Why buy each?

Xiaomi Smart Band 9

AMOLED always-on at under $40

Most fitness trackers at this price use basic LCD displays. The Smart Band 9 brings a vivid AMOLED always-on screen — rare at this price point.

14-day battery with health monitoring

Continuous heart rate, SpO2, stress, and sleep tracking — all running for 2 weeks before charging. Most smartwatches last 1–2 days.

Works with iPhone and Android

Full functionality on both platforms via the Mi Fitness app, including notifications, sleep analysis, and health trends.

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.
