Hirsch Grand Duke black 18mm — men's alligator calf strap

Grand Duke 18 mm watch strap, more generous than the Duke

The black leather Grand Duke 18 mm strap is the more generous, sporty take on the Duke — a model in its own right. Its alligator-embossed calf, with pronounced doming and red stitching, gives it an assertive presence in 18 mm. It blends elegance and character where the Duke keeps to strict restraint.

A waterproof leather

The Grand Duke is waterproof: it shrugs off water and perspiration, which makes it versatile for everyday and active wear. The semi-matte alligator embossing catches the light with restraint, and the red stitching adds a sporty accent.

Tool-free change

The pronounced doming and careful finish keep it comfortable. The tool-free Hirsch Quick Release spring-bar system lets you fit it without a watchmaker.
