The sapphire solar models of the Fenix 7 are quite widespread and a bit confusing at first glance. All are power glass and feature solar expedition GPS, but the sapphire models all share the ability to protect the bezel to a wider extent than what is seen on the standard Fenix 7 model. The solar sapphire editions feature a power sapphire lens with sapphire crystal solar charging being the key differences on the most expensive solar sapphire models. The solar sapphire watches also have titanium bezels across these new watches, which even further protects the longevity of these multisport watches.
