Hey look, a batch of T4 Torx screws on the front! You had us worried for a second there, GoPro.

Manufacturers' first attempts at waterproofing usually result in completely glued devices, oftentimes without a non-destructive means of entry. Looks like things are going to be different here.

Screws out, and the lens cover comes free, revealing access to... an o-ring.

The glass lens cover is probably the most likely part to break on the Session, but it's also the easiest to replace. It's good to see that GoPro had repairability in mind for the lens cover, as they sell a complete lens cover replacement kit.
