Strap for De Ville Co-Axial 41 Stainless Steel / Blue

The lug width of the De Ville 431.13.41.21.03.001 is 20mm. This dimension represents the distance between the two case lugs where the strap is attached. To verify it, use a digital caliper by measuring the center of the inner part of one lug to the center of the inner part of the other lug, perpendicular to the case.

For the intense blue dial of the 431.13.41.21.03.001, we recommend straps in warm tones: cognac or tobacco brown alligator, dark burgundy calf leather for sophisticated elegance, or black calf leather for pure formality. In summer, a navy blue or dark grey NATO strap creates chromatic harmony with the dial. A vegetable-tanned leather strap in natural tan communicates discreet modernity.

To change the strap without removing the lugs, use a steel deployante (fold-over clasp) that attaches to the 20mm space available. Gently unscrew the deployante from the previous strap, insert the case lugs into the lateral slots of the deployante itself, and secure the new strap. If you do not have a deployante, you should consult a watchmaker to have the pressure-fitted lugs removed and reinstalled.

Yes, any strap with a 20mm lug width is compatible with the Omega De Ville 431.13.41.21.03.001. Milano Straps offers a dedicated collection of artisanal 20mm straps in alligator, calf leather, shell cordovan, and rubber, crafted with hand stitching and customizable in sizes, colors, and initials.

A quality alligator or shell cordovan strap, with ordinary care, lasts 4–6 years before requiring replacement due to natural wear. The patina that develops increases aesthetic appeal over time. To extend its lifespan, avoid prolonged exposure to humidity and occasionally apply a protective balm specific for leather. A steel deployante reduces wear on the lugs themselves.
