fenix 8 Pro (AMOLED, 47mm)

Garmin fenix 8 Pro (AMOLED, 47mm) is a watch from 2025, sitting in the flagship band at an indicative $1199.

It reads 21 of the 33 signals this comparison tracks. Full coverage of activity. Nothing at all from body composition. Rarer readings it does take: AFib detection, ECG recording and Body Battery.

By sensor class: 11 at high accuracy and 3 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 skin temperature sensor, a GPS receiver, a barometer and an accelerometer. It records an ECG and screens for atrial fibrillation. Those are screening features, not a diagnosis. Blood oxygen is a spot reading you take yourself, not a continuous one.

Its 15 days per charge are the 38th longest of the 76 devices of its kind here that publish a figure. The AMOLED screen can stay always on. Multi-band GPS. Rated 10ATM + 40m dive (EN13319), fine for swimming. It weighs 77 g. On top of the tracking it also handles music on the device, contactless payments, its own LTE connection and offline maps. Case size 47mm. A Garmin Connected (LTE and satellite) subscription is required to use it.

September 2025 flagship above the fenix 8, first Garmin watch with built-in LTE-M and inReach satellite messaging. Same measured health signals as the fenix 8.
