Why buy each?

Apple Watch

Heart rate every five seconds

The new health sensing system samples heart rate every five seconds all day — 60x more often than the Series 11 — and measures HRV every five minutes.

Readiness score

A daily 0–10 readiness score combines sleep, vitals, training load, and activity to suggest how hard to push.

ECG, SpO2 and hypertension notifications

On-demand ECG, blood oxygen monitoring, sleep apnea detection, and hypertension notifications carry over from the Series 11.

Garmin Forerunner 170

Training Readiness at entry level

Training Readiness, full Training Status, and wrist-based running power — analytics previously reserved for Garmin's mid-range — now on a $299.99 watch.

AMOLED display and 10-day battery

A bright 1.2" AMOLED touchscreen with a traditional 5-button design, up to 10 days of battery in smartwatch mode and around 17 hours of GPS.

Garmin Pay and 80+ sports apps

Contactless payments arrive on the entry Forerunner for the first time, alongside 80+ built-in sports apps and Garmin Coach adaptive training plans.
