Garmin registered ten model numbers in Brazil on the same day.

All ten sit under one homologation, which is the approval a country grants a product before anyone can sell it there. The numbers run A05124, B05124, C05124, D05124, E05124, F05124, G05124, H05124 and I05124, with AA5124 alongside them. Gadgets & Wearables found the certification at ANATEL, Brazil's telecoms regulator, and read the ten variants as sizes of the CIRQA Smart Ring. Garmin has never announced that product.

A watch fits every wrist because the strap does that job, so one body covers everyone. A ring has nothing to adjust. Every finger size is a separate piece of hardware with its own tooling and its own certification paperwork, decided long before a single unit ships. Ten of them is not an experiment.

The size count is also the hardest thing about a ring to change later. A watch maker can add a strap length whenever it wants. A ring maker cannot add a size without building, certifying and stocking another piece of hardware, which is exactly why ten of them turned up in one filing on one day. Garmin has already decided how many fingers it intends to fit, and has paid to build every one of them.

Oura is the useful comparison, because Oura has already done this at volume. The Oura Ring 5 comes in eight sizes, 6 through 13. The Ring 4 before it came in twelve, 4 through 15. Garmin's ten lands between the two.

On August 12 a Garmin device listed in Indonesia's telecoms certification database carried the name CIRQA SMART RING in plain text. It dropped off the public record shortly after. Sitting beside it was another Garmin fitness product numbered AA5124. On September 1, China certified four of the same family, C05124, E05124, G05124 and H05124, filed by Garmin's Taiwanese entity and each described as nothing more specific than a Bluetooth device.

AA5124 was next to the ring in August and inside the batch of ten in September.

Markets get certified a few at a time, and a partial batch in one country followed by the full set in another is what a launch being prepared looks like from the outside. A certification is permission to sell rather than a promise to ship.

Garmin has not announced the CIRQA Smart Ring, and there is no price and no date. What those filings establish is that ten physical versions of something exist. They are far enough along to be submitted to regulators in three countries, by a company that has never sold a ring. The Indonesian listing that named the thing outright lasted long enough to be read, and then it was gone.
