This is a 13mm black leather band with 13-12 i.e. 13mm to watch lug and 12mm to buckle. The length is 120mm and 75mm. Standard length for watch band. Ostrich skin style pattern. Including stainless steel buckle. The band is actually 14mm but able to fit to 13mm watch lug cause the leather at the side of watch lug is soft. This will give perfect fit for long time during the wear and tear.
