  • •You want Coros's higher-rated training watch at the same price

  • •You're invested in Polar's training platform and heart rate accuracy reputation
  • •The rating gap doesn't outweigh sticking with an ecosystem you know
The Full Story

Same titanium-and-sapphire build as the Apex 2, but with 66 hours of GPS battery life, offline maps, WiFi, and 32GB of storage. Coros pitched it as a smaller, cheaper Vertix 2, and most of that positioning still holds even with the Apex 4 now above it.

Vantage M3 brings Polar's flagship-level sensors down into a smaller, lighter case than the V3. If Polar's training and recovery tools appeal to you but the V3's price doesn't, this is the watch to look at.

*Estimated — this model's exact GPS battery life isn't published by the manufacturer. All figures are standard GPS mode, midsize case, no solar boost.

†Estimated — this model launched too recently to have an established customer rating yet.
