This watch strap is made completely by hand in our San Diego, Ca workshop from some of the finest leather, genuine Horween Chromexcel leather. Chromexcel has 89 separate processes and takes 28 days to complete. That all happens before we receive the hide and handcraft your unique strap. It will last for a lifetime and gain a lovely patina with wear. Horween is known as one of the best tanneries, in not only the United States, but throughout the world. Horween has been producing top quality leather since 1905 and we are proud to utilize their leather in many of our high end products. Beyond this, we use ultra rugged stainless steel hardware that will stand up to whatever is thrown at it and a 4 ply waxed linen thread which gives our straps their durability and stunning good looks. This leather is the best of the best and will last a lifetime with proper care.
