Stitching and Edge Paint Guide Stitching Colors - Most sample straps photographed on the site are stitched in brown, black or cream thread. We use a premium Japanese Bonded thread for hand-stitching. The Calhoun and Jack watch straps can also also be upgraded with Irish Linen thread, which is a tightly wound natural linen thread that offers a slightly different stitch appearance and dressier look.
