Garmin Fenix 6X Pro Solar Smartwatch Review – sport watch and offline satnav in one

At the touch of a button. The Fenix 6 Pro has a lot going for it. With offline maps and professional analysis features it focuses on preparation and follow-up of outdoor activities. You don't need to be a professional athlete in order to benefit from this sports watch. However, you do need to know how to use it, which is not as simple as it sounds given the huge amount of features and lack of a touchscreen.

A Garmin watch is no ordinary smartwatch. It is a fitness watch highly appreciated by athletes.

In addition to recording and analyzing training and exercise sessions the Swiss GPS specialist also added offline navigation to some of its watches.

The extensive map material based on OpenStreetmap data is only available on the Pro models of the Fenix 6, which is available in three different sizes: small (42 mm), medium (47 mm), and large (51 mm). Our review unit was Garmin’s current top model, the Fenix 6X Pro Solar. The Solar model includes a transparent solar-charging lens that will charge the watch outdoors in order to improve battery life.

Case and Connectivity

The plastic case is covered by a metal plate at the back and framed by a DLC-coated titan bezel (DLC = diamond-like carbon). The bezel is fixed and irrelevant for operation. The solar-charging lens is installed between the display and a layer of DX-treated Corning Gorilla Glass.

The Fenix 6X Pro Solar comes with 32 GB of storage for additional apps and widgets that can be downloaded from Garmin’s IQ store, along with maps, and music. Given that the speaker can only be used for system sounds, such as the alarm clock or the metronome, listening to music will require you to connect Bluetooth headphones. Sound effects are optionally supported by vibration if so desired. Some Fenix models come with just 64 MB of storage space, which can be filled with apps, maps and golf course data - a special feature of Garmin watches - but no music.

Incoming phone calls can be rejected with a message or answered. The latter will require you to grab your smartphone, though.

At the Fenix 6X Pro’s core are its many sensors, among others a pulse oximeter for measuring blood oxygen saturation. It also supports three different location services: GPS, GLONASS, and Galileo.

In addition to technical documentation, a short 50 cm / 19.7 inch cable for charging and data transfers is included as well.

Display and Brightness

Garmin’s Fenix series lacks a touchscreen and features a transflective (semi-transparent) memory-in-pixel display instead, which turned out to be significantly dimmer than the OLED displays on other smartwatches. On the plus side it is very energy efficient and can be easily read in both direct sunlight as well as low-light situations thanks to a backlight.

The Fenix also lacks an ambient light sensor. However, this turned out to be less of a problem than expected. While LCD and OLED displays will require major brightness adjustments when going outside/inside, an MIP display only requires a backlight in very dark situations and will thus work great with a single preconfigured brightness level.

Setup and Handling

Once charged via the connector at the back the watch can be setup without a smartphone. It will only ask for some personal data, which will remain on the watch given that a smartphone or computer is required to setup Wi-Fi. However, we would suggest pairing it with a smartphone. Once paired and connected, Garmin’s Connect app, which requires a user account, allows for comfortable configuration as well as exercise analysis and visualization.

The watch supports apps, widgets and a control menu similar to a smartphone’s quick panel. A number of widgets are preloaded by default, among others health statistics, exercise overview, and notifications. Others can be downloaded from Garmin’s IQ store.

The Fenix 6 is operated via six sturdy buttons, which can be beneficial while working out. Start, stop, long-press for launching the music player, another press to skip the current song in case your headset controls are unavailable. All that can be easily done without looking at the watch, and even with the watch hidden underneath a sleeve or gloves.

However, only a few controls are available at the touch of two or three buttons. Others, such as adjusting display brightness, require a staggering 31 clicks in addition to the adjustment itself, plus a final long press in order to return. Once you get familiar with the menu you will still require at least 14 clicks of three different buttons.

Up to seven settings can be accessed via hotkeys such as a long press of a button or a combination of buttons. Among others these include brightness, which by the way did not show up in the control’s menu during the entire review period. As plentiful as the Fenix 6’s features are, they are complicated to use. Nevertheless, we highly recommend going down the 27-clicks-long road to assign your personal hotkeys.

Software

Garmin’s smartphone app Garmin Connect offers different interfaces and features depending on the connected smartwatch. For example, when connecting to the Fenix 6X Pro Touch it displays options for playing golf, the pulse oximeter, or performance-based anaerobe thresholds that are unavailable with many other Garmin wearables.

The optional Garmin Connect IQ app is required for downloading additional watch faces, apps, and widgets. Garmin was one of the first manufacturers to not only support Deezer and Spotify but also Amazon Music. All three require an account and can be used offline after music has been downloaded over a Wi-Fi connection.

Uploading your own music onto your watch requires the Garmin Express application that is available for Windows and macOS.

Training

Most wearables will most likely not support skydiving and golf as activities, yet both can be found on Garmin’s smartwatch. The Fenix 6 Pro comes with 41,000 world-wide golf course maps preloaded onto the watch by default. In addition, it supports OpenStreetmap maps including points of interest.

One of the best features is roundtrip routing. After setting a starting point, most likely your current position, a direction, and a distance the watch will automatically calculate different routes and will provide you with directions during your activity. As great as that feature is, it is actually arduous to use. It takes an eternity to setup and is very finicky to boot – press back one too many times and you will have to start from scratch. In theory, you can also plan and adjust your route manually. Good luck doing that with the aforementioned buttons, though.

Nevertheless, this feature was one of our favorite ones because you can also use the smartphone app to plan your route. While it turned out to be somewhat finicky and required restarting from scratch because adjusting or deleting a waypoint simply failed to work it was much more comfortable nevertheless.

Once set up, you can develop a pacing strategy called PacePro which includes altitude. Using the app, you can then send both your route and your PacePro pacing strategy to the watch and include the PacePro information in the highly customizable training display watch face. In addition to lag or lead for your route it will also show current as well as suggested pace for your current section.

In our test, we were not particularly satisfied with the splits determined based on altitude differences. However, the planning tool itself and the simplicity of use were excellent. It can be fine-tuned even further than we were able to during our test period.

Exercise statistics are saved onto the watch itself, and as expected of Garmin smartwatches they are quite extensive:

The app allows for a nice visualization of your exercise analysis, as can be seen in the following screenshots.

As soon as enough exercise data has been collected it will be supplemented with additional statistics, such as exercise effects or cardiovascular fitness (VO2 max). These are then included in your long-term exercise schedule and plan. Once transferred onto the watch they will automatically pop up on their respective due days.

Battery and Battery Life

While Garmin remains suspiciously quiet regarding battery specs, the company does specify battery life for various use cases, among others:

  • Up to 21 days in smartwatch mode with activated fitness tracker and heart-rate monitor.
  • Up to 60 hours with active GPS.
  • Up to 15 hours with active GPS and music streaming.

This list illustrates the massively detrimental effect GPS and music streaming have on overall battery life, which is why it is impossible to estimate and specify battery life for mixed usage scenarios. For the sake of comparability, we tested other smartwatches, such as the Samsung Galaxy Watch Active2 or the Apple Watch Series 5, with a one-hour-long outdoor exercise session while listening to music. With the Fenix 6 Pro, battery life dropped from 16 to 10% in this test.

If exposed to around 50,000 Lux of sunlight for at least three hours a day (on a sunny day the light intensity can be up to 100,000 Lux) the solar-charging lens can increase battery life up to 24 hours per week in the abovementioned smartwatch mode, six hours in GPS mode, or one hour in GPS and music mode. A widget can display solar charging activity over the past few days, and one of the watch faces includes a graphical representation thereof. Unfortunately, we were unable to test this feature high up in the mountains as intended because the watch arrived too late. On top of that, the test would have been performed in the less-than-ideal fall weather.

Pros

+ various activities
+ customizable training displays
+ pulse oximeter
+ multiple location services
+ planning and analysis features
+ offline navigation
+ music storage
+ long battery life
+ solar charging lens

Cons

- complicated to use
- no cellular connectivity
- no speaker

Verdict

From a sports watch perspective the Fenix 6X Pro is almost impossible to beat due to its innate combination of technology and software. While it is truly fascinating that all features are readily available at the touch of a button (or multiple buttons) on your wrist, they are much more comfortable to use on your smartphone.

The Fenix 6X Pro’s possibilities are seemingly endless. Too bad they are very hard to use on the watch itself.

In everyday use the Fenix 6 turned out to be less ideal than during exercise sessions. Its massive number of features makes it immensely complicated to find even simple things during day-to-day use. The lack of a touchscreen could have been compensated for by a rotatable bezel, like on Samsung’s Galaxy Watch. Standard smartwatch features, such as displaying and answering messages, are not as smooth and usable as they are on other wearables. Even though Garmin emphasizes the watch’s fitness and exercise capabilities it should be able to handle everyday smartwatch requirements much better considering its current price of $800 (Fenix 6X Pro) or $1,000 (Fenix 6X Pro Solar). At this price, we would have also expected a built-in speaker for answering phone calls.

Unlike many techies, I didn't find my way to technology by using a C64 or something like that; I was rather fascinated by the last meter of copper wire, about which a friend on the other end of the line could be heard so crystal clear. I studied computer science and followed the development of the phone into a smartphone for many years. Currently, innovations are becoming less and less, but getting to the bottom of them remains exciting and interesting.
