The Frederique Constant Classics Moneta Moonphase is a quartz watch collection built around a moonphase display and a fluted flange inspired by a coin’s edge. The official collection material documents both 34 mm and 37 mm versions, so the title alone does not establish the size or reference of any particular watch. The available evidence is manufacturer specifications, not a firsthand test; this overview therefore sticks to documented details and flags where models differ.
What the Moneta Moonphase is
Frédérique Constant describes the collection as having “a fluted flange reminiscent of the edge of a coin, which inspired its name.” The flange is the defining visual detail; the moonphase display supplies the collection’s other prominent feature. The brand identifies the FC-206 movement as based on the Ronda 706, rather than describing it as an in-house calibre. Official Classics Moneta Moonphase collection.
The official collection pages document 34 mm and 37 mm versions. Because the title does not identify a reference, it would be misleading to assign one size, dial, or full specification set to every Moneta Moonphase.
Documented sizes and reference-specific specifications
| Version or reference | What the brand documents |
|---|---|
| 37 mm collection | Quartz-powered; the collection’s fluted flange is described as recalling a coin edge. Frédérique Constant’s video description, published September 17, 2024, describes a steel case and blue, black, or silver dial options. Collection page; official video description. |
| 34 mm collection | Official collection page documents this case size and the FC-206 movement family and moonphase concept. 34 mm collection page. |
| FC-206S3S5 | Silver-tone sunray dial; moonphase at 6 o’clock; anti-reflective convex sapphire crystal; 5M water resistance; quartz movement; and a manufacturer-stated five-year battery life. Official US product listing. |
| Other listed references | Official US listings include FC-206N3S6 and FC-206MPSAL2S4. Do not assume the FC-206S3S5 dial or specifications apply to them; consult the matching product listing. FC-206N3S6; FC-206MPSAL2S4. |
The five-year battery life is the manufacturer’s stated specification for FC-206S3S5, not an independently measured result. Likewise, the 5M water-resistance figure is specific to that reference in the cited listing.

What to verify before choosing a version
Start with the reference number, then confirm the dimensions and features on its own official product page. This avoids treating a collection-level description or one model’s specification as universal.
- Case size: choose between the documented 34 mm and 37 mm options, checking the exact reference rather than relying on the collection name.
- Dial and case details: the brand video describes blue, black, and silver dial options for the 37 mm steel-case collection; confirm the actual color and finish for the reference you are considering.
- Crystal, water resistance, and battery: the cited listing gives these details for FC-206S3S5. Verify them separately for any other reference.
- Movement description: the collection page identifies FC-206 as based on Ronda 706.
- Personal fit and operation: wrist comfort, legibility, finishing, crown feel, and ease of setting the moonphase are not established by the manufacturer specifications cited here. Assess those in person if they matter to your decision.
What this can—and cannot—tell you about wearing the watch
The documented design and specifications establish a coin-edge-inspired flange, a moonphase display, two case-size options, and quartz movement. They do not establish how the watch wears on a particular wrist, how clearly its dial reads in different lighting, or how its finishing compares with alternatives. No independent accuracy, comfort, finishing, or battery-life testing is available here, so those judgments should not be presented as hands-on findings.
