COROS PACE Pro

COROS PACE Pro is a watch from 2024, sitting in the mid-range band at an indicative $349.

It reads 14 of the 33 signals this comparison tracks. Full coverage of activity. Nothing at all from body composition.

By sensor class: 5 at high accuracy and 4 at consumer grade. That grade is my classification of the hardware, not a lab test. Those readings come from an optical heart rate sensor, ECG electrodes, an optical blood oxygen sensor, a GPS receiver, a barometer and an accelerometer. Blood oxygen is a spot reading you take yourself, not a continuous one.

Its 20 days per charge are the 24th longest of the 74 devices of its kind here that publish a figure. The AMOLED 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 46mm. No subscription is required.

AMOLED running watch w/ offline maps + SpO2; non-medical ECG sensor for HRV (no AFib); clearance ~$299.
