Building frankens has often (for me at least) more to do with the pursue of perfection while learning a new skill. You can open up and destroy a $300 rep but you're not going to do it when you've payed $6000 for a watch (perhaps because its perfect, but that's one of the reasons I don't buy gens anymore).

I've only built a couple of franken watches, I've built a Omega Planet Ocean for a friend and my Super Avenger, on my SA I'm into it almost the same amount of money as a used gen, however there are 2 crucial differences, one is I spent it in parcels and didn't have to tell the better half I was spending $2k on a watch when I have over 30 of them, and secondly I had the pleasure of putting it together for the most part and learning new things in the process. Win Win situation for me and although I don't have the papers (I do have the gen box), I can say that I've built the watch I'm wearing and that gives me much more pleasure then anything else.

To be called out, well 99.9% of the people don't even know what a Breitling is and the other .1% lives here so doesn't cross my mind. If I do, it doesn't bother me the slightest.
