Garmin Enduro or Fenix 6?

As our Garmin Enduro versus Fenix 6 comparison will show, there are countless variants to choose from, especially for the latter. However, the Fenix 6X Pro Solar Edition is the most similar, also in terms of case size and display features.

First, basic features and obvious differences that result from the specs:

  • Enduro
    • 1 Case size: 51 mm (turns out bulky on narrower wrists)
    • display resolution of 280 x 280 pixels, which allows the simultaneous display of max. 8 data fields
    • comparable with Fenix 6X Pro Solar Edition
    • significantly better battery life compared to all Fenix 6 variants
    • only available with Power Glass (Solar), no sapphire crystal
    • Tracks/courses visible as such on the display, but no full-fledged maps. Thus, more difficult to orient oneself in unknown terrain.
    • turn-by-turn/point-to-point navigation
    • no maps (TopoActive/ski resort/bike maps)
    • no support for downloadable maps
    • no re-routing when leaving a route, as no maps are available on the watch
    • no Trendline Popularity Routing
    • no RoundTrip routing
    • no WLAN for synchronization with Garmin Connect
    • no integrated music storage (limited to controlling the music player on the smartphone)
  • Fenix 6 Pro variants
    • 3 case sizes (something for every wrist)
      • 42 mm (Fenix 6S Pro)
      • 47 mm (Fenix 6 Pro)
      • 51 mm (Fenix 6X Pro and Fenix 6X Pro Solar)
    • 51 mm models offer a display resolution of 280 x 280 pixels, which allows simultaneous display of max. 8 data fields instead of otherwise max. 6 data fields
    • Sapphire Edition available in any case size
    • Solar Edition available in any case size
    • WLAN integrated, thus less dependent on the smartphone
    • pre-installed Europe map as well as worldwide golf/ski/bike maps
    • Turn-by-turn navigation/point-to-point navigation
    • Trendline Popularity Routing: popular routes based on extensive Garmin Connect data from other users are highlighted on the map like a heatmap. Helpful in unfamiliar areas or to find safe routes that you don’t know yet.
    • RoundTrip routing: based on a desired distance for running or cycling activities, the watch suggests three routes that also lead back to the starting point
    • Garmin Music Streaming, internal memory for music files
  • Fenix 6 Base variants
    • 2  Housing sizes
      • 42 mm (Fenix 6S)
      • 47 mm (Fenix 6)
    • Display resolution of 260 x 260 pixels, which enables the simultaneous display of max. 6 data fields
    • only available with Corning Gorilla Glass DX, no sapphire
    • Solar Editions for every case size now available
    • no WLAN
    • no maps
    • no re-routing when leaving a route, since no maps are available on the watch
    • no Trendline Popularity Routing
    • no RoundTrip routing
    • no integrated music storage (limited to controlling the music player on the smartphone)

Which model should you choose? It’s quite simple: in the decision between Enduro or Fenix 6, there is really only one point that is important in the selection: the battery life! This is in the Enduro compared to the best Fenix 6 model (6X Pro Solar) is significantly better, so that endurance athletes or users with the desire for extremely long battery life as an important criterion are better served with it. The runtimes differ by several hours in GPS mode and by several dozen days in watch mode, see the next section.

As we will see below, users of the Fenix 6 also benefit from almost all of the newly introduced features. Therefore, the general rule is: those who can do without the great battery runtimes of the Enduro will fall back on a suitable Fenix 6 variant, because they also last for a very long time.

Users with narrower wrists or with the desire for a flatter sports watch reach for the Fenix 6S Base or Pro (42 mm) models. For all others, we recommend the Fenix 6 Base (47 mm). If one of the Pro features is important to you, choose one of the Pro variants: Fenix 6S Pro or Fenix 6 Pro. Especially if real-time maps and route corrections are important, a Pro model is advised.

As for the new, elastic UltraFit nylon wristband: since the 26mm web width wristbands on the Fenix 6 are interchangeable, the new wristbands can be used as well.

Striking differences in battery life

Let’s take a look at the battery runtimes in the Enduro or Fenix 6 comparison. These differ significantly in some cases and are decisive for the selection of one or the other.

The specified battery runtimes with solar apply at 50,000 lux. For smartwatch mode, GPS expedition mode and energy-saving watch mode, they apply to wearing the watch all day for 3 hours/day outdoors at 50,000 lux. 50,000 lux is roughly equivalent to a good, sunny day in summer with no cloud cover.

The Enduro achieves significantly better battery runtimes not only due to the solar charging function, but mainly because it has a larger battery, improved processor as well as other internal improvements.

Enduro or Fenix 6: which size fits me?

Some users are simply looking for the right size Fenix 6 depending on their preference or wrist size. Below is the comparison between the 3 available sizes.

Fenix 622 mm125–208 mm47 mm1.3″ (33,02 mm)

And the new features of the Enduro?

Whether Enduro or Fenix 6: all the newly presented features of the newer model are hardly a reason to buy the Enduro, because even the watches that have been available for longer have received almost all the features via software version 15.20 as well in the meantime. These include, for example:

  • Ultra Run App: Timer logs the time spent at the aid station while the activity continues to be recorded including GPS. In the analysis of an activity, each recovery break is detailed and comprehensible.
  • Advanced PacePro/ClimbPro features: Real-time information on current and upcoming climbs and downhills.

Trail Run VO2max

The Trail Run VO2max feature introduced with the Enduro for the Trail Run and Ultra Run sport profiles is not a distinguishing feature either, because the Fenix 6 also gets it, as several users have also confirmed in the meantime. Normally, VO2max is calculated by the watch looking at how hard the heart has to work at a pace. The new feature now analyzes the VO2max taking into account a trail and heat and altitude acclimatization and incorporates even more background data.

Ultimately, this means in practice that the watches determine the VO2max more accurately during a trail run. Among other things, this is important for features based on the VO2max, which are particularly important for training control and planning. For example, the training state feature is based on changes in training load and VO2max and provides information on the effect of training on fitness level and performance. The recovery time feature also draws on VO2max to suggest the recommended recovery time to users immediately after an activity, so that more balanced training is more trackable and overloads are less likely.

WLAN only on the Fenix 6 Pro

Only the variants of the Fenix 6 Pro offer a Wi-Fi receiver. It is missing on the base models as well as on the Enduro. The Wi-Fi receiver allows the watch to be more independent of the smartphone and to perform some tasks faster, since the slower Bluetooth can be bypassed. It is used in the following scenarios as soon as a configured WLAN connection is active:

  • Sync activities automatically with Garmin Connect
  • Sync third-party audio content
  • Automatically download and install software updates
  • after selecting workouts and training plans on Garmin Connect, they are automatically downloaded to the watch

Power Glass, sapphire glass or Gorilla Glass?

Compared to the Fenix 6, the Enduro only comes with solar charging and thus always with Power Glass, which is protected with Corning Gorilla Glass DX. Thus, sapphire glass is not available for the Enduro. Among the Fenix 6 Pro models, you can choose between sapphire glass or Corning Gorilla Glass DX. If you can’t decide, here are some important distinguishing features:

  • Sapphire glass is considered particularly scratch-resistant. Scratches on the display are thus less likely compared to Corning Gorilla Glass DX.
  • Owners of both models report that the color contrast is similarly good with a good view of the display, but that the sapphire glass can show slightly more light reflections depending on the viewing angle. This could affect readability in some cases. We have the sapphire version in our Fenix 6 test and do not feel disturbed by reflections. So far, the readability was practically always given.
