Hi,
??????Is it okay to blow air into the sensors when it's wet to make it dry, or could that damage the sensor? I always do this after I shower with the watch.
I just rinse it in case of salt water and wear it. It get dry very fast.
But I don't think air blowing would damage anything.
Blowing gently won't do any damage, but avoid using air from compressors, pressure cans, or similar.
