COROS APEX 2 Pro

COROS APEX 2 Pro is a watch from 2022, sitting in the premium band at an indicative $499. It is no longer sold new. It stays in this comparison because plenty of people are still wearing one.

It reads 14 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, 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 30 days per charge are the 5th 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 46.5mm. No subscription is required.

Outgoing premium outdoor; dual-freq GPS, maps, SpO2; superseded by APEX 4.
