We're serving up lots of details in this section because size and build quality can be a major factor in your GPS fitness watch purchase. A runner may want a slimmer, lighter watch, whereas a bulkier Garmin watch may be more resistant to the elements and have more room for features. A smaller display may be perfect for some workouts, while a larger screen may offer more stat data at a glance. It all comes down to you!

Garmin fēnix 6/6S/6X Pro & Sapphire
The fēnix 6/6S Pro & Sapphire have the same dimensions and display sizes as the standard fēnix 6/6S.
