Garmin released eight new fenix watches in their fenix 7 series, and it might be confusing as to which one you want to purchase. Here is a quick and easy breakdown of the differences between models and how to figure out which one is best for you.
Step 1 - Watch Size
There are three different size displays and watch bands that you can choose from depending on your preferences. The fenix 7s is the smallest, fenix 7 in the middle and fenix 7X is the largest.
108–182 mm (4.25-7.16”)
125–208 mm (4.96-8.18”)
127–210 mm (5-8.26”)
Step 2 - Lens Type/Additional Features
Type of Lens
Corning Gorilla Glass DX is designed to be scratch-resistant, but it is not as durable as the Power Sapphire lens.
The Power Glass lens also uses Corning Gorilla Glass DX , but adds the ability to convert sunlight into battery power.
Sapphire Solar model
The Power Sapphire lens has the ability to convert sunlight into battery power and is also incredibly durable. It is the third hardest mineral, right behind diamond. As a result, the lens is much harder to scratch than glass.
