Garmin Fenix 8 / 8X Training Features

7/7 training intelligence features2024$900-1100

Garmin's latest flagship outdoor watch with AMOLED display, speaker, microphone, and dive capabilities. The complete training intelligence package.

Best For

Athletes who want the absolute best Garmin makes — AMOLED display, rugged build, speaker, mic, and dive-rated waterproofing. No compromises at any price.

Our Verdict

The Fenix 8 is Garmin's statement piece. The AMOLED display is the biggest upgrade over the 7 series — menus are sharper, data fields are more readable, and the always-on mode finally looks good. Speaker and microphone enable on-wrist voice commands. Dive capability to 40 meters opens it to water sports athletes. The question is whether all of this justifies nearly double the price of a Fenix 7 Pro. For most runners and trail athletes, the 7 Pro delivers 95% of the training value at 60% of the cost.

Garmin Fenix 8 / 8X: In-Depth Review

The Fenix 8 is Garmin's flagship outdoor watch and the first Fenix to feature an AMOLED display. This is the watch for athletes who refuse to compromise on anything: display quality, durability, training data, navigation, and connected features. It is also the most expensive Garmin watch aimed at athletes rather than luxury buyers, which means the price needs justifying.

The AMOLED display is the upgrade that Fenix loyalists waited years for. Previous Fenix models used MIP displays that excelled in sunlight but looked washed out indoors and in low light. The Fenix 8's AMOLED is vibrant, sharp, and makes maps, data fields, and menus significantly easier to read in all conditions. The always-on mode finally looks good enough that you stop reaching for your phone to check the time.

Speaker and microphone add connected features that previous Fenix models lacked. On-wrist phone calls, voice commands, and audio prompts during workouts move the Fenix closer to smartwatch territory without sacrificing its identity as a training tool. These are convenience features rather than training features, but they make the Fenix 8 a more complete daily-wear device.

Dive capability rated to 40 meters opens the Fenix 8 to open water swimmers, freedivers, and recreational divers who want one device for everything. Previous Fenix models were waterproof but not dive-rated, so water sports athletes had to carry a separate dive computer.

Training intelligence is identical to other all-7 watches in practice, but the Fenix 8 benefits from the latest sensor hardware and algorithm refinements. The real question is cost-effectiveness. The Fenix 7 Pro at $600-800 delivers 95% of the training data at 60% of the price. The Forerunner 970 at $600-650 has better running-specific features in a lighter package. The Fenix 8 only makes sense if you need both AMOLED quality and Fenix-grade durability, or if the speaker, microphone, and dive features address specific use cases in your life.

Pros

  • First AMOLED Fenix - best display in any rugged Garmin watch
  • Speaker and microphone for on-wrist calls and voice control
  • Dive-rated to 40 meters for water sports versatility
  • Military-grade durability with titanium and sapphire options
  • All 7 training intelligence features with latest algorithms

Cons

  • Starting price of $900+ is hard to justify for pure training value
  • Heavier than any Forerunner (88g for AMOLED 47mm)
  • AMOLED battery life shorter than MIP Fenix 7 models
  • Fenix 7 Pro delivers similar training value at much lower cost
