Hmm, back before I was married and had a house payment etc etc I was able to buy and then sell a few high end watches...

Anyway, if you like that watch go for it, enough said. But, tritium will die out. I think if you are going to drop some dough on a watch it should be able to be passed down to your childern and your childrens childern etc. I just don't see that happening with a tritium watch. That is why I sold my Marathon and it ran like a top.

If I am ever blessed enough financially I would love to one day pick up a Rolex or something. The Rolex movement is super tough btw.

Your brother has done something cool, how fun will it be to 25 years from now look down at your wrist and see something that has been with you that long.

I don't own any knife that will ever last 25 years...but knives do wear, if you use them, a good watch is a lifetime investment.
