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 165

AMOLED display at entry-level price

The FR165 is the first Garmin entry-level running watch with an AMOLED display — dramatically more readable than the LCD it replaces.

Full Garmin running analytics

Training load, recovery time, Body Battery, HRV status, VO2 max estimation — the same analytics found on watches costing twice as much.

11 days of battery

11 days typical use and roughly 19 hours GPS — enough for most training blocks without mid-week charging.
