Suunto Ocean
Suunto Ocean is a watch from 2024, sitting in the flagship band at an indicative $899.
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 26 days per charge are the 14th longest of the 74 devices of its kind here that publish a figure. The AMOLED screen can stay always on. Multi-band GPS. Rated 100m; dive computer to 60m (EN13319), fine for swimming. It weighs 99 g. On top of the tracking it also handles offline maps. Case size 50mm. No subscription is required.
2024 dive computer + GPS watch (60m, Buhlmann); AMOLED, dual-band GNSS, SpO2.

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.
