Strap for De Ville Co-Axial 37.5 Stainless Steel / Silver

The lug width of the De Ville 4831.31.32 is 20mm (measured from center to center between the two attachment lugs). This width is fundamental for selecting compatible straps and ensuring correct proportions on the wrist.

Alligator and shell cordovan represent the finest formal choices, offering elegant texture and superior durability. For more versatile everyday wear, vegetable-tanned calf leather provides authentic character. Fluoroelastomer rubber enables sport-to-elegant transitions without aesthetic compromises to the case.

Use a spring bar tool to release the two spring bar attachments that connect the strap to the case. Insert the flat tip of the tool into the lateral access hole of the lug, push inward to compress the spring, and remove the old strap. Repeat the operation on the opposite side. Install the new strap by first aligning one end, then compressing and securing the other.

Yes, any artisanal strap with a 20mm lug width is fully compatible. Milano Straps offers custom straps crafted in alligator, cordovan, vegetable-tanned calf, and rubber, all contoured for 20mm lugs with an 18-month warranty.

A quality leather strap (alligator, cordovan, calf) typically lasts 3–5 years with daily wear, provided it is subjected to regular maintenance: avoid prolonged water exposure, dry sweat promptly, and apply protective balms occasionally. Shell cordovan, thanks to its superior density, tends to show aesthetic aging more gradually compared to calf leather.
