Product Description: Taking it up a notch with the Limited Edition model of the Series 8 Collection. The 831 model has the same eye-catching octagonal case as the 830 model, but with a simpler monotone dial. The stylish hands taper off toward the outer edge of the dial, and the detailed index markers provide a dynamic look. The bold hairline finish of the strap with its clean, straight lines, combines beautifully with the simple design of the case.
