Not shown here: lots of heat and careful prying. Like the Apple Watch, the Fitbit Sense's ingress protection means the very thin gap between the display and the housing of the watch is lined with adhesive.

Even with a heat gun and extremely thin prying tools it is difficult to get the display to budge. A semi-unprotected OLED display underneath the glass and booby trap cables and near the edge where prying happens add to the challenge.

Underneath we’re greeted by a small bracket fastened with tiny T2 Torx screws covering the connectors we're aiming to disconnect—no problem for our Pro Tech Toolkit.
