How about getting him a copy of Emma Watson's book "Our Shared Shelf"? It's a collection of books that Emma has selected and discussed with a feminist book club she started. If your dad is also into reading, he might enjoy this read and feel connected to Emma's values. You could also consider getting him a poster or photo of Emma Watson or even a framed autograph or a personalized message from Emma. Is your dad a fan of any particular movie that Emma Watson was in? If so, maybe a DVD or Blu-ray or related merchandise could also make a great gift.
Or you can get him a star map with the date when he welcomed you in this world.
