yep, delays are due to the fact that TTK Nautilus have been seized (like 11 at the same time) and that TTK can not afford replacing all of the immediatly (hell, that an awfull lot of money, those are'nt cheap). He'll deliver, no doubt, but he replacing the one by one and it takes time.
The tradeoff with TTK is quite simple: you've got the best garantee you can dream off (wether you're talking of illegal good or not, his garantee is nearly the same as if you were buying a Seiko at an AD), he test all the watche for accuracy (near COSC), waterproofing and perfection, BUT there's a delay for this.
The TTK Nautilus delay is also due to bad luck with custom, but let's face it, how many dealers would have replaced a $5K loss? Even with a regular - legal - eCommerce buying, the delay could be as long.
I bought one of my first rep with TTK, and it took 10 days to arrived from Thailand to France, top noch.
