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.

Constant Force Tourbillon 11, yellow gold edition - A celebration of watchmaking ingenuity

The 41.5 mm diameter Constant Force Tourbillon 11 watch in 18-carat yellow gold, released by Arnold & Son as a limited edition of 11, is driven by a hand-wound mechanical movement. Equipped with two barrels to give a 100-hour power reserve, this timepiece was entirely developed and built at the manufacture in La Chaux-de-Fonds. It is fitted with a constant force mechanism visible on the enamel dial and is regulated by a tourbillon that can be seen on the back. The architecture of this calibre is inspired by that of the timekeeping instrument driven by the first tourbillon created by Abraham-Louis Breguet in 1808, based on a chronometer movement designed by John Arnold. This first tourbillon regulator, now in the British Museum, was given to John Roger Arnold by the Paris-based watchmaker in honour of his scientific collaboration and friendship with his father. The Constant Force Tourbillon 11 timepiece, designed to mark the end of the 260th anniversary celebrations of John Arnold’s legacy, pays tribute to the watchmaker’s ingenuity and his close association with Abraham-Louis Breguet.

The greatest watchmakers of the Age of Enlightenment often knew each other. Some of them exchanged views and appreciated each other despite language barriers and political obstacles. And this was the case with John Arnold and Abraham-Louis Breguet. These two watchmakers, undoubtedly the most productive of the second half of the 18th century, forged a friendship that nothing could shake, not even the throes of war between the two countries or the French Revolution. Aware of their respective talents, during Abraham-Louis Breguet’s frequent trips to London between 1789 and 1791, they shared their views and knowledge of the principles of timekeeping, furthering the science of timekeeping, which in their eyes definitely knew no frontiers.

A Week in Blue: The One Week Manufacture Edition Blue

Armin Strom unveils the One Week Manufacture Edition Blue, a bold evolution of its foundational calibre, now reimagined in a striking deep blue. Limited to just 100 pieces, this timepiece reflects the brand’s dedication to mechanical artistry and uncompromising craftsmanship.

A Sculptural Expression of Precision
Encased in a 41 mm stainless steel case and paired with an integrated steel bracelet, the watch features a fully openworked architecture. The traditional dial is replaced by a blue PVD-coated mainplate, creating a vivid stage for the movement’s choreography. Every component is arranged in perfect symmetry, emphasizing depth, contrast, and clarity.

Engineered for Endurance
At its core is the manual-winding Calibre ARM21, developed and assembled entirely in-house. With dual barrels in series, it delivers a full seven-day power reserve and operates at 3.5 Hz for enhanced stability. A standout feature is the three-dimensional power reserve indicator, driven by a conical gear and polished cone — a nod to traditional pocket watches.

Each movement is hand-finished to haute horlogerie standards, with Geneva stripes, polished bevels, and chamfered edges. Every piece is assembled twice, ensuring flawless performance and visual harmony.

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.

Perpetual Moon 38 Night Tide - Diamonds making waves

Waxing, gibbous, blue: the power of the moon imposes itself on the Earth and even more so, on the seas. Perpetual Moon 38 Night Tide celebrates the fluctuating pull of this celestial body on the water. A large moon disc appears over vast waves. Made of mother-of-pearl and ruthenium, they rise one after the other in a cascade of soft curves. This scene, illuminated by diamonds, celebrates the femininity, elegance and evocative power of Arnold & Son’s watchmaking.

Powerful and plentiful, the waves of Perpetual Moon 38 Night Tide herald heavy seas. In the blue of the night, the tide is at its highest, and so are the rollers. The moon, capricious and triumphant, imposes its will. The gradations of the water are topped with a sparkling foam. Beneath the peaceful light of Selene, the ocean rages on.

Arnold & Son interprets this powerfully symbolic scene through mechanisms and minerals. The astronomical moon complication of Perpetual Moon 38 Night Tide is adorned in mother-of-pearl and ruthenium: a delicate, evocative composition that fully expresses the dial-makers’ expertise. The mother-of-pearl marquetry, ruthenium crystal inlays and abundance of diamonds symbolise the painstaking care lavished on the women's collections of Switzerland’s most English brand.

Armin Strom Unveils the Tribute 1 Green: A Celebration of Nature’s Elegance

Armin Strom introduces the Tribute 1 Green, a refined dress watch that pays homage to the timeless beauty of nature. Limited to just 50 pieces, this new release brings forest-inspired tones to the brand’s most elegant collection, combining artisanal craftsmanship with modern mechanical innovation.

A Forest-Inspired Masterpiece

The Tribute 1 Green features a striking off-centre dial in forest green, adorned with a hand-engraved grain d’orge guilloché pattern and crisp white Roman numerals. A frosted subdial adds depth and texture, while the green Alcantara leather strap with off-white stitching completes the composition with understated sophistication.
