Why buy each?

Fitbit Charge

ECG and EDA stress in a slim band

Full ECG, electrodermal activity stress sensing, SpO2, and continuous heart rate in a tracker thinner than most smartwatches.

Google apps integration

Google Maps navigation, Google Wallet NFC payments, and YouTube Music controls — more useful on-device apps than any previous Charge.

7-day battery with GPS

7 days of typical use, dropping to around 30 minutes per GPS workout session before needing a charge.

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.
