Strap for De Ville Prestige Co-Axial 39.5 Stainless Steel / Red Gold / Blue Sunburst

The lug width of the De Ville 424.23.40.20.03.001 is 20 millimetres. This specific measurement should be verified with a digital caliper by measuring the space between the two lugs of the case. It is essential to confirm this dimension before ordering a strap to avoid incompatibility.

For this reference with a two-tone case in red gold and steel, we recommend black alligator with vegetable tanning for a formal look, or dark brown shell cordovan to enhance the warmth of the red gold. For versatile everyday wear, a grained calf leather with a titanium deployant clasp offers excellent practicality without aesthetic compromise.

The replacement requires a spring bar tool (two-pronged instrument) to remove the metal pins that attach the strap to the case lugs. Position the tool in the lateral holes of each lug, gently press the pin to release it, remove the old strap and insert the new one by aligning the holes. Some prefer to entrust this operation to a certified watchmaker to avoid scratches on the case.

Any strap constructed for standard 20 millimetre lugs is compatible. The online collection at milanostraps.it offers a selection of certified models in high-end artisanal leather (alligator, cordovan, calf), all customisable in sizes and finishes. Atelier Casati Milano also allows bespoke creation with direct consultation.

A fine leather strap (alligator, shell cordovan, vegetable-tanned calf) typically lasts 2-4 years with daily use, and up to 5-7 years with occasional use. Longevity depends on water exposure, body perspiration and maintenance care. Regularly cleaning the leather with a soft dry cloth, avoiding prolonged water contact and alternating with other straps significantly extends the life of the piece.
