COROS NOMAD
COROS NOMAD is a watch from 2025, sitting in the mid-range band at an indicative $349.
It reads 13 of the 33 signals this comparison tracks. Full coverage of activity. Nothing at all from body composition.
By sensor class: 6 at high accuracy and 1 at consumer grade. That grade is my classification of the hardware, not a lab test. Those readings come from an optical heart rate sensor, a GPS receiver, a barometer and an accelerometer.
Its 22 days per charge are the 21st longest of the 80 devices of its kind here that publish a figure. The transflective MIP screen can stay always on. Multi-band GPS. Rated 5ATM, fine for swimming. On top of the tracking it also handles music on the device and offline maps. Case size 47.8mm. No subscription is required.
Adventure/backcountry w/ offline topo maps + voice notes; MIP, dual-freq GPS; SpO2 not listed.

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.
