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.

Opus Dakar Sundown: A Two-Tone Symphony of Desert Sunset and Fine Skeletonized Horology

Chronoswiss has officially introduced the Opus Dakar Sundown, a striking new interpretation of the celebrated Opus Dakar that captures the fleeting magic of sunset over the desert. Housed in a distinctive 41mm two-tone case crafted from stainless steel and 18ct red gold, the timepiece masterfully blends the rugged spirit of adventure with refined luxury. The warm glow of precious metal flows seamlessly into the robust steel construction, mirroring the final golden rays dancing across endless dunes. This ultimate celebration of contrasts is beautifully completed by a sand-colored nubuck leather strap that evokes the warm tones of sunlit, weathered terrain.

At the heart of the watch beats the Chronoswiss Manufacture Caliber C.741S, a fully skeletonized automatic chronograph movement that transforms every measurement of time into a visual spectacle. Designed for legibility and visual complexity, the central chronograph seconds hand sweeps the openworked dial in harmony with a 30-minute counter at 12 o'clock and a 12-hour counter at 6 o'clock. A running small seconds display at 9 o'clock provides a constant indication of the movement's heartbeat, while a highly unique, analogue pointer date display at 3 o'clock enhances its everyday practicality.

The skeletonized, CVD-coated brown dial draws inspiration from the rich palette of the desert, where warm tones create a composition that is both timeless and adventurous. By exposing the intricate mechanics beneath the surface, every skeletonized bridge, wheel, and component directly contributes to a captivating, mechanical canvas. The hands are crafted in the elegant Breguet Losange shape and rhodium-plated to ensure striking contrast against the dark, galvanic black perlage of the base plate.

Crafted in solid 23 pieces, the 41mm case features an 18ct red gold bezel with partial knurling, a screw-down case back with a red gold coin-edge ring, and Chronoswiss’s iconic onion crown. The total weight of gold used in this exceptional construction is 21.4 grams. Offering a water resistance of 3 bar (30 meters), the watch is equipped with screw-in lugs utilizing the patented Autobloc system. For over three decades, the Opus collection has embodied the bold spirit of Chronoswiss; the Opus Dakar Sundown brilliantly reimagines this legacy, shaped by craftsmanship and illuminated by one of nature's most spectacular moments.

Timeless Precision: Greubel Forsey’s QP Balancier Redefines the Perpetual Calendar

Greubel Forsey proudly unveils the QP Balancier, a revolutionary interpretation of the perpetual calendar that merges intuitive functionality with uncompromising chronometric performance. Limited to just 22 pieces in white gold, this timepiece represents a new pinnacle in haute horlogerie.

At the heart of the QP Balancier lies Greubel Forsey’s patented Mechanical Computer, a 25-part mechanical brain that “understands” the rules of the Gregorian calendar. This innovation allows the watch to adjust instantly in either direction, restart flawlessly after months unwound, and remain programmed until February 28, 2100—all without the need for pushers or complex crown positions.

The QP Balancier integrates 12 indications—including hours, minutes, seconds, power reserve, day, date, month, leap year, day/night, 24-hour display, calendar year, and a patented function selector—into a single crown interface. This makes it the most user-friendly perpetual calendar ever created, eliminating the need for manuals or reset tools.

Aesthetically, the watch is a study in purity and harmony. Its multi-level gold dial presents calendar information in a clear, linear format, flanked by leap year and day/night indicators. The tactile feedback during quick-correction mode offers a unique sensory connection between wearer and mechanism.

Housed in a 45.1 mm white gold case, the QP Balancier features Greubel Forsey’s signature 30° inclined balance wheel, a high-mass, variable-inertia system with gold mean-time screws. The movement comprises 612 hand-finished components, including twin fast-rotating barrels that deliver a 72-hour chronometric power reserve.

With the QP Balancier, Greubel Forsey has not only redefined the perpetual calendar—it has perfected it.
