COROS PACE 3

COROS PACE 3 is a watch from 2023, sitting in the budget band at an indicative $229.

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, 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 24 days per charge are the 17th longest of the 74 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. Case size 42mm. No subscription is required.

Budget lightweight running watch w/ SpO2, sleep stages, HRV; phased out by Pace 4.
