It happens quite a bit to me, I think because of the shape of my skinny wrist. I have that prominent bone as well and I wear my watches like you.
I have found that shifting links around so that the clasp rests in a different place helps, usually the clasp being nearer the 6 if that makes sense.
In extreme on cheaper watches I have sometimes just switched the bracelet round so that the clasp shuts the opposite way.
Both methods seem to work for me, but it is an irritation.
