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.

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.

A Star Fragment, Guardian of Time: The Grand Planetarium Eccentric Meteorite

Time and space converge in the latest masterpiece of haute horlogerie: the Grand Planetarium Eccentric Meteorite. This extraordinary timepiece is crafted from a genuine meteorite fragment—once part of an asteroid’s core, drifting through space for billions of years before falling to Earth 50,000 years ago. Now, this celestial relic has been transformed into an exceptional watch, uniting cosmic heritage with unparalleled horological innovation.

At the heart of this timepiece lies a groundbreaking complication: the Eccentric Planetarium, the only mechanical Grand Planetary Complication in the world that accurately displays all eight planets—Mercury, Venus, Earth and her Moon, Mars, Jupiter, Saturn, Uranus, and Neptune—moving in real time around the Sun. This breathtaking mechanism captures the celestial dance of our Solar System with unmatched precision, making it a true marvel of both astronomy and watchmaking.

A Celestial Fusion of Science and Art
Master watchmaker Pim Koeslag has meticulously sculpted this timepiece, ensuring that its construction reﬂects the grandeur of its cosmic origins. The meteorite case, weighing 47 grams, is carefully crafted out of a 1.09 kg space stone. This extraordinary material shaped by the universe itself, features a unique Widmanstätten pattern, formed over millions of years of slow cooling in space, making each case truly one of a kind.

The dial is a celestial spectacle in itself: crafted from aventurine glass (goldﬂuss), it mimics the night sky, complete with zodiac constellations. The Eccentric Planetarium features hand-painted planetary orbits, while the meteorite dial ring, set between Mars and Jupiter, signiﬁes the asteroid belt and contains real fragments of a martian nakhlite meteorite —a piece of another world encased within this exceptional timepiece.

A Timepiece Beyond Time
Encased in domed sapphire crystal, the 44mm meteorite case showcases the celestial ballet within. The sapphire crystal case-back reveals the movement’s intricate craftsmanship, while the dark blue hand-stitched leather strap and platinum folding clasp complete this cosmic masterpiece.

“The Grand Planetarium Eccentric Meteorite is more than a watch. It is a link between humanity and the cosmos, a way to wear the universe on your wrist,” says Pim Koeslag.

This timepiece is a tribute to time itself. From a star’s death to an asteroid’s journey, from its fall to Earth to its transformation into an exceptional watch—each second it measures is an echo of the vast cosmic history it carries.

An Exclusive, Limited Edition for Collectors
The Grand Planetarium Eccentric Meteorite is available in a strictly limited edition, with a maximum of 3 pieces, depending on the avaibility and quality of the rough meteorite material. So far, Christiaan van der Klaauw has been able to produce only 2 pieces from the available material, making this timepiece an exceptionally rare collector’s item. This extraordinary creation offers the unique opportunity to own a fragment of a star, forever marking the passage of time.

About Christiaan van der Klaauw

Greubel Forsey Unveils the Final Balancier Contemporain in Stainless Steel - A Defining Final Edition

Greubel Forsey presents the final edition of the Balancier Contemporain, marking the definitive conclusion of this iconic calibre. This timepiece is housed in a 39.6mm stainless steel case – a material that has only been used twice before in the history of the Atelier. Limited to just 33 timepieces, this edition will be built and delivered exclusively in 2025. Once complete, the Balancier Contemporain calibre will be permanently retired and will never be made again.

More than a final edition, this stainless steel interpretation is a statement of purpose – it is the rarest and most exclusive case material in the Atelier’s repertoire. Its presence here is deliberate: to honour the legacy of the Balancier Contemporain with purity, restraint, and resolve.

Compact, Yet Monumental

When it was introduced, the Balancier Contemporain redefined expectations – delivering the full Greubel Forsey experience in just 39.6mm. This final edition preserves that feat of engineering and design. Under its high-domed sapphire crystal, the gold dial reveals a rich interplay of levels, textures, and finishes. A sunburst blue hour-ring frames the composition, while a deep blue minute-circle and sectorial indications for the small seconds and power reserve create both contrast and clarity. A large visual opening draws the eye to the in-house 12.6mm balance wheel, suspended above a flat, black-polished gold plate that provides visual depth and dramatic reflection.

The movement is composed of 256 parts, each hand-finished to the highest standard. The bridges are in nickel silver, frosted and spotted by hand, with perfectly polished bevels and countersinks, straight-grained flanks, and a subtle blue treatment unique to this edition. The balance wheel bridge is flat black polished steel – one of the most demanding finishes in haute horlogerie – with hand-polished bevels that reflect light beautifully. The balance wheel itself is mounted above a flat black-polished gold plate, a surface so refined it becomes both technical and architectural.

On the movement side, a black-polished gold plate is engraved in relief with the fundamental values of Greubel Forsey – invisible to the wearer, yet finished with the same uncompromising care. Olive-domed jewels are set in gold chatons, with hand-polished countersinks that catch the light at just the right angle. Every component, visible or not, is treated with the same reverence – as if each part could stand on its own as a miniature work of art.

A Closing Statement – and a New Beginning

This is the last timepiece to carry the Balancier Contemporain calibre – but it is also the first to signal a new direction. With this final edition, Greubel Forsey opens a new chapter focused on small-diameter timepieces. Over the coming years, this creative momentum will continue to build, exploring new dimensions of mechanical expression, proportion, and elegance – all without compromise.

The Balancier Contemporain in stainless steel is a definitive conclusion – and a confident beginning.

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.
