Strap for Carrera Calibre 6 39 Stainless Steel / Black / Alligator

The lug width is 20 millimetres. This standard is specific to the WAR2110 and allows you to fit quality aftermarket straps whilst maintaining perfect proportions on the 39-millimetre case. Lug width is measured perpendicularly between the two metal pins on the sides of the case.

It depends on use: alligator with vegetable tanning offers sophistication and develops patina over time; calfskin is versatile and comfortable; shell cordovan provides maximum structure and decade-long longevity. For daily wear, a cotton or FKM rubber NATO is practical and moisture-resistant. The correct choice reflects your wearing style.

Use a spring bar removal tool to gently lever one of the side lugs, freeing the lug pin from the case. Repeat on the other side. Insert the new 20mm strap by sliding the pins into the slots: you'll hear a confirming click. Never force—the pins must sit flush in the slots.

All straps with 20mm lug width are compatible, provided they are fitted with quality elastic loops or deployante clasps. We recommend noble materials: alligator, vegetable-tanned calfskin, shell cordovan, or technical fabrics such as NATO and rubber. Milano Straps provides a collection dedicated to 20mm widths, tested for fit and durability.

A quality alligator or calfskin strap lasts 3–5 years in daily use, developing patina and character. Shell cordovan can exceed 10 years. Duration depends on climate (humidity accelerates aging), frequency of wear and maintenance (dry after rain, avoid direct heat). Casati Milano straps include an 18-month warranty and free servicing in the first year.
