All our watch straps including back lining is made of genuine full grain leather. Our bands are of the highest quality which means we do not use split or bonded leather. This ensures that our bands do not crack after continuous wear. All of our bands have their keepers (moveable loops) both glued and stitched to reinforce their strength. We use only the best quality of stainless steel buckles. Unlike brass buckles, which often turn green after wear, our quality stainless steel buckles are hypoallergenic, and keep their colour even after long-term wear. All of our leather bands are warrantied for 1 year against any manufacturing defects.
