This premium leather watch band is carefully handcrafted from full-grain calfskin and hand-sewn with waxed thread. These straps are great straps to watch "come alive" with use and complement the look of the Apple Watch series. Over time, a Roarcraft leather watch strap will darken in color and deepen in tone achieving a rich and unique patina that is as individual as you are. Apple Watch Series Ultra, 8, 7, SE, 6, 5, 4, 3 Apple Watch is not included. If you prefer silver buckle & spring bar adapter, please reach out to customer services.
