Garmin Fenix 8 Pro Launch: The Ultimate GPS Smartwatch for Outdoor Adventurers & Runners

Garmin has officially unveiled the Fenix 8 Pro, its most advanced multisport GPS smartwatch to date, launched today (3rd September 2025, 12PM BST).

Whether you’re training for your next marathon, tackling ultradistance trails, or exploring remote backcountry routes, the Fenix 8 Pro is engineered to keep you connected, safe, and performing at your best.

Key Features of the Garmin Fenix 8 Pro

1. Advanced Running Metrics

Borrowed from the new Garmin Forerunner 970, the Fenix 8 Pro introduces next-generation running analytics to the Fenix franchise, including:

• Running Economy – measure efficiency at different paces to fine-tune your form and energy output.

• Running Tolerance – track how well your body adapts to training load over time.

• Step Speed Loss – identify fatigue markers by monitoring stride efficiency during long runs.

These features are game-changers for competitive runners and endurance athletes who want precise data to improve performance.

2. Stunning AMOLED & MicroLED Displays

The Fenix 8 Pro is available with a high-resolution AMOLED display, offering vibrant visuals in any condition. For those demanding maximum brightness outdoors, Garmin is also offering a microLED version — the brightest smartwatch ever built.

The Fenix 8 Pro is the world's first smartwatch equipped with a microLED display (available through the Garmin website). It is said to achieve an impressive brightness of 4,500 nits, instead of “only” 3,000 nits like the brightest OLED smartwatches on the market. Since each subpixel consists of a tiny LED, each pixel can be dimmed individually, allowing perfect black to be displayed. The new Garmin Fenix 8 Pro microLED offers even better viewing angle stability and more vibrant colors.

3. Global Connectivity Without a Phone

For the first time, Garmin’s legendary outdoor watch comes with built-in LTE-M and satellite connectivity. That means:

• Phone-free messaging and calling anywhere in the world.

• Live tracking and updates without relying on a mobile signal.

• The ability to talk to satellites directly from your wrist — perfect for adventures far beyond mobile coverage.

4. Built-in Garmin inReach® Safety Features

The Fenix 8 Pro integrates Garmin inReach® technology directly into the watch (subscription required for some services). This includes:

• Interactive SOS: Trigger a distress signal anywhere in the world, connected to Garmin ResponseSM, a 24/7 staffed emergency coordination center.

• Two-way messaging via the Iridium® satellite network for peace of mind in remote areas.

• Global coverage for adventurers who push the boundaries, even in remote areas.
