Paul Smith Retrograde Iron Mask Dial: Blue Quartz / Battery Operated Accessories: None Size: Width: Approximately 48mm Wrist Size: Approximately 17cm (Measurements are approximate. I don't have the extra links for adjustment, so it's being sold at its current size.) There are some scratches from use. The battery was recently replaced to confirm operation. Overhauling it in the future will allow for longer use. Dial Color: Blue Belt Color: Silver 0924
