Hirsch Heavy Calf gold-brown 20mm — waterproof leather watch strap

Gold-brown 20mm waterproof leather watch strap

The 20mm Heavy Calf leather watch strap in gold-brown is a fully impermeable leather, certified 100 m water-resistant. Gold-brown warms a steel watch and takes waterproof leather out of the purely sporting register. It is the model that lets you keep leather on the wrist without removing it before water.

A calfskin tanned for water

The process is the heart of the model: hydrophobic tanning through the mass, developed by Hirsch with an Italian tannery. The result is a leather certified 100 m water-resistant that does not deform after a swim.

Tool-free

The tool-free Hirsch Quick Release spring-bar system is built in. Two presses fit or remove the strap.

Hirsch edge-folding

The upper leather and the lining, itself impermeable, are bonded together by the Hirsch edge-folding method. The two layers do not work separately: that is what prevents them parting after a few seasons.

Our pairing suggestions
