Why buy each?

Garmin Forerunner 165

AMOLED display at entry-level price

The FR165 is the first Garmin entry-level running watch with an AMOLED display — dramatically more readable than the LCD it replaces.

Full Garmin running analytics

Training load, recovery time, Body Battery, HRV status, VO2 max estimation — the same analytics found on watches costing twice as much.

11 days of battery

11 days typical use and roughly 19 hours GPS — enough for most training blocks without mid-week charging.

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.
