Garmin CIRQA Smart Ring edges closer with ten-size Brazil filing

A regulatory filing in Brazil covering ten closely related model numbers has given the clearest indication yet that Garmin is preparing a smart ring — and that the device will carry the CIRQA name already used by the company's new subscription-free smart band.

On 4 September 2026, Brazil's National Telecommunications Agency, Anatel, issued homologation 04640-26-03330 for a Garmin restricted-radiation transceiver listed under model numbers A05124, B05124, C05124, D05124, E05124, F05124, G05124, H05124, I05124, and AA5124. The manufacturer is listed as Garmin International Inc. The story was first reported by Gadgets & Wearables on 6 September 2026.

The Brazilian paperwork does not name the product as a smart ring, and Garmin has made no official announcement. But according to Gadgets & Wearables and subsequent coverage from Notebookcheck and Android Authority, ten variants filed under one homologation would be unusual for a watch — where sizing is not a factor — and is exactly the pattern you would expect if Garmin were certifying a ring in multiple sizes.

The regulatory trail that led here

The Brazil filing is the latest step in a paper trail that stretches back to mid-August. On 12 August 2026, Indonesian regulatory authorities briefly published a certificate listing a Garmin fitness device by the name "GARMIN CIRQA SMART RING" — with the word "RING" appearing directly in the model name column, not in a category field auto-populated by the system. That certificate, numbered 125338/DJID/2026, was withdrawn the following day.

The critical link between the two countries is model number AA5124. According to Wareable, that same number appears in an adjacent Indonesian certificate — fitness filing 125337/DJID/2026, issued on the same date as the withdrawn CIRQA SMART RING entry — and again in the Brazilian homologation published three weeks later. On 1 September 2026, China separately certified four related model numbers from the same family, filed by Garmin's Taiwanese entity and described only as a Bluetooth device.

Taken together, the filings across three countries point to a single product family moving through the standard pre-launch regulatory process, according to analysts tracking the listings.

What CIRQA already means

Garmin launched the CIRQA Smart Band on 21 July 2026 — its first screen-free wearable, priced at £179 in the UK. The band tracks heart rate, Body Battery, stress, Pulse Ox, skin temperature, sleep and women's health across more than 80 fitness activities, with a claimed ten-day battery life and no subscription required. It weighs 20g and comes in four colourways.

The existence of that product makes it clear that CIRQA is now a range rather than a one-off, and raises the question of which features would carry over to a ring form factor. Based on the band's capabilities, a ring version would likely focus on sleep, heart rate variability and recovery tracking — metrics where comfort and all-night wearability matter most — feeding data into Garmin Connect alongside any other Garmin device the user already owns. That is speculative, however. Garmin has confirmed nothing about the ring's sensor stack, battery life, sizing or price.

A notable change of direction

If the CIRQA Smart Ring does arrive, it would represent a meaningful shift in Garmin's stated position. At the Garmin Health Summit in Prague in 2024, VP of Fitness Joe Schrick and Senior Director of Health Engineering Scott Burgett told Wareable that the company saw little reason to chase the ring form factor, arguing the wrist would always beat the finger for serious health tracking. That position held as recently as February 2026, when Garmin's new Thailand factory was confirmed for automotive and smartwatch components — explicitly not rings. A question on Garmin's Q4 2025 earnings call about non-traditional form factors led analysts at the time to judge a ring "widely speculated but unlikely."

Why it matters for UK buyers

The smart ring market in the UK in 2026 is largely defined by two options: the Oura Ring 5 at around £399 plus a roughly £5.99-a-month membership fee, or subscription-free alternatives such as the Ultrahuman Ring Pro and the RingConn Gen 2 Air that trade on price but lack ecosystem depth. Samsung's Galaxy Ring costs £399 with no subscription and integrates with Samsung Health, but a Galaxy Ring 2 is not expected until 2027, according to the latest reports.

A CIRQA Smart Ring that syncs natively with Garmin Connect — and carries no monthly fee, as the Smart Band does — would sit in a gap the current market has not filled: a ring designed specifically for the tens of millions of people already using Garmin's platform. For runners and cyclists who want to track sleep and overnight recovery without keeping a sports watch on their wrist, that is a meaningful proposition.

No UK sterling price has been confirmed. No launch date has been confirmed. Regulatory certification can precede a product's commercial release by several months, meaning the filings establish intent rather than imminence. Garmin has not responded publicly to speculation about the device.
