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.

Chronoswiss Unleashes the Q-Repeater – A Chiming Masterpiece combining Legacy and Future

Time is not just seen—it is heard.

Chronoswiss presents the Q-Repeater Scream and Q-Repeater Blue Note, two extraordinary Quarter Repeater timepieces that merge the sonic beauty of timekeeping with cutting-edge mechanical architecture. The watchmakers from Lucerne have created a bold reinvention of sound, design, and independent watchmaking deeply rooted in Chronoswiss history. Housed in a Grade 5 titanium case, these 42mm skeletonized masterpieces reveal the intricate mechanisms behind their chiming complication. Every press of the 10 o’clock pusher activates the mesmerizing quarter repeater function, where hammers strike to audibly indicate the hours and quarter-hours, making time a true sensory experience. At its core lies a legacy movement, rooted in the vision of Chronoswiss founder Gerd-Rüdiger Lang. First introduced in the 1990s and exclusively produced for Chronoswiss, this legacy caliber has been taken from our archives, meticulously restored, refined, and reborn in the Atelier Lucerne, making these two timepieces an extraordinary link between the past and the future.

What the watchmakers of Lucerne have achieved here is the ultimate evolution—the heart beats with the legacy of the past, carrying its passion and memories, while the body is Modern Mechanical, engineered for the next century and beyond.

Q-Repeater Scream – A Chiming Rebel
This is not your grandfather’s repeater. The Q-Repeater Scream is a wild, untamed spectacle—combining bold design and mechanical precision unlike anything in watchmaking. The multi-level dial is a skeletonized stage and at the same time part of the movement, where CVD-coated bridges in electric blue, orange, and purple hold the Paraiba green minute ring, the floating hour, as well as the small seconds rings. At 1 o’clock, the heart of this spectacle is fully visible: the striking hammers, set to release a mechanical rock concert at the press of a button.

As you can tell by the name already, it’s not just about what you see. It’s about what you hear. Every chime is a scream of innovation, breaking free from the traditions of classical repeater watches. Even the legacy movement itself becomes part of the gig, holding the Super-LumiNova blocks and hand-guilloché bridges—one of which moves when the mechanism is activated, adding to the dynamic energy of the dial. The watchmakers of Lucerne refer to the glowing ceramic blocks as “chicken heads”, a nod to the iconic amplifier knobs found on rock concert stages—designed to crank up the sound and electrify the crowd.

Caged in 42mm of titanium, the Q-Repeater Scream is limited to just 25 pieces. As only very few of the legacy movements exist this might be the final tour of the band. Each piece is a testament to mechanical defiance and unfiltered artistry. A Quarter Repeater like no other— built for collectors who dare to embrace the wild side of watchmaking.

Q-Repeater Blue Note – The Sound of Elegance
For those who seek a symphony rather than rock n roll, the Q-Repeater Blue Note takes a more refined yet equally innovative approach. Inspired by the expressive power of jazz and blues, the navy blue CVD-coated skeletonized dial and bridges which are part of the movement, play on contrasts with a silver hour ring and luminous white Super-LumiNova markers, creating a harmonious composition of mechanics and design.

In music, a blue note is an altered pitch—intentionally deviating from the standard, creating a sound that is richer, deeper, and full of soul. One could say – the Chronoswiss way of making watches – and music. The Q-Repeater Blue Note embodies this philosophy, blending traditional watchmaking with a contemporary edge, offering a timeless yet unconventional melody of time.

Like the Scream, the Blue Note features the multi-level regulator dial, a fully visible quarter repeater mechanism, and a restored historical movement, revised and refined by thewatchmakers in Lucerne. It is a timepiece that doesn’t just mark time—it composes it.

Time Reimagined, Sound Reinvented
The Q-Repeater Scream and Q-Repeater Blue Note stand as testaments to Chronoswiss’ relentless drive to push boundaries. With only 25 pieces per model, these Quarter Repeaters are more than just rare; they are audible declarations of mechanical mastery.

This is not just a watch. It is an experience. A fusion of sound and time, crafted for those who appreciate the extraordinary. Chronoswiss has never followed the expected path. The future of independent watchmaking starts here—with a chime.

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.
