limited Edition of 15 Pieces

This exclusive release is limited to just 15 pieces, each priced at CHF 88,000. It represents a rare opportunity to own a timepiece that embodies both technical brilliance and artisanal beauty.
A Statement from Claude Greisler

“The introduction of an 18-karat rose gold case marks a significant milestone for the Mirrored Force Resonance series. This choice of material not only enhances the aesthetic appeal but also underscores our commitment to offering a diverse range of options to our clientele,” said Claude Greisler, Co-Founder and Master Watchmaker at Armin Strom.

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.

Angelus Instrument de Vitesse - 60 Seconds Flat

Instrument de Vitesse, a new opus in the La Fabrique collection, revives the golden age of timed races. This single push-piece chronograph seems to have been plucked from the dashboard of a vintage GT car. It is equipped with a single timing hand – the centre seconds hand – and can time a maximum of one minute. With its sleek and refined retro sports look, Instrument de Vitesse is intended for enthusiasts of watchmaking history and culture. Housed in a 39-mm steel case, its 4.20 mm manually wound Manufacture calibre ensures that the finished timepiece is less than 10 mm thick. Instrument de Vitesse is available with an ivory-white or ebony-black dial in two limited series of 25 timepieces each.

Appearances can sometimes be deceptive. At first glance, Instrument de Vitesse does not appear to be a classic chronograph. With its three central hands, it looks like a watch... with three hands, but the tachymeter scale running around the outer edge of the dial reveals its chronometric function. For this is a chronograph presented in its purest expression, dedicated to timing short bursts – a measuring instrument designed to take average speed readings over a maximum of 60 seconds. This, in turn, casts new light on the crown, which also acts as the chronograph’s single push-piece to set the slender centre seconds hand in motion.

HM Steel - Amber Ancient and alive

The beauty of many millennia of fossilisation. The fiery shades of conifers in autumn. The radiant translucency of resin. Baltic amber reveals the richness of life, the complexity of nature and the magic of the passing of time. This rare and challenging fossilised resin is showcased in all its splendour on HM Steel Amber. It adorns the almost bare dial, framed by an ultra-thin steel case. Arnold & Son plays a new hand and continues to innovate in the field of exceptional materials.

Arnold & Son is opening a new chapter in its collections of materials. After timepieces featuring charoite, specular hematite and even meteorite, a one-off piece from the Double Tourbillon collection played host to the glistening pale yellow hues of Baltic amber for the very first time. Difficult to source and challenging to work, it took the house several months to find the precious fossil needed to produce the 38 HM Steel Amber timepieces.
