Why buy each?

Xiaomi Watch

6-day battery on Wear OS

Dual-chip design keeps the main Snapdragon W5 dormant during light tasks, dramatically extending battery life beyond any rival Wear OS watch.

Wear OS 6 with ECG and eSIM

First Wear OS 6 device on the market — with ECG monitoring, EMG gesture control, and eSIM for standalone calling.

1.54" AMOLED at a competitive price

Larger and brighter display than Galaxy Watch 8 or Pixel Watch 4, with Hasselblad-tuned health sensors, starting at around $285.

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.
