Why buy each?

Garmin Forerunner 570

Multi-band GPS and Elevate Gen 5 sensor

L1+L5 dual-frequency GPS for precise tracking in cities and trails, paired with Garmin's most advanced heart rate sensor — adding skin temperature monitoring over the FR265.

Built-in speaker and microphone

A first for this price tier — take phone calls, use voice assistant, and hear Bluetooth audio directly from your wrist. A meaningful upgrade over the silent FR265.

Garmin Triathlon Coach

AI-powered triathlon training plans that adapt to your swim, bike, and run fitness — a key differentiator over the FR265 for multisport athletes.

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.
