You can order the sapphire and install it yourself (or have it installed). Or, you add one of these to your SKX013-order, where you selected the “install ordered sapphire”-option (adds € 27,50 to the order, for installation)
There are two available shapes:
Flat with a large facet, like the original hardlex.
Double domed, so no distorted view. It also has a facet, needed for the bezel insert.
