Each part is rated on one scale for every smartwatch and band, from reviewers' accuracy tests and measured battery life where they exist, what reviewers found, specs and owner reports. It rates the product itself, not how good it is for the price.
Pros
- Heart rate almost spot-on in interval runs compared with reference devices
- GPS tracks within a few metres of other watches on runs and mountain rides
- Offline colour maps, dual-band GPS, ECG/SpO2/temperature
- Same software as the dearer Vantage V3 and Grit X2 Pro
- Lovely bright AMOLED screen
- Dual-band GPS locks fast; accurate running and cycling
- Lots of recovery and training tools
Cons
- Heart rate badly wrong on a long outdoor ride and a bit laggy indoors
- Cut corners slightly more than Apple Watch 10 / Fenix 8 between tall buildings
- Shorter GPS battery and dimmer, smaller screen than the V3
- Slow pace of new features; Flow platform feels old
- Optical heart rate lags on sudden sprints
- Garmin Fenix 8 was more precise among high-rises
- Setup long and glitchy; app is convoluted
-
DC RainmakerOct 2024
Polar's flagship software and dual-band GPS at a mid-range price; accurate in most workouts, though one long ride's heart rate fell apart and the platform is ageing.
-
T3Jan 2025
A well-rounded training watch with a bright AMOLED screen and dependable GPS and heart rate, let down by a buggy setup and thin smartwatch features.
-
Much of the pricier Vantage V3 in a cheaper body; strong for triathletes, with an app and battery that could be better.
