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.

Fitbit Sense

Continuous EDA stress tracking

The EDA (electrodermal activity) sensor tracks physiological stress throughout the day — a feature absent from most competitors at this price.

6 months Fitbit Premium included

Comes with Fitbit Premium for advanced sleep analysis, HRV trends, stress management scores, and personalised health insights.

6-day battery, works with iPhone

Unlike Apple Watch or Galaxy Watch, Sense 2 pairs with any smartphone and runs 6 days before charging.
