The Full Story

Ultra 3 stretches Apple Watch battery life further than any other model and adds genuine durability for outdoor use. It's still not a training-analytics powerhouse next to Garmin or Coros, but as an everyday smartwatch that can also handle long runs, it's excellent.

The Fenix 9 pushes display brightness to 3,000 nits while slimming down the overall profile with a full titanium bezel and rear cover. Adding 64GB of storage, 3D topo mapping, and dedicated rucking and endurance stamina metrics, it sits right at the top of Garmin's multi-sport lineup.

*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.
