20mm Blue leather with embossed faux crocodile pattern military style NATO watch strap. Plain steel hardware. I bought these years ago and now selling the few remaining. They are stamped I.W.Suisse and Genuine Leather.  Colours available are blue, dark brown, green and red. I have a few duplicates if you want more than one, but not many. All straps are 20mm width and 1.2mm thick. Photo is Orlando Bloom wearing the dark brown version to match his tropical dial Milgauss Ref.6543.
