Hirsch Grand Duke black XL 20mm — long alligator-embossed calf strap

Hirsch Grand Duke XL 20 mm watch strap for a broad wrist

The Hirsch Grand Duke 20 mm in black leather stands out — the XL version of the Grand Duke black meets a specific need: broad wrists, where a standard strap runs short on length. The leather, the waterproof alligator embossing and the red stitching are identical to the standard model; only the length changes, and no extension is used.

Sport and water resistance

A more generous, sporty take on the Duke, the Grand Duke is waterproof and shrugs off water and perspiration. On a large wrist, the pronounced doming keeps all its presence.
