Part of our limited August release. The Sierra in Natural Buttero is hand-stitched and fully finished with a Zermatt liner, natural edges, and two floating keepers. This leather comes from Conceria Walpier, a tannery in Tuscany, Italy known for traditional vegetable tanning. It starts out a light natural tan and darkens with wear, picking up color and character over time until no two straps look alike. Finished with your choice of buckle.

Leather Care

Real leather is meant to age and tell a story. Over time your strap will develop patina, subtle markings, and a finish unique to you. While durable, no leather is designed for regular water exposure. If your strap gets wet, allow it to air dry at room temperature. A light leather balm or conditioner may be applied occasionally, though it can slightly deepen the color.

Built From the Best.

A watch strap gets more contact with your skin than almost anything you own. It should be made like it matters. We hand-select leather from tanneries trusted by the world's finest luxury houses — Horween in Chicago, and heritage tanneries across Italy and France. Then we cut, stitch, and finish each strap by hand in our Utah workshop. The stitching, the edges, the feel. Every detail is deliberate, because the watch on your wrist deserves nothing less.

The Sierra strap in Natural Buttero Leather is absolutely stunning. Thank you Threaded Leather folks for making a robust, substantial leather strap of exceptional quality and finishing. I never want to take it off, it is so comfortable. Anyone looking for an artisanal level leather strap for a nice timepiece- Threaded Leather is punching way beyond their price. Everything about the strap and experience has been fantastic!! Also best American made leather strap I have seen.
