Hey all, First thread started by me. I recently bought Classic Buckle Saddle Brown, which is pretty nice even for $150 IMO. Beautiful. Smooth soft calf leather. So, i decided to look up what kind of leather it is...we know that it is from ECCO. Here is Apple's website description: http://www.apple.com/shop/product/MLHH2/42mm-black-classic-buckle "This traditional design has been updated with a new calf leather that ages naturally over time to acquire a beautiful patina. The contrasting interior lining creates a dramatic two-tone look, and the filleted edge detail provides a clean geometry. Available in black and saddle brown." Sounds good. But i wanted more info. Googling "Ecco leather apple watch" brought me this site: http://eccoleather.com/en/apple-watch Notice the link address. Eccoleather website with apple watch in it. So, it seems that Apple Watch Classic Buckle 2nd gen leather maybe using Ultrathin leather technology from ECCO. Quote: PREMIUM LEATHER TO INTEGRATE WITH MODERN DESIGN Ultrathin® leather technology The development team in our Open Circle Lab spent over two years perfecting our new Ultrathin® tanning technology. Their aim was to redefine the conventional limits of the "thin split" in the world of premium leather. The result was the creation of an advanced MicroSplit process and launching of our new Ultrathin® range. Now visionary product designers in the technology and electronics segment can integrate the timeless character of genuine premium leather within cutting-edge hi-tech industrial design. Forming this bridge between leather's past and its future is precisely the role ECCO Leather hopes to serve in the world of contemporary product design. So, what is splitting process in leather?

The bottom is used for suede or split leather for other uses.
