If you don't mind me asking, how often did you wear that DJ? Was it a daily? Or did you save it for special occasions? I always wonder how much I should wear a watch that is supposed to be for someone else.
With your son, did you try to engender an appreciation for this hobby? It may just take a little time for him to appreciate watches. And certainly, I think he will appreciate it as you get older and as he wants a part of your life in his. Having children of your own tends to give that perspective!
