What should I get for my uncle who is turning 50?

My uncle is turning 50 in a week and I still haven’t gotten him anything. He is the man who has everything already so to speak. I’m getting him a card and writing in it but other than that I have no clue what to get him. He has enough money to buy whatever he needs, and he doesn’t really “need” much either. He already has golf clubs, ties, sunglasses, clothing, tech stuff, so I really am confused what to get for his 50th b-day.
