Fenix 8 Solar Sapphire Sport Watch fuses GPS precision with solar-powered endurance
What Our Gearhead® Experts Are Saying:
"I’ve pushed this watch through 20-mile trail runs, alpine starts, and bikepacking weekends—it never quits. The solar charging adds real longevity, and the multi-band GPS locks on even in dense forest or canyons. It’s a powerhouse tool that’s as smart as it is tough."
From the top of 14ers to 40 meters underwater, the Garmin fenix 8 Solar Sapphire Sport Watch tracks our every pursuit. The bomber build meets U.S. military standards for thermal-, shock-, and water-resistance, meaning max grit, while the dive-rated design, leakproof buttons, and sensor guard ensure pressure, submersion, rain, and sweat don't muddle our performance metrics results. Pulling power from the sun, this watch delivers up to 653 hours of tracking in max battery GPS mode, giving us all the time for activities, while maps, round-trip routing, and SatIQ tech ensure we don't get lost when getting after it.

Love it!
I’ve had my Fenix 8 for about a month. I love it, still learning new functions all the time.

Awesome watch
Have had the fenix 8 solar for about 3weeks or so and fell in love with it. I have only had to charge the watch twice which is really nice! Switched from Apple to garmin and won’t go back highly recommend

My Favorite Garmin Watch Yet
This is my fourth Garmin fitness tracker and by far my favorite one to date... the display is easy to read, the battery life is insane with the solar option, and the touch screen was an added nice touch. So many metrics available to track and deeper analysis than what I received with my fenix 5. Love the Body Battery and rich sleep analysis it provides. This watch doesn't come off my wrist... it is now an extension of me :)

Mostly Positive, but with a few drawbacks
History; I have been a loyal Garmin Fenix user since the early days of F5, which I enjoyed it tremendously same as F6, F6sPro, F7s Pro SS. So, I have purchased 2x Garmin Fenix 8, 47mm solar/MIP displays, but I had to return them both. Design: superb, best Fenix or Garmin watch to date. Definitely a big pro here. Best rugged sports watch on the market- design & functionality at its best. OS: also excellent, nice overhaul UX, not the most intuitive but easy to adapt to after a little while. Lastly, I didn’t experience any glitches. Another positive point here. Battery: yet again, another home run by Garmin. No issues to report, certainly an improvement from my Fenix 7s Pro Sapphire Solar (42 mm) There are however 2x drawbacks for me. 1. the titanium bezel scratches way too easily. I am VERY careful with all my watches (habit I picked up from wearing expensive mechanical watches like Omega, Tudor, etc)…in a week, it already picked up visible scratches. For a rugged sports watch, I would have preferred a more durable titanium version, or stainless steel would do just fine. 2. my biggest gripe however were the new inductive buttons. About 30% of the time, they didn’t register my input (ps I disabled touchscreen, so I solely relied on buttons interactions; I need a sports watch not a smart one, so if my hands are sweaty or wet, touch screen is moot). These wireless buttons also lacked tactile feedback, despite enabling the vibration feature. I have calibrated the buttons several times via Garmin Express, but to no avail. TL:DR Sadly, I returned the F8, and got an Enduro 3. The buttons are perfect, battery is superlative (best in business), MIP screen is fantastic- exactly what I needed (the lack of speaker and dive functionality on the Enduro 3 have zero effect - I don’t need an extension of my phone on my wrist, AMOLED or MicroLED colour screens…and I’m a land creature). @Garmin - you lost me from continuing w/ the Fenix line, but didn’t jump ship to Suunto, Corps or, god forbid Apple…Soo glad that you continue to make Enduro line. Not all of us want inspector gadget flashy, and admittedly somewhat useless for the most of us , like colour screens that kill battery, microphone or fancy buttons. If one needs diving…don’t you already have Descent series?
