Why buy each?

Fitbit Edge

Larger AMOLED display with always-on option

A 1.34" AMOLED screen, 46% larger than the Charge 6's, with an optional always-on mode and a physical button.

Built-in GPS, ECG, and an altimeter

Multi-system GPS for phone-free runs, an ECG app for AFib checks, SpO2 and skin temperature sensing, and an altimeter for elevation.

User-replaceable battery

Up to 7 days per charge, a 5-minute top-up for about a day of use, and a battery you can replace yourself when it wears out.

OnePlus Watch

5-day Wear OS battery — finally

The dual-engine Snapdragon W5 + BES2800 co-processor architecture delivers up to 5 days in Smart Mode — 2–3× longer than most Wear OS rivals. A 10-minute charge provides a full day of use.

Dual-frequency GPS on a $329 watch

L1 + L5 dual-band GPS gives running and cycling route accuracy typically found only on $500+ sports watches — accurate to within metres even in urban canyons.

Full Wear OS 5 with Google ecosystem

Google Maps turn-by-turn navigation, Google Wallet contactless payment, and Play Store app access — plus Google Health Connect integration for the full Android wearables ecosystem.

Pick the Fitbit Edge if…

Anyone who wants a slim tracker with a screen, built-in GPS, and ECG rather than a full smartwatch. It suits Charge owners ready to upgrade, as long as they don't rely on Google Wallet payments or EDA stress scans. Works with both Android and iPhone via the Google Health app.

Android users who want full Wear OS 5 — Google Maps, Google Wallet, Play Store — with longer-than-average battery life without paying premium Galaxy Watch or Pixel Watch prices. Not for iPhone users: OnePlus Watch 3 does not support iOS.
