Why does my watch sometimes have a strange vibration and noise when my Breitling Watch is on my wrist?
This is most likely because you have a Breitling with the Valjoux 7750 base movement such as the Breitling Caliber 13. Unidirectional winding movements like the Caliber 13 sometimes get a burst of centrifugal force from movement you made with your hand, causing the rotor to spin several times. That vibration you feel is likely the rotor spinning. It also may be that something is falling apart inside your watch. The above is not meant to diagnose possible watch failure, just a common occurance and question asked.
