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.

Constructed from hard-wearing, full grain Italian calfskin leather, the Heavy Calf is scratch resistant as well as water resistant to 100m. Hirsch’s proprietary Coup Franc treatment (a rembordd edge with three layers of hand-applied lacquer) provides enhanced durability. Hirsch’s Oysterglove Supersoft 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.
