Roldorf's The Boundary

// Inspired by Boundary Bay // 49°00′N 122°55′W //

For the Boundary, we use the best genuine cowhide leather. The surface appearance of the band comes in a linen structure, which is created by a patented coating of the upper leather and makes the band almost waterproof. The embossing gives the strap and watch a sporty touch and a special character. The water-resistant effect is reinforced by an additional waterproof leather insert and an equally waterproof lining leather. The strap fits perfectly with IWC’s sporty watches but also with any other watch. Like all our straps, this strap is exclusively handmade in the Bavarian Forest.
