How about getting him a classic or unique perfume bottle that's hard to find? You could check out antique stores or online marketplaces for vintage and one-of-a-kind designs. Another idea is to get him a personalized perfume bottle, which can be engraved with his name or a special message. Another option is to find a special fragrance he may not have in his collection yet, and pick a bottle that he would appreciate.
Or you can get him a star map with an important date you share.
