A gift for someone who is 1 year sober?

Someone very close to me is going to reach one year of sobriety soon, and I want to get him something, or show how proud I am of him. I want to be able to show him that I think he is an incredible person as well. Any gift ideas? He’s in his 20’s, and he’s very stylish with clothes in a good way (he doesn’t just follow trends). I thought about getting him some sort of necklace with a meaningful pendant or something. Any ideas are appreciated!
