Garmin Fenix 6S Pro vs 6 Pro vs 6X Pro – What’s the Difference?

If you find this post helpful, please share it.

Just like the Fenix 5 series, the Garmin Fenix 6 series is made up of three main members; the smaller Fenix 6s, the medium-sized Fenix 6, and the bulkier Fenix 6X. Each of these comes in four different models except for the Fenix 6X which is available in three models. You get a base model which lacks music storage and maps, a Pro edition that allows for onboard music storage, and premium sapphire and solar editions. Every member of the Fenix 6 series is rugged and durably built. Each of the units is also loaded with lots of activity tracking features plus equipped with long battery life. In this post, we’re comparing the differences between Garmin Fenix 6S Pro vs 6 Pro vs 6X Pro to help you make a more informed decision.

There are 11 members in the Fenix 6 series as listed below. The differences between the respective models come in the ability to preload music and load maps. Meanwhile, the Sapphire edition has a premium sapphire screen and Diamond-like Carbon (DLC) coated bezel. The Solar edition has a power glass that supports solar charging plus a titanium bezel.

In other words, the Standard editions of all three sizes are the cheapest because they lack music storage and the ability to load maps. The Pro, Sapphire, and Solar editions allow for music storage and maps, and as a result, they are priced higher with the Solar edition having the longest battery life and also the most expensive.

  1. Garmin Fenix 6s, 6s Pro, 6s Pro Sapphire and 6s Pro Solar.
  2. Garmin Fenix 6, 6 Pro, 6 Pro Sapphire and 6 Pro Solar.
  3. Garmin Fenix 6x Pro, 6x Pro Sapphire and 6x Pro Solar.

What’s the Difference?

Garmin Fenix 6S Pro vs 6 Pro vs 6X Pro
The Fenix 6s unit is the most compact, but has the shortest battery life.
  1. The 42mm Fenix 6S Pro with the smallest case size is the most compact, it also weighs the least and is slimmer than the other two which makes it the most comfortable wear out of these three. This makes the 6S Pro the best choice for women and those with smaller wrist sizes.
  2. The Fenix 6X Pro with a 1.4-inch display has a slightly bigger display size than the other two which allows you to see more at a glance.
  3. As a result of its bigger size, the Fenix 6X Pro has the longest battery life that allows you to go longer from a single charge.

In other words, all three smartwatches are outstanding in design, features, and long battery life. However, going by the varying sizes, your preferred choice would basically depend on your wrist size.

And if you want longer battery life, the Fenix 6X units offer the longest battery life.
