If you’ve ever spent time researching quality boots or dress shoes, you’ve no doubt heard of Shell Cordovan leather—and you know why its remarkable durability makes for an excellent watch strap. Considered the absolute cream of the crop in the world of leathers, Craft + Tailored source theirs from Japan’s Shinki Hikaku tannery, which produces a version of this leather that is especially uniform in its color and texture. It looks great, it doesn't stretch out from pulling and tugging the way many less expensive leather straps do, and it may be the last watch strap you ever buy.
