AMOLED, sleep coach, multi-day battery
A polished lifestyle-and-fitness watch with an FDA-cleared single-lead ECG, strong sleep tracking, and Garmin’s comparatively open data export — wellness-only beyond the ECG.
What it measures
Optical HR, HRV, single-lead ECG, Pulse Ox/SpO2, respiration, Body Battery/stress, advanced sleep tracking with a sleep coach and nap detection, and wheelchair mode.
Regulatory status
FDA-cleared ECG app (AFib detection) in the US — enabled by firmware after launch. SpO2, sleep, and stress are wellness-only.
Validation & accuracy
Garmin’s ECG is FDA 510(k)-cleared; optical HR is well regarded for daily use, while SpO2 is wellness-grade and less reliable than dedicated oximeters.
Data control & export
Raw data: open — per-activity export (FIT, GPX, TCX, CSV) and ECG export as PDF. API: open — Garmin Health API / Connect Developer Program and Connect IQ.
Wearability & battery
Bright AMOLED touchscreen, comfortable for all-day and sleep wear, with multi-day battery. Works cross-platform (iOS and Android).
Cost & access
One-time ~$449.99. Core features free; optional Garmin Connect+ ($6.99/mo) for AI insights.
Who it serves
Health-and-fitness users who want a cleared ECG, strong sleep tracking, and portable data without phone-brand lock-in.
Who is left out or burdened
ECG is US-gated and was added post-launch; SpO2 reliability; mid-high price.
✓ Strengths
- FDA-cleared single-lead ECG (AFib)
- Open export (FIT/GPX/TCX/CSV) + ECG PDF and a developer API
- Cross-platform (iOS + Android), free core data
- Strong sleep tracking and multi-day battery
✕ Weaknesses
- ECG is US-only and was added after launch
- SpO2 is wellness-grade and less reliable
- No sleep-apnea or blood-pressure clearance
- Advanced AI insights trending toward the Connect+ paywall
52
Why this clinical score. A genuine FDA-cleared ECG/AFib lifts it above wellness-only watches, but with no sleep-apnea or BP clearance it sits mid-axis.
74
Why this empowerment score. Open export formats, a developer API, cross-platform support, and free core data make it one of the more empowering watches.
78
Why this everyday score. A capable everyday watch — AMOLED, sleep coach, multi-day battery — just shy of the flagship Fenix on breadth.
