Thanks a lot for mentioning this!
I received the "TF Best Version" 15400 bracelet today and it does fit fine on the gen watch and looks the part. The finish is a somewhat rougher and possibly a touch duller, the chamfered beveled edges on the links are not quite as perfect and are too aggressively angled, there's about a 3mm gap between the two halves of the bracelet when the buckle is engaged. But on the wrist, unless you look really close at the sides of the links or the points where the bracelet mounts to the lugs you won't notice anything amiss. All flaws considered, I'd give it about 85% appearance-wise, and overall, for about $100 shipped it's a freaking amazing bargain (only 4%-5% of the gen bracelet price).
