They have been making the best all-around multisport and outdoor smartwatches in the industry. Garmin watches are packed with state of the art features, and they are continually pushing the technological limits.

With the latest model, Garmin Fenix 6, we’ve seen many different options to choose from, and finding the right one for you can be confusing. Let’s jump into details and find out the differences between each Fenix 6 model.

Overview of Sizes

Garmin Fenix

The most significant difference that is easily noticeable for the naked eye is each Fenix model’s physical size. As they did with the previous Fenix 5 version, the Fenix 6, 6s, and 6x come with different screens and bezel sizes.

Garmin Fenix 6s is the smallest of the bunch with a 42mm diameter.

Garmin Fenix 6 is the standard size with a 47mm diameter.

Overview of Type

Overview of Type

It is essential to understand that each size comes in different models. Most smartwatch manufacturers offer other models by making the smartwatches from different materials or offering premium features.

If you choose the Garmin Fenix 6, you’ll have five different models to choose from:


This is the less advanced version of the Garmin Fenix 6, and it comes with all the basic functions, and is not equipped with features like WiFi, built-in maps, Garmin Pay, Garmin Music, and more advanced features. The silver model is the budget version of the Garmin Fenix 6.


We’ve seen Pro models of Garmin watches in the past, and they are the standard edition of the watch but packed with all the advanced features. There is no difference in the build materials, so it has the same Corning Gorilla Glass and stainless steel bezel.


If the Pro version is not enough for you, the Sapphire model is a nice way to advance to a higher built standard. This model has the same features as the Pro, but instead of regular Corning Gorilla Glass, it has an unscratchable sapphire glass like most premium watches.

Sapphire Titanium

If you think the Sapphire version is the most premium model you can get, you are wrong. As the name suggests, the Sapphire Titanium model has the same features as the Sapphire model, but the crown is made from titanium, which is incredibly tough but lighter than stainless steel.

Pro Solar

This model has the same functions as the Pro and Sapphire models but comes with an incredible feature. It is equipped with Solar Power Glass that can pump juice into the battery when exposed to the sun. This can extend the battery life of the watch.

New Interface

Garmin focused on improving the user interface in order to make data more visible even when you are doing any kind of physical activity. Since the watch doesn’t come with touch-sensitive controls, sometimes it can be hard to switch over to menus and browse data while running, for example.

The newly updated user-interface on the Garmin Fenix 6 is more structured and refined. If you already have a Garmin watch, don’t worry, you will quickly get comfortable with the new layout.

The most significant difference in terms of user-interface is in the Widgets, where you can get a lot more information simultaneously. With the previous version, your only option was to scroll to widgets and browse your data, whereas now you can combine multiple widgets simultaneously.

You can add up to 8 data fields at the same time, which makes the smartwatch very easy to use.

Pre-Loaded Maps

If you decide to go with the Garmin 6 Pro or Sapphire option, you’ll be excited to hear that they improved the pre-installed maps. These topographical Europe maps will guide you to your final destination with incredible accuracy.

This new feature works flawlessly, and it can find the optimal route no matter if you are running or cycling. You can also choose different map colors and layouts from outdoor to dark or high contrast, which work great in any environment.
