Those specifications make it an unusually capable package on paper, but “game-changer” is a judgment, not a result established by the available records. Two details also need care: the sources give different edition-related numbers, and they do not disclose what “Secret Alloy” is made of.
What is the Czapek Antarctique Terre Adélie Secret Alloy?
It is a 2020 variant of Czapek’s Antarctique collection, identified by its Terre Adélie Secret Alloy dial. The Grand Prix d’Horlogerie de Genève (GPHG) catalog lists a steel case, a handmade lamé dial and a folding buckle. The catalog’s use of “Secret Alloy” is a dial designation; it does not provide a material composition or explain the name.
The catalog specifies a 40.5 mm case diameter and 10.6 mm thickness. These are catalog figures, not the results of an independent measurement or fit test. The case dimensions help frame the watch’s physical presence, but they cannot establish how it will wear on a particular wrist.
What are its movement and other specifications?
GPHG describes a self-winding mechanical movement with a stated power reserve of 56 hours. Its entry lists hours, minutes, seconds and date. The text of that catalog entry does not identify a caliber, so a specific movement reference should not be inferred from it.
#1 Best Overall
- This is a precision panoramic large aperture moon phase automatic mechanical watch crafted from rare natural meteorite, designed by Swiss chief designer Etienne Ruffieux, inspired by the sun, moon, and stars. The intricately carved luminous moon changes once daily, fully showcasing the entire cycle of nature's waxing and waning phases. The watch has been honored with the Chicago Design Award for its outstanding original design.
- In-house CAL.A4610 automatic mechanical movement, bidirectional automatic winding system, 28,880 vibrations per hour, 27 ruby bearings. Exquisite perlage and geneva stripes finishing, edge chamfering process, white gold plating, and engraved gold-plated brand logo. Enhanced power reserve technology delivers an extended 80-hour power reserve (twice that of standard mechanical movements). It enables more even and gradual release of the mainspring, resulting in more precise and stable timekeeping.
- The moon phase disc in Agelocer's in-house CAL.A4610 automatic mechanical movement features a precision 31-tooth structure. It advances one segment every 22.846 hours, completing a full cycle every 29.51 days to achieve a 708.23-hour lunar cycle. (Conventional moon phase discs use a 59-tooth gear, advancing one notch every 24 hours to complete a full cycle in 29.5 days, resulting in a 708-hour lunar cycle.)
- The astronomical lunar cycle is 29.53 days (708.72 hours), meaning conventional moon phases accumulate a one-day error every 2.7 years. The Agelocer moon phase watch accumulates one day of error every 4.1 years, offering greater precision than traditional 59-tooth moon phase mechanisms.
- The dial is crafted from ultra-rare Muonionalusta iron meteorite slices, discovered in Lapland, Sweden in 1906. The unique Widmanstätten pattern of meteorite iron is a natural texture formed by the slow cooling and crystallization of iron-nickel crystals in space over millions of years.
| Specification | GPHG catalog entry |
|---|---|
| Case | Steel |
| Diameter | 40.5 mm |
| Thickness | 10.6 mm |
| Dial | Handmade lamé; identified as Secret Alloy |
| Movement | Self-winding mechanical; caliber not named in the retrieved entry |
| Power reserve | 56 hours, as stated in the catalog |
| Functions | Hours, minutes, seconds and date |
| Water resistance | 120 m, as stated in the catalog |
| Buckle | Folding |
| Bracelet/strap materials listed | Leather, steel and rubber |
The 120 m water-resistance rating is a catalog specification, not a guarantee of performance for a particular used watch. Condition, maintenance and the status of seals matter when assessing an individual example; the catalog figure alone does not establish its present water resistance.
What does “Secret Alloy” mean?
The available records identify Secret Alloy as the dial designation and describe the dial finish as handmade lamé. They do not disclose a chemical composition or establish that the dial is made from a particular alloy. It is therefore more accurate to describe it as a named dial treatment than to claim a specific metal recipe.

That distinction matters because the name can sound like a technical material specification. The sources support the finish description, but not an explanation of the underlying material or how it is manufactured.
Why do the sources give different edition-related numbers?
GPHG calls the watch a 99-piece limited series. Fratello Watches’ launch-era article discusses 218 watches in relation to Czapek’s relaunch supporters. Those figures are both attached to the model’s launch context, but the available accounts do not explain whether they describe different groups or conflict.

- Daily waterproof: 100 meters waterproof, can easily deal with emergencies, such as resistance to a small amount of hand washing, face splashes and rain, car washing, etc. But it should not be immersed in water or worn in a sauna or shower in a high temperature environment. Large temperature changes cause the shell to expand and contract internally. Shrinkage can create gaps in the rubber ring, allowing water vapor intrusion.

They should not be combined into a single production total or treated as interchangeable. If edition size is important when evaluating a particular watch, ask for documentation tied to that watch and clarify which count the seller is using.
What did it cost at launch, and what is known about buying one now?
GPHG records a launch date of May 2020 and a price of CHF 18,000 including VAT. That is the catalog’s historical listed price, not a current retail quote or a guide to today’s resale value. Current availability and pricing were not established in the sources cited here.

Christie’s documented one auction example, case number 13’653. Its listing included a certificate of authenticity, a Timelab chronometer certificate, operating instructions, strap-changing tools, additional rubber and leather straps, a presentation box and outer packaging. These are details of that particular listing, not a standard package confirmed for every watch. The auction record documents an example; it does not establish current availability, a general market valuation or the contents a buyer should expect from another seller.
GPHG lists leather, steel and rubber as bracelet or strap materials. Christie’s example had additional rubber and leather straps, but that does not prove universal compatibility, fitment or present-day availability of accessories. For a specific purchase, confirm what is included and whether the components fit the watch in question.

Does the evidence justify calling it a game-changer?
The catalog supports a combination of concrete features: a 40.5 mm steel case, a handmade lamé dial, 120 m stated water resistance and a 56-hour stated power reserve. These facts explain why the watch can attract attention, but specifications alone do not prove that it changed the market or outperformed alternatives. The sources cited here provide no independent performance test or market statistic establishing either conclusion.
A grounded assessment is that the Terre Adélie Secret Alloy is a technically specified 2020 Antarctique with a distinctive named dial, while its edition count and dial composition remain unresolved in the available accounts. Whether that makes it a “game-changer” depends on a buyer’s criteria and evidence beyond the catalog specifications.
