My Nautilus also arrived yesterday and let me add my "Wow!" to the chorus of wow reactions to this light. In the instruction sheet that's packed with the light, Enrique mentions that he as been working on the Nautilus design since April and wanted to get every part of it as close to perfect as possible. Well, Enrique, all I can say is "Mission Accomplished!"
The craftsmanship is incredible and every bit as perfect as the pictures reveal. I've found that limited edition custom lights, as expensive as they can be, often have a tendency towards being hit and miss when it comes to "fit n' finish" quality. You know what I mean: the LED's not quite centered, the knurling could be better, the HA is mismatched, the body has some machine marks, the battery rattles, etc. NOT SO with the Nautilus, which has the no excuses fit and finish of a Patek Philippe watch. Perfectionists take note: this is the flashlight for you.
In terms of performance... wow again. If you want to know how far LED technology has come in the last year or so, just turn the Nautilus to BRIGHT! and then consider the runtime you're getting out of a single CR123 battery. Unbelievable. Hands down, it's also the best Cree beam that I've ever seen.
The ergonomics are great, too. It's small, but not too small, and the brass innards give it just the right amount of heft. When you pick up the Nautilus, it just feels like a tool of superbly high quality. And looks? Can I just say wow one more time? The Ti body with brass accents oozes a highly refined sense of class, while also being capable of handling daily abuse.
I would imagine that Enrique will probably have a few Nautili left for sale due to some orders falling through, and I'd strongly suggest snapping one up if you missed out when the order list closed.
