Black Shell Cordovan Strap
NATO style straps are utilitarian and their origin can be nicely traced back to the seventies where they were conceived by the British Ministry of Defense. The NATO strap, or the G10 strap as they were commonly referred to at the time, should ensure your wristwatch stays on your wrist under a variety of circumstances. Where a normal watch strap's life ends, the NATO's just gets started. With this in mind, Shell Cordovan NATO straps are about as tough as they come.
The leather is the standard shell thickness of approximately 1.6mm, which is a bit thicker than a nylon NATO.
The huge difference with our normal leather is that Shell needs some breaking in at first, like with a good pair of shoes. After the breaking in period it gets incredibly supple and the surface takes on a life of its own. After that, treat it well and these will last a very long time.
