Hirsch OSIRIS Black Quick-Release Calf Leather Watch Strap

£28.95 - £77.45
Free shipping on all orders over £100.00.


This Hirsch strap features an integrated quick-release spring-bar, allowing you to quickly and easily swap it out without the need for additional tools. Click here if you'd prefer this strap equipped with a pair of standard spring bars instead.


A wonderfully smooth and refined strap, the Osiris has a timeless elegance that is well-suited to both women's and men's watches. The strap has minimal padding for a low-profile look that is understated, yet impressively dignified.
