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.
Hirsch's popular Osiris Box strap is made from finely-pored, flexible full grain cowhide box leather with a silky shine. With its slim, flat profile, it's a great choice for both men and women. 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.

The Osiris is more supple than Hirsch's Forest out of the box, and feels slightly thinner, giving it a classic feel. The outside leather is also feels more "slick" and has a slight shine to it, increasing the classic-ness of the strap. Feels soft and comfortable on the wrist, would definitely buy again for a dress watch.
Good quality and beautiful dark color. Exactly what I was looking for. A little thin, but wears comfortably and I am guessing it will also age nicely over time.
