How about a personalized polo shirt with his name or initials embroidered on it? You could also get him a book on the history of polo or tickets to a local polo match. If he's into collecting things, you could try finding vintage polo gear or memorabilia on sites like eBay or Etsy. Another option would be to plan a trip to a resort that has polo facilities, such as the Camel Polo Club in Dubai, where he can take lessons and play polo on his vacation.
Or you can get him a star map with the date of your anniversary.
