I recommend a flexible slightly thick double sided tape. This model was designed with 1.9mm thick double sided tape (with foam core) in mind. May or may not work with 3M VHB (I can't find my roll of it… need to go buy some more)
If your screen is cracked like mine, I recommend running over it with some clear cellophane tape, preferably a good quality tape so it holds up until you can get your device fixed.
Best to leave it clamped or buried under something heavy until the tape has time to properly bond to the device.
The author remixed this model.
Made the ring that goes around the watch body 2mm longer so it works better with double sided tape that is 1.9mm thick.
