Link bracelet: "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. In part thats because they arent simply a uniform size, but subtly increase in width as they approach the case. Once assembled, the links are brushed by hand to ensure that the texture follows the contours of the design. The custom 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. Available in stainless steel and space black stainless steel." Milanese loop: "Based on a design developed in Milan at the end of the 19th century, the flexible metal mesh of the Milanese Loop wraps fluidly around your wrist for a perfect fit. Achieving the desired look required magnetic stainless steel. But off-the-shelf materials didnt offer the necessary purity or corrosion resistance. So we created our own alloy and use a new thermal treatment that makes it more durable. The mesh is woven on specialized Italian machines, and every end piece is individually laser-welded to ensure smooth edges."
