How about a custom-made perfume bottle with personalized engraving? You could have his name or your anniversary date engraved onto the bottle to make it a special and unique gift. Additionally, you could also give him some high-quality fragrance to fill the bottle with or purchase a limited edition or vintage perfume in a beautiful bottle that he can add to his collection. Another option could be to gift him a book or coffee table book about the history and art of perfume bottles.
Or you can get him a star map with the date of your anniversary.
