I accually just got this one from Andrew;
FM Casablanca Chronograph SS Black - Lemania Movement
The Fit and finish on the watch is great.
The hands and numbers are very accurate from what I can see. The case is pretty much spot on, the engraving on the back is nice and smooth and looks very GEN. I'm not sure about the AR coating. The Band however, Just Screams Rep. It's a good leather strap, but really, when you look at the watch, this is the thing that jumps out at you. It has that $400 rims on a ferrari look, if that makes since. I'm going to be putting a nice black croc strap on mine from Banda.com. The model I picked up has the Lemania hand wind movement. I set it on Thursday and so far, it's kept great time.
Andrew was great during the whole ordering process and kept me abreast of the shipping and tracking of the watch. I'll most def be ordering from him again. Probably this week.
I know this isn't the exact model you're looking at, but it's the only FM rep I have experiance with from the same vendor. Hope it helped.
