  4. The verdict

The Garmin Fenix 8 Solar launched in late 2025 as Garmin's flagship multisport watch. It replaces the Fenix 7 Solar with a brighter AMOLED display, dive mode, voice features, and improved solar charging. At $999, it's also Garmin's most expensive watch.

Display and usability

The AMOLED display is genuinely better than the Fenix 7's MIP (memory-in-pixel) display. Colors are vibrant, animations are smooth, and the always-on mode is useful. The trade-off: AMOLED uses more battery than MIP, so the solar charging has less headroom to extend battery life.

Battery life

In smartwatch mode, Garmin claims 16 days plus perpetual solar charging in direct sunlight. In my testing: 14 days with normal use, extended to 17 days with regular outdoor exposure. In GPS mode: 47 hours (claimed) / 42 hours (real). The solar charging adds about 5-10% per day in direct sun, which doesn't fully offset the AMOLED power draw but does help.

Cycling-specific features

For cyclists, the Fenix 8 has the same features as the Fenix 7 series: cycling power, FTP tracking, structured workouts, training load (TSS, CTL, ATL). The new addition is compatibility with Garmin's Rally power pedals (L/R balance data displayed on the watch). For most cyclists, the Fenix 8 is overkill — a Garmin Edge bike computer is more cycling-specific. But for multisport athletes, the Fenix 8 is the best single device.

The verdict

The Garmin Fenix 8 Solar is the best multisport watch on the market in 2026. The display, battery life, and feature set are unmatched. For pure cyclists, a Garmin Edge is more appropriate. For multisport athletes who swim, bike, and run, the Fenix 8 is the clear choice. The $999 price is steep but competitive with premium alternatives from COROS and Polar.
