Seila Leather LLC is a family of watch enthusiasts dedicated to exceptional craftsmanship. Founded in Seattle and now based in Japan, we handcraft every watch strap in small batches using premium materials sourced from around the world — including Horween, Italian vegetable‑tanned leather, Shell Cordovan, and other specialty hides.

Each strap is made entirely by hand, one at a time, ensuring durability, comfort, and a precise fit. We believe in quality over quantity, which is why our work is produced in limited numbers and given the attention it deserves.

From classic leather designs to custom handmade replacement straps for Seiko, Rolex, and other timepieces, our goal is to create pieces that elevate your watch and last for years. It’s our honor to share our passion for fine leathercraft with watch enthusiasts around the world.
