Vibration damaged?

Hi all,

I always set my alarm clock in the morning on my G1 which works perfectly. But now since a couple of days I have noticed that the vibration function on the watch is significantly louder than it used to be. 

I have been searching for a way to change the level of vibration, thinking maybe it increased for some reason. But I am afraid something inside the computer became loose and is now rattling around causing the noise. 

Anyone got some experience with this issue or a solution?
