Why buy each?

Garmin Fenix

Built-in speaker and microphone

First Fenix to include a speaker — enabling phone calls, Bluetooth audio, and voice prompts directly from the watch.

AMOLED or Solar: choose your battery priority

AMOLED for the best display at 18 days. Solar MIP for up to 48+ days in expedition conditions where charging is impossible.

Certified for diving, rated for mountains

EN13319 dive mode (up to 40m), MIL-STD-810 shock resistance, and TopoActive maps covering 100+ countries — the most capable outdoor watch in Garmin's lineup.

Xiaomi Smart Band 10

Brighter AMOLED at under $40

The Smart Band 10's 1.72" display peaks at 1500 nits — 200 nits brighter than the Band 9 — making it more readable in sunlight, all for around $40.

21-day battery with health monitoring

Continuous heart rate, SpO2, stress, and sleep tracking — all running for 3 weeks before charging. Seven more days than the already impressive Band 9.

Works with iPhone and Android

Full functionality on both platforms via the Mi Fitness app, including notifications, sleep analysis, and health trends. Bluetooth 5.4 for improved connection stability.

Quick Winner

The right pick depends on what you optimize for.
