hanks for your report. We've found that this issue is often caused by a substance around the button. To try and loosen or remove possible debris, please submerge the Pebble watch under warm water for a few moments. Then remove the watch from the water and firmly press and hold each button (individually) for 7 seconds.
If this does not help, could you please upload a short video illustrating the problem to a video-sharing site (e.g. Dropbox, Vimeo, Youtube, Google Drive, etc.) and provide us with the link
