Why buy each?

Garmin Forerunner 170

Training Readiness at entry level

Training Readiness, full Training Status, and wrist-based running power — analytics previously reserved for Garmin's mid-range — now on a $299.99 watch.

AMOLED display and 10-day battery

A bright 1.2" AMOLED touchscreen with a traditional 5-button design, up to 10 days of battery in smartwatch mode and around 17 hours of GPS.

Garmin Pay and 80+ sports apps

Contactless payments arrive on the entry Forerunner for the first time, alongside 80+ built-in sports apps and Garmin Coach adaptive training plans.

Suunto Vertical

AMOLED display — first for the Vertical line

The Vertical 2 replaces the MIP screen with a bright 1.5" AMOLED LTPO — delivering vivid colour maps and improved night readability while still providing 65 hours of dual-band GPS.

Built-in LED flashlight

An integrated LED flashlight is new to the Vertical 2, adding practical trail and camp utility without a separate device — especially useful for early morning and night runs.

Full offline maps, 65h GPS, AI Coach

Global topographic maps with dual-band GPS, 20-day smartwatch battery, and an AI Coach that personalises training load and recovery recommendations directly on the watch.
