A classic design pioneered by WWII aviators who liked the way the pad protected their wrists from a metal watch. Our version is constructed in genuine shell cordovan leather from one of America's oldest and most renowned tanneries, Horween. Its signature cordovan is made from a specific part of horsehide that, according to the old-world tanning technique, is soaked in vegetable liquors for six months (the process ensures firm leather with an even tone). Each piece is then hand glazed by highly skilled artisans. The meticulously crafted strap comes in two distinctive shades: natural, a classic cordovan hue, and number four, a medium shade that's increasingly difficult to find (the lighter the color, the harder it is to conceal imperfections in the leather).
