In 2024, the Antarctique Green Meteor introduced collectors to the particular beauty of meteorite as a dial material: its Widmanstätten pattern, formed over millions of years as molten iron-nickel alloys cooled in the void of space, creates an optical illusion of infinite depth that no hand or machine can replicate. The Frozen Meteor continues this exploration, shifting the colour register from the warmth of forest green to something altogether cooler and more austere — a blue that calls to mind raw denim, polar ice at dusk, and the metallic grey of a winter sky.
From the Gibeon Crater, via GT Cadrans
The dials of both the Frozen Meteor and Antarctique S Frozen Meteor are produced by GT Cadrans, near Lausanne, from slices of the Gibeon meteorite — a mass of octahedrite iron-nickel that fell over what is now Namibia in prehistoric times, estimated at approximately 600 million years ago. Each disc must be acid-washed and polished by hand to reveal the full geometry of the Widmanstätten lines before any tinting is applied; the precise angle of those lines, determined by the plane on which the raw mass is cut, is different in every slice.
For the Frozen Meteor, the meteorite's natural silvery-grey surface has been transformed by a light blue lacquer — applied in successive layers and polished to a precise finish — that shifts in tone as the light changes angle. The denim quality of this blue is deliberate: less saturated than Czapek's Cosmic Blue, colder than a the Aqua blue tone, it resonates with the brushed surfaces of the stainless steel case in a way that feels entirely coherent. The faceted trapezoid indexes and sword-shaped hands of the Antarctique are kept to their characteristic simplicity, leaving the meteorite's crystalline architecture to carry the dial.
Because the Widmanstätten pattern is a function of natural crystal formation — not a repeatable manufacturing process — no two dials present the same geometry. Each of the 38 pieces in the 40.5mm edition, and each of the 25 in the Antarctique S, carries a dial that is genuinely singular.
A New-Generation Integrated Bracelet
The Frozen Meteor editions feature the new V2 generation of the Antarctique integrated stainless steel bracelet, produced in Switzerland by STL Swiss and RD Manufacture, two specialists whose expertise in bracelet manufacturing allow Czapek to achieve the level of geometric precision and finishing consistency the collection demands. As with dials, and certain specialised components, bracelet production requires dedicated industrial processes and tooling that for now fall outside the scope of the manufacture in La Chaux-de-Fonds, which remains focused on movement production and case manufacturing. The principle of établissage applies here as it does elsewhere: working with Switzerland's finest specialists ensures both independence and quality.
The V2 bracelet is not a stylistic revision. The design language of the Antarctique bracelet — its C-shaped polished central links and brushed outer surfaces — remains intact. What has changed is the precision of execution. Tighter machining tolerances throughout the manufacturing process produce greater consistency link to link, sharper transitions at edges and angles, and a more solid, defined feel on the wrist, with reduced play between components. Certain surfaces on the underside of the bracelet have been refined from a brushed to a satin finish, a detail that preserves the intended geometry more faithfully and improves the overall visual resolution of the piece. The bracelet is now fully disassemblable, simplifying refinishing and servicing considerably during after-sales interventions.
The clasp has been completely redesigned and is manufactured by the same Swiss suppliers responsible for the new bracelet generation. The V2 quick-change system replaces the previous rotating locking mechanism with an ergonomic push-button release operable directly with the thumb, without tools. The system is already starting to be implemented across current Antarctique S, steel and titanium models. Owners of a V1 bracelet who wish to benefit from the new system may do so by purchasing a new V2-equipped bracelet through Czapek's authorised service network at a special “owner” price.
In-House Calibre SXH5
Visible through the sapphire caseback, both models are powered by Calibre SXH5 — the first movement conceived entirely in-house by Czapek, introduced with the Antarctique collection in 2020, and still the emotional and technical signature of the line. At 30mm in diameter and 4.2mm in height, the movement holds 193 components across 28 jewels. It runs at 4 Hz (28,800 vph) via a Swiss lever escapement with a variable-inertia balance wheel regulated by four gold inertia-blocks, and delivers 60 hours of power reserve from a single barrel at a torque of 8.8 Nmm. The off-centre micro-rotor in 100% recycled 950 platinum winds bidirectionally; platinum's density ensures optimal inertia in an extremely compact footprint.
Seven skeletonised bridges — their silhouette drawn from the architecture of François Czapek's 19th-century pocket watches — arrange the gear train for maximum visual transparency. The finishing throughout is commensurate with haute horlogerie: sandblasted black bridges, straight-grained bridge flanks, open ratchets, and six hand-chamfered inward angles. Through the sapphire caseback, it reads as a composition as much as a mechanism.
Evolving the Portfolio
Alongside the launch of the Frozen Meteor editions, Czapek announces the discontinuation of the Antarctique Passage de Drake Black Ink and Ice White in both the 40.5mm and 38.5mm case sizes, with effect from June 30th.
The Passage de Drake, introduced in 2020, was among the models that established the Antarctique's identity — the flinqué "Stairway to Eternity" dial pattern, in particular, became one of the most recognised signatures in the collection. The decision to retire two of its iterations reflects Czapek's ongoing effort to maintain a focused, coherent portfolio and to preserve the long-term value of each reference for the collectors who hold them.
"Discontinuing the Black Ink and Ice White is not a decision we take lightly," says Xavier de Roquemaurel, CEO of Czapek & Cie. "These are two magnificent timepieces that are part of our history. But our responsibility to collectors is not only to create — it is also to curate. A tighter portfolio means that every reference we offer carries more weight, more intention. We would rather do fewer things well than keep references in circulation simply because they exist. The Passage de Drake will continue in other expressions; Black Ink and Ice White have earned their place in the archive."
The Czapek Antarctique Frozen Meteor (40.5mm, 38 pieces) and Antarctique S Frozen Meteor (38.5mm, 25 pieces) will available to order through Czapek authorised retailers worldwide, the boutique in Geneva, and at czapek.com. Deliveries will begin in September 2026.
