All our bands 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 watch straps 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 316L 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. With every watch band purchase, we will also supply pair of premium quality stainless steel spring bars set and watch band replacement tool.
