Chocolate Brown Classic Horween Leather Watch Band - Seiko Alpinist SARB017 / SPB121 (20mm)

Skillfully crafted to evoke the nostalgia of 1960s & 1970s, our Horween Classic Collection pairs perfectly with dress watches, chronographs, smartwatches, and divers alike. The distinguishing ribs provide a vintage look and feel to your wrist and watch. This version features Dublin Horween® leather, 316L stainless steel hardware, and a soft top-grain Nubuck lining.

Our Chocolate Brown Classic Quick Release watch straps feature leather from one of the oldest tanneries in the US. Horween Leather Company is based in Chicago, which has been tanning and producing high-quality leather for over 100 years. Dublin Horween is a vegetable-tanned leather and has been hand-glazed with a waxy feel. This premium treatment allows the natural characteristics of the leather to shine through. Be aware that a natural patina will develop over time, giving this watch band a worn-in, timeless feel. These simple imperfections will add a rich texture to any timepiece.
