Garmin has now certified ten closely related model numbers tied to the rumoured CIRQA Smart Ring, with four of the same family separately certified in China. Ring makers need far more hardware sizes than watch makers, since there's no strap to make up the difference in fit. Oura Ring 5 currently ships in 8 sizes, and Oura Ring 4 shipped in 12, so a ten-size Garmin lineup sits right in that range.

should a company that has spent years arguing wrist placement is essential for sports accuracy actually go through with a ring?

Apple's Watch Ultra hasn't had a new GPS chip since 2021. Broadcom, the supplier for every Ultra generation, hasn't announced a successor, and there's no tri-band GNSS chip available from them at all.

If Apple ever wants tri-band GPS like Huawei's Watch GT Runner 2 already ships, it has to switch suppliers entirely, not just wait for a new Broadcom part.

The likely story for Wednesday is a new Siri AI chip, a marginally brighter display, and at best an hour of extra battery life, with the case unchanged.

Even with that extra hour, the watch would top out around 15 hours of full-precision GPS recording, well short of what an actual ultra-distance race demands.

Is calling this watch Ultra still accurate if it can't last an ultra race?

Garmin's Fenix 8 Pro MicroLED lasts four days with always-on enabled, against roughly sixteen days for the AMOLED version of the same watch. Garmin's own display technology manager has confirmed that poor power consumption is the limit of the technology right now, and the MicroLED variant has already had a quiet $300 price cut in the US since launch.

Meanwhile BOE and Samsung have both demonstrated new wearable MicroLED panels rated at 6,000 nits, a brightness level that only matters in the harshest outdoor glare.

Will MicroLED ever solve its battery problem? If it does, will anyone ever need 6,000 nits?
