Why buy each?

Apple Watch

Hypertension detection

The Series 11 is the first mainstream smartwatch to offer FDA-cleared hypertension (high blood pressure) detection — a feature that could flag silent health risks.

Thinnest Apple Watch ever

At 9.7mm, the Series 11 is significantly slimmer than previous models — noticeably lighter on the wrist for all-day and sleep tracking.

ECG, SpO2 and sleep apnea detection

On-demand ECG, continuous blood oxygen monitoring, and sleep apnea detection (FDA-cleared) make this one of the most medically relevant consumer wearables available.

Garmin Forerunner 265

Multi-band GPS accuracy

L1+L5 multi-band GPS reduces position drift in urban canyons and dense forest.

Training readiness score

Daily score combining HRV status, sleep, acute load, and recovery time.

Race time predictor

Estimates finish time for 5K, 10K, half-marathon, and marathon based on current fitness.
