This is a watch that I've also desired for quite some time - but I have seen a couple scenarios where the DLC would flake off... Nothing major, but if you look around online you'll find some photos of it. I'm sure you could always get it re-coated if it happened to you, but I feel for this much money - having to worry about re-coating a watch is a bit of a deal breaker.
I took another look at this – admittedly – unique model. Yes, it's special, but the watch still doesn't appeal to me enough to change my initial opinion. I am very curious how you will decide.
