Headquartered in Klagenfurt, Austria, Hirsch was established in 1765 as a leather workshop and tannery. It remains a family-owned business to this day, and continues to gain recognition for excellence and innovation in watch strap design. Looking for the finest quality full grain alligator grain-embossed Italian calfskin leather? You'll find it in Hirsch's Duke strap. With matching stitching, a semi-matte finish and medium padding, the Duke is a total classic. Hirsch's Softglove lining leather is hypoallergenic and gentle on the skin. All of our Hirsch straps are integrated with handy quick-release spring bars. Prefer standard spring bars? Quick-release bars are easy to remove: simply slide the lever as far as you can to the left, then gently bend back the strap corner until the bar emerges from the slot.
