Review - Garmin Fenix 8 – 47 mm - Solar - Sapphire

Solar Sapphire Power – With a Cleaner Look

The Fenix 8 Solar Sapphire model drops the red-tinted solar overlay for a discreet black solar ring, blending seamlessly with the bezel. This new solar tech is more powerful, delivering longer battery life without compromising display clarity. It’s a noticeable improvement over earlier Solar editions.

New Hardware: Built to Push Boundaries

- Microphone & speaker: Now you can take calls, use offline voice commands, and even record voice memos with GPS tagging while out on the trail. While the speaker volume could be louder, the convenience is undeniable.

- Offline Garmin Assistant: Start workouts, save waypoints, check weather—all without needing mobile signal.

- Leak-proof buttons: New fully sealed inductive buttons make this watch dive-ready and more resilient than ever.

- Revamped UI: Garmin has redesigned the interface for quicker access, better settings grouping, and improved activity tracking. It’s slick, modern, and more intuitive for new users.

Dive Capability Without the Hefty Price Tag

The Fenix 8 includes many features from Garmin’s Descent series, including:

- Auto-detection of dives

- Snorkel and freedive modes

- Depth limit of 40m (software-based)
Though not suited for technical diving, it's perfect for recreational divers and snorkellers. The addition of diving capability makes the Fenix 8 one of the most versatile outdoor watches available—without any subscription fees.

Activity Tracking & Navigation – Next-Level Performance

From trail running to alpine hikes, the Fenix 8 excels with:

- Industry-leading GPS accuracy – tested across tight cityscapes, cliffs, tunnels, and open water.

- Heart rate monitoring – comparable to a chest strap, even during intense intervals and rides.

- Improved round-trip routing – dynamically adjusts if you veer off course.

- Strength training plans – now available through Garmin Connect.

Notable Limitations

While nearly flawless in performance, the Fenix 8 does not include cellular connectivity, which may disappoint some users looking for full standalone safety features.

At £949.99+ RRP, it’s a significant investment, especially considering the price jump from the previous generation. However, its breadth of functionality arguably justifies it for serious adventurers.
