If the money is not an issue, my advice is to try to time it as a significant "reward" to yourself, for a significant "achievement" either academically, socially, or anything that has a lot of personal meaning to you.
That's exactly why I don't feel bad about buying my first Breitling. I've worked for 2 years in a hellhole and am going to reward myself, the way I see it is that I've earned it over the past two years, so no guilt

I've also been able to save a bunch of money so I have a little to play with. As far as being too young, I think it would be fine, I got a TAG for HS graduation and I never felt weird for owning an expensive watch, until it got stolen. Good luck with your purchase, make sure you post pics after you get it.
