Hirsch Heavy Calf black 22mm — waterproof leather watch strap

22mm waterproof leather watch strap for a large case

The 22mm Heavy Calf leather watch strap in black with contrasting white stitching is a fully impermeable leather, certified 100 m water-resistant. At 22mm the Heavy Calf's thick body balances large-diameter cases without looking slight. It is the model that lets you keep leather on the wrist without removing it before water.

Changing strap in two moves

Hirsch Quick Release spring bars make fitting immediate. No spring-bar tool, no risk of scratching the case lugs.

What waterproof means here

Many leathers are called water-resistant. This one is hydrophobically tanned and certified 100 m water-resistant: a Hirsch process developed with an Italian tannery, applied to the calf and to the lining alike.

Immediate comfort

The Oysterglove Supersoft lining needs no breaking in: it follows the wrist from day one. It is impermeable, and bonded to the upper leather by the Hirsch edge-folding method.

Our pairing suggestions
