The Classic Buckle for the 38mm and 42mm Apple Watch is made of Dutch leather from the ECCO tannery in the Netherlands, and is a refreshingly new take on tradition.
I didn't order the Classic Buckle for Apple Watch the same time as I ordered the Watch itself and the Leather Loop. I ordered it later, when I was at the try-ons, and I was speaking to one of the Apple reps about it. I'd almost dismissed it before then. The Link Bracelet was going to be my classic strap, after all, and the loop, my leather. But we got to talking, then trying, and then liking... From there it was one tiny step to ordering.
