I'm very, very happy with it. It's flawless, and the strap is surprisingly great, too. I've used an emery board to take a couple of sharpish edges off the titanium case (damn, titanium's hard!) and I've been wearing it a lot recently. Can't praise getatwatch enough, he's built me a custom at the same price as off the peg. Definitely worth the extra for the superlume, and suggest going for his "handcut" leather straps as they're particularly thick and luxorious!
I've had it on one wrist and a gen white-face Luminor on the other wrist courtesy of a mate and I have to say - I kind of prefer mine....!
I'm sure you'll love yours.
Re the date thing - you mean on my SMP? Yes, saw that and all appears well now I've stuck to that. Still not sure if you can actually *damage* anything if you don't do this but having not wanted to risk it, I've just been changing date outside of that window and it's worked fine for me so far, ta.
