This is our most popular watch strap! These are made to order from ultra rare Swiss ammo pouches that dates back to the 1900s. Most were made around the 1940s to 1970s. They range in many shades of brown from a very light orangish tinted brown to a very sophisticated dark brown. The thickness is around 3mm to 4mm and they will last a lifetime, even through the toughest of conditions. We keep the construction very simple with 1 piece of vintage leather and your buckle of choice, along with tubes. Handmade In The USA (San Diego, Ca) Turnaround Time: Generally 3-6 Business Days
