I'm 21. My father got me in to watches. He got me a cheap Quartz citizen at a young age, then an auto orient, a Bernhardt and an accutron VX200. Now I've got the bug almost as bad as he does although his collection is much better. Maybe you could buy him a cool watch? It doesn't always work (I've done it with my friends... And then cry inside when I see naked wrist) but it's worth a shot. The WIS syndrome IS contagious although sometimes you have to try hard to infect. Just my $0.02 as a son.
He sent me this picture yesterday of his wrist. We basically have our own WRUW texts 馃槈
BTW if I was your son you would get lots of compliments and stares. THAT is a BEAUTY. I really really love it!!!
Edit: like father like son. My 2254, being 9 hours away from my Dad it's cool to be wearing the same watch. Can't explain it.
