Suunto 9 Peak Pro
Suunto 9 Peak Pro is a watch from 2022, sitting in the premium band at an indicative $249.

Its 21 days per charge are the 21st longest of the 74 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 Fitbit, Oura, Polar and Withings by logging in, and Garmin from 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. I build and update it on my own. If it saved you hours of research, a coffee genuinely makes my day.
