Why buy each?

WHOOP 5.0

Screenless by design

No distractions — WHOOP tracks everything without buzzing, glowing, or asking for your attention. All data lives in the app.

Best-in-class recovery tracking

WHOOP's Recovery Score synthesises HRV, resting heart rate, sleep quality, and respiratory rate to tell you how ready your body is each day.

Charges while you wear it

The WHOOP battery pack slides onto the device and charges it without removal — no gaps in overnight sleep tracking.

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.
