Wonderful watch with extraordinary scratch resistance. I highly recommend buying a cheap screen protector to not worry about its preservation at all. I have been using it for two years, and the battery still lasts three weeks despite constantly using the flashlight and working out at the gym three times a week. It's possible that the strap that comes with it could be a bit higher quality, but they are easily replaceable and cost three times less than those for Apple Watch.

Popular questions about Garmin Fenix 8 51mm
How long does the Garmin Fenix 8 43mm last?
In normal mode, the battery lasts up to 10 days on a single charge, while with GPS it lasts up to 28 hours. This is usually sufficient for daily wear and regular workouts, but precise navigation, music, and extended activities noticeably reduce battery life.Source:Specifications
Isn't 43 mm too large for a small wrist?
This is the most compact version of the Fenix 8: the 43 × 43 mm case weighs 50 g without the strap. The watch doesn’t look bulky in diameter, but its 13.8 mm thickness is still noticeable—especially if you’re used to slim fitness bands.Source:Specifications
Can you dive with them?
Yes, the Garmin Fenix 8 43mm is suitable for swimming and recreational diving: it offers 10 ATM water resistance, a depth gauge down to 40 m, and dedicated diving metrics. This significantly expands the watch’s capabilities compared with standard pool models.Source:SpecificationsExpert reviews
Can I leave my phone at home when going for a run?
You can record your route and workout without a phone: the watch has GPS, maps, and a built-in player with 32 GB of storage. However, a connected phone is required to send an alert message when an incident is detected.Source:SpecificationsExpert reviews
How does the Fenix 8 differ from the Fenix 7?
The main upgrades are an AMOLED display, a microphone and speaker, a depth gauge with diving features, and a fifth-generation heart rate sensor. The difference is especially noticeable if you need a bright display, voice control without an internet connection, or diving capabilities; for basic workouts and navigation, the difference is less significant.Source:Specifications
Aren’t they a bit too feature-rich for basic fitness?
For gym workouts, walks, and basic activity tracking, the Garmin Fenix 8 43mm may be overkill. Their strength lies in route-based workouts and various types of training load: the watches track heart rate, HRV, VO2Max, sleep, and stress, and also help with map navigation.Source:SpecificationsExpert reviews

Flagship on AMOLED
At first glance, the main change in the 8th generation of Fenix from Garmin is the debut of the AMOLED display. With it, the watch has become more juicy and bright. As in Fenix 7, you can interact with the model by touching the screen and pressing physical buttons.
The new matrix did not deprive Fenix 8 of its main advantage - autonomy. In normal scenarios, you will need to connect to a socket about once a month (every 29 days). With constantly active GPS, the watch will work for more than 3 days, which is also better than competitors from Apple or Samsung. And if you want more autonomy, then the Solar version with a solar panel will suit you: by the way, it remained faithful to the traditions of Fenix and has a transflective screen.
New equipment and familiar functions
The watch has an updated heart rate sensor with a pulse oximeter function. It has become even more accurate and can now perform an ECG - this function is debuting at Garmin. A microphone and speaker have been added to the watch, so it is possible to receive calls from a paired smartphone, as well as give commands by voice, including in offline mode (when the mobile is not connected). There is also a depth gauge and readiness for amateur diving up to 40 meters is declared.
The traditional strengths remain unchanged: there is a functional and accurate GPS with track guidance, a full-fledged flashlight, support for ANT+ and Garmin Pay contactless payments, there is a built-in player and, probably, the most advanced sports functions on the market. In addition to collecting all the data on physical activity, the model prepares morning countdowns, offers workouts for every day, gives recommendations for recovery and much more.
As always, durable and waterproof
The watch is made in a shockproof plastic case (according to the MIL-STD-810 standard) and is complemented by a metal bezel (there are steel and titanium variations). Excellent tightness is supported by 100 WR water resistance. And the display is protected by either Gorilla Glass or sapphire (the latter version will cost a little more).
The price tag of the model corresponds to the flagship status, which is a minus of Garmin Fenix 8. But if you want an uncompromising solution compatible with both iPhone and Android, then the watch is definitely worth considering. And if you have a limited budget, you can take a closer look at the simplified version of Fenix E.
