Difficult SO ...

I am married to a man that is very hard to shop for. His birthday is almost here and I desperately need help with ideas of what to get him? 
It's getting more and more frustrating every year... He always says "I don't need anything" or want anything which only makes it that much harder. 
I usually buy him clothes, Cologne, watch... Those are getting old. What do you get your SO? My man doesn't have any hobbies and is not into anything. TIA!
