Garmin has already made its big splash into the world of modern screen-free wearables with the Garmin Cirqa , but a Garmin Cirqa smart ring alternative appears to be incoming too.

The news comes from an unavoidable source of early-release information for manufacturers, regulatory agencies.

As spotted by Gadgets & Wearables , the Brazilian National Telecommunications Agency has published details on upcoming Garmin devices that are possibly part of a Garmin Cirqa smart ring family.

Such agencies don’t reveal the actual product names of these gadgets, of course, instead referring to them under product codes. It’s this pattern that suggests the listings refer to smart rings rather than other kinds of wearables, though.

10 different products are grouped together under the same family, named A05124, B05124, C05124, D05124, E05124, F05124, G05124, H05124, I05124 and AA5124. This may refer to 10 different sizes of the ring. Oura currently offers eight Ring 5 sizes on its website, while the Ultrahuman Ring Pro comes in 10 sizes.

Those ring sizes are 5-14, and could be just what is covered by these Garmin listings.

For the time being, these are simply names on a database. The listings don’t tell us much about the Garmin products, bar suggesting they exist. Where FCC filings often reveal the kinds of wireless technology present in a gadget, no such details are uncovered here.

There’s only so much to learn about smart rings, though. They typically have Bluetooth, but no Wi-Fi, mobile internet ability or GPS.

What Will A Garmin Cirqa Smart Ring Be Like?

It’s perhaps more interesting to muse on what Garmin may have to do differently for a smart ring. For example, the Garmin Cirqa band is able to largely co-opt a sensor array style seen in other Garmin watches. That clearly will not work for a smart ring because there’s much less room.

Even slimmer bands like the Garmin Vivosmart 5 are able to use a sensor array similar to that of, for example, the old Forerunner 245 .

One notable element of the Cirqa band was its relative wealth of features for a minimal design wearable, including ANT+, a temperature sensor, HR broadcast and Connected GPS. How much of that will a smart ring be able to retain? And perhaps more importantly, will Garmin be able to retain the sort of heart rate sensor accuracy it has reached with its latest watches?

An appearance at a communications agency suggests the Garmin Cirqa smart ring is likely just weeks away from an announcement. The CES tech show in January is on potential point in the calendar for a reveal, but these days Garmin has no problem announcing products on its own. The Garmin Fenix 9 was recently debuted as part of a YouTube live event, for example.
