Meanwhile I had time to disassemble the watch. There were no signs of wear or missalignment. Pressing the actual button directly did not work for BTN2 (whereas it works for BTN1 and BTN3).
The dis- and reassembly worked well with the instructions of the video.
Before disassembly after picking up the watch, I'd gotten one BTN2 click where the watch responded. I could not replicate this. Conclusion: There is a hardware problem.
@Gordon thanks for the wonderful support! As I am in for the Banglejs 2 crowdfunding, my intention is to donate the broken Banglejs 1. I'll reply to your email about how to do this.
