Suunto 9 Peak Pro
Suunto 9 Peak Pro is a watch from 2022, sitting in the premium band at an indicative $249.
It reads 13 of the 33 signals this comparison tracks. Nothing at all from body composition.
Those readings come from an optical heart rate sensor, an optical blood oxygen sensor, a GPS receiver, a barometer and an accelerometer. Blood oxygen is measured during sleep, not continuously through the day.
Its 21 days per charge are the 22nd longest of the 80 devices of its kind here that publish a figure. The transflective MIP screen can stay always on. Built-in GPS. Rated 100m / 10ATM, fine for swimming. It weighs 64 g. Case size 43mm. No subscription is required.
2022 ultra-thin MIP watch w/ SpO2 + baro; older gen, often discounted.

Turn a supported wearable into daily health scores
MyBodyAI reads COROS, Oura, Polar and Withings by logging in, Fitbit and Pixel Watch through Google Health, and Garmin through the Android app or a data export, then builds daily recovery, sleep, load and immune scores, a biological age estimate, and early warnings. Optional, and separate from this comparison.
This comparison is free and ad-free. One developer builds and updates it. If it saved you hours of research, a coffee is a kind way to say thanks.
