Strap for Da Vinci Perpetual Stainless Steel / Black / French

The lug width (ansa) of the IWC Da Vinci IW3750-31 is 19 millimetres. This measurement is essential for selecting compatible straps: measure the space between the two lugs on the case to verify correct sizing.

We recommend genuine alligator or vegetable-tanned calf leather for the Da Vinci IW3750-31. Alligator emphasizes the case's linearity, whilst calf develops patina over time in harmony with the stainless steel. Shell cordovan is ideal for those preferring dense texture and superior durability.

Use a spring bar tool to extract the attachment pins from the case lugs. Gently press the tool inward to compress the pin's spring, then remove the old strap. Reinsert the new strap by aligning the pins with the lugs and press until you hear the locking click.

Yes, all 19mm straps available on milanostraps.it are compatible with the IW3750-31. You will find a selection of alligator, calf, shell cordovan and technical straps, customizable in length and thread colour.

A quality leather strap (alligator, calf, shell cordovan) typically lasts 3-5 years with daily wear, depending on humidity, perspiration and maintenance. Wearing intervals and periodic cleaning with a damp cloth significantly extend longevity. Artisan straps from Casati Milano include an 18-month warranty.
