Crafted from the same 316L stainless steel alloy as the case, the Link Bracelet has more than 100 components. The machining process is so precise, it takes nearly nine hours to cut the links for a single band. The custom-made butterfly closure folds neatly within the bracelet. And several links feature a simple release button, so you can add and remove links without any special tools. An additional diamond-like carbon (DLC) layer gives the space black stainless steel its distinctive finish.
