You should contact Suunto. Not so much to complain, but let them know as they are always looking for product feedback where you can detail the conditions that lead to the bubble.

A hiker friend of mine had a bubble form in her compass and after contacting Suunto, they sent her a replacement compass that was a couple of steps up from her model. Suunto also provided a return courier packing slip so she could send in her original compass.
