A small French tannery established in 1803 produces the supple Granada leather for this elegant band. The smooth top-grain leather is lightly milled and tumbled to maintain its refined texture. What looks like a solid buckle is actually a two-piece magnetic closure that’s delightfully simple to secure. We also added an inner layer of Vectran weave for strength and stretch resistance. It’s the same material NASA used to make the landing airbags for the Mars rover spacecraft.
